Limit switches, AL and K244
series

■Description

FUJI AL and K244 series limit switches
have wide application in such industrial
equipment as machine tools, printing
machines, and transfer machines. These
switches feature a sturdy aluminum die­cast housing that is highly resistant to oil,
water, and dust, and long mechanical life
— 10 million operations minimum.

AL series

AL and AL-S series limit switches
feature a forced contact opening
mechanism.
Under abnormal conditions, the
mechanism forces the contacts open to
prevent pitting and fusing.
Gold-plated silver contacts with
scrubbing action have high reliability.

KKD07-027 SF-2025 SK-580

General information

Forced contact opening limit
switches, AL and AL-S series

■ Description

The AL and AL-S series limit switches
feature a forced contact opening
mechanism. This mechanism prevents
contact welding and subsequent
malfunctioning. These series therefore
result in extremely dependable system
controls.
The AL series is available in standard
sizes and the AL-S series is compact
versions of the AL types.

■ Features

• The forced contact opening
mechanism is provided so as to
overcome contact problems.

• Gold-plated contacts and a self
cleaning action ensure contact
reliability.

• Sealed construction
Double oil seals prevent moving parts
and contacts from being contaminated
by exterior oil, grime and grease, an
advantage in dirty industrial locations.

• Operational mode indicator can
replace existing cover with lamp
indicator cover when required.
An LED or neon lamp is used
depending on supply voltage.

• Contact mechanical design
Contact operating mechanisms can be
selected according to the application­snap, overlap and normal actions

• Conform to IEC Standard

mechanism

This mechanism does not operate under
normal conditions. However, when the
switch plunger overtravels under
abnormal conditions the mehcanism
comes into operation and forcibily opens
the NC contacts thus preventing contact
welding.
This action improves the dependability of
electrical systems.

General information

■ Directional contact operation

AL-N1, AL-N2 and AL-N3 can be
modified in their operational directions.
They will switch in both directions, or in
only one direction, either clockwise or
counterclockwise. The adjustment is
easily carried out by removing the
operating head and changing the
plunger as shown in the photograph.
After the plunger has been reassembled,
replace the head and tighten the screws.
Check operation by moving the arm in
the desired direction.

■ Actuating slider face angles and

approach speeds

Although K244 limit switches have an
excellent performance they should not
be operated at an extremely high speed
or extremely low speeds, since these
conditions will cause contact trouble and
reduce the mechanical life expectancy of
the devices. The slider face angles and
approach speeds should be kept within
the following recommendations.

 Push rod plunger type

This type of switch obtains the
movement from the vertical travel of the
rod.
Speed : Max. 1m/sec

Min. 0.015m/sec
Snap-action types can be used at
speeds less than the minimum value.

 Roller lever type

The actuating slider face angles and
speeds should be within the following
range.
The maximum angle of the slider face:

α

1=45°α2=30°

Snap-action type switches can be used
at speeds less than the minimum value.

■ Travel operating force curve

The curve indicates forces to operate the
contact.

Reversing roller lever momentary­contact limit switches, K244g첸R

■ Description

These limit switches are designed to
detect the movements in the vertical
direction. The switch body is identical to
the standard type except that one roller
is extended from the housing.
The performance is the same as for the
standard type.

 Standard  Reversing

■ Ratings

Type Thermal Making Breaking current *

Right side roller

■ Actuating slider face angles and

approach speeds

K244 limit switches have an outstanding
performance and will have a long service
life under normal conditions. They are
designed to carry out 3,000 operations
per hour but if they are operated at an
extremely high speeds or on the contrary
at extremely low speeds contact trouble
could develop which would reduce the
mechanical life expectancy of the
devices.
Reversing roller levers are provided with
sliders in their vertical direction. The
slider face angles and approach speeds
should be kept within the range shown
by curves. The maximum angle of the
actuating slider is α1=45°, α2=30° and
under. Snap-action types can be used at
speeds less than the minimum value
given.

HK244 and WK244 limit switches have
been developed for use in low voltage
and low current circuits. They will
operate effectively in 3 Volts AC or DC,
5mA circuits although they are
recommended that they are used in 48
Volts or 110 Volts circuits for best
results.

HK244 limit switches

HK244 limit switches are provided with
pure silver contacts. The movable
contact carries out a scrubbing action
during make/break operation ensuring
good connections at all times.
The switch body is molded from a high
performance resin, and versions with
transparent plastic covers and with
aluminum die-cast housing are also
available.

WK244 limit switches

The bifurcated contact is made of pure
silver and like the HK244 series they are
also suitable for use with low voltage
circuits. The dimensions and operating
strokes are similar to the standard type.

AES, AER and PM type proximity
switches (Magnetically-operated reed
switches)

In the standard type PM the reed switch
element and the sensing magnet are
separate elements. The AES type is also
a separate type but is a miniaturized
version. In the AER type the sensing
magnet element and the reed switch are
integrated in one housing.

■ Features

• Since these proximity switches make
use of a permanent magnet no
external power source is required to
operate the reed switch.

• The dry reed contact switch is
dependable in operation and has an
extended service life.

• The unit strongly resists vibration and
is both water-and dust-tight (except for
AES type).

• Either an AC or DC power source can
be used for the reed switch output.

• Compact in design and easy to install
anywhere.

• Can be mounted on a steel frame (In
this case the effective operating
distance is reduced by one-half).

■ For further information

See pages 05/51, 52, 54, 55.

basic performance. Its shape, size, and
material are stipulated. Iron is usually
used as material.

 Operating distance

The operating distance is the
distance along the center axis of the
head from the sensing head to the point
where a metal plate traveling along the
path actuates the switch.
Normally the operating distance means
this distance in vertical direction.

The following curves indicate typical
operating distances. Values for
aluminum or copper will be less than 1/2
those indicated for iron. In order for an
object to be detected, its dimensions
must be no smaller than 30 × 30mm, or
no larger than 70 × 70mm. Objects
smaller or larger will not be detected,
regardless of material.

 Response curve

This curve shows the detect-to-reset
range with object distance from the
head. The switch operates when the
object approaching form the left reaches
point P on curve ‘a’, and resets when the
trailing edge of the object reaches point
Q on curve ‘b’.
The switch also resets when the object
is withdrawn from point P to R on curve

General information

Magnetically operated type

■ Operating

These switches comprise a sensor and a reed switch element,
which closes when a magnetic object approaches.

■ Reed switch

The constructions of the reed switch and its magnetic element
are shown in the diagram. The reed switch is made up of two
magnetic reeds in an airtight glass tube. The 2 reeds are
magnetized when they come within the magnetic field of the
magnetic element. In this case the tips of these 2 reeds have
positive and negative charges respectively and are attracted to
each other. When the magnetic field is removed the magnetic
charge is lost and the reed switch opens.
FUJI’s reed switches are designed to operate in the same
manner as the snap-action of conventional limit switches.

Reed switch closes when the metal piece is out of ‘X’ region
between the magnet and the reed switch.
When the metal piece passes through the ‘X’ region the reed
switch will open. Thus the reed switch opens as soon as ‘c’ the
tip of the metal piece reaches ‘X’ region and closes as soon as
‘d’ the end leaves ‘Y’ region.

Proximity Switches

PE2-C

Inductive proximity switches–
Cylindrical type, PE2-C

The lineup of PE2-C series proximity
switches has been augmented by the
addition DC 3-wire system switches with
NPN and PNP transistor outputs and 2­wire system switches usable for both AC
and DC applications.

These new switches are characterized
by:

• A stable operating indicator composed
of a two-color (red and green) LED that
enables easy and reliable setting of
detection range

• Smaller dimensions and longer
detecting distance due to incorporation
of new IC

• Four ways to configure DC 2-wire
systems, DC 3-wire systems (which
provide NPN and PNP transistor
outputs) and two-wire systems usable
for both AC and DC applications. This
wide choice of configurations makes it
possible to choose appropriate switch
for the circuit.

The DC 2-wire system

• Reduces wiring cost and labor

• Can be connected to such high
impedance load as small relays, PLC,
and NC equipment without risk of reset
failure due to leakage currents of not
exceeding 0.8mA and a residual
voltage of 3V.

• Consumes very little current and
places no burden on the power supply
serving PLC.
Make a power supply for the sensor
unnecessary.

• Enables easy connection on site to
load equipment having sink- and
source-current input specifications.

• Has protective circuit to protect against
short-circuit, reverse polarity, and
surges.

The DC 3-wire system:

• Available in 16 types of units, shielded
or unshielded, of varying diameter, and
providing two types of output

• Also available with PNP output
transistors for European machine tool
applications.

PE2-C

AF91-505

• Has the same external dimensions as
the PE1 series which is not equipped
with stable operating indicator.

The 2-wire system switch usable for both
AC and DC applications:

• Can be operated from sources from 20
to 250V DC and 40 to 250V AC.

• Reduces wiring cost and labor.

• Is unpolarized, eliminating hazard of
reverse polarity connection.

■ Optical axis adjustment

 Transmission type

Swinging the light source and receiver up and down and right
and left when no objects exist, set and fix the light source and
receiver to the center within the range where the operation
indicator (orange) is lit or is turned off (Dark-ON). At the same
time make sure that the stability level indicator (green) is lit.

 Retroreflective type

Swinging the unit and reflector up and down and right and left
when no objects exist, set and fix the unit and reflector to the
center within the range where the operation indicator (orange) is
lit or is turned off (Dark-ON). At the same time make sure that
the stability level indicator (green) is lit.

■ Sensitivity adjustment

 When carrying a normal detection, set the sensitivity adjuster at the maximum sensitivity value by turning it fully clockwise.
 Sensitivity adjustment is necessary for the following cases.

• Transmission type: To detect translucent or minute objects

• Reflection type: To detect objects with inadequate contrast

 Carry out the sensitivity adjustment as follows. (When excessive power is added to the sensitivity adjuster, it might be damaged.)
