Notes for Designing PC Board and Circuit

• Use 1.6-mm-thick glass epoxy PC board with drilled holes.

• Design a circuit so that the LB/LBW series can operate within the rated voltage and current range. Make sure that inrush
current and voltage do not exceed the rating.

• Minimum applicable load is 5V AC/DC, 1 mA on gold contacts. Applicable range is subject to the operating condition and
load.

• Since the *2.8-mm-wide terminal touches the PC board as shown on the right, short circuit may occur with pattern lines.
Design a circuit that prevents short circuits.

Safety Precautions

• Turn off power to the unit before installation, removal,
wiring, maintenance, and inspection.
Failure to turn off may cause electrical shocks or fire
hazard.

• For wiring, use wires of a proper size to meet the volt-
age and current requirements.

• Improper soldering or failure to tighten the terminal
screw may cause overheating and fire.

Single Board Mounting

UP series miniature pilot light single board mounting types can be
mounted with LB/ LBW series on the same panel.
Follow the instructions below on
single board mounting.

LED Kit

1. Mount the LED kit to the PC board.

Temporary mounting

1. Note the polarity of the
terminals and insert the

Polarity

Pay attention to the polarity of the power supply as UP series units
do not contain a diode for protection against reverse polarity. The
long terminal is positive and the short terminal is negative.

Current Limiting Resistor

When using a UP series unit without a built-in current limiting
resistor, connect an external current limiting resistor. Calculate the
resistance using the following formula.

Resistance

(Ω)

=

* Rated Current (
G (green) : 0.002A
Forward Voltage (Vf) = R (red), W (white) : 2V
G (green) : 2.7V

Note: Use a resistor of higher resistance than the calculated value (Ω)

Countermeasures against Dim Lighting

See page 66.

Wiring

Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. SnAgCu type lead-free solder is recommended.
When soldering, do not touch the pilot light housing with the
terminal. Do not bend the terminal or apply excessive force to the
terminal.

Notes on Panel Mounting

Tightening torque should not exceed 0.49 N·m. Do not use pliers.
Do not tighten with excessive force, otherwise the locking ring will
be damaged.

PC Board and Circuit Design

Use glass epoxy copper clad laminate, double-sided through-hole
PC boards with a thickness of 1.6 mm.

Instructions

Wiring

1) Solder the terminals at 350°C within 3 seconds using

a 60W soldering iron. Sn-Ag-Cu type is recommended
when using leadfree solder. When soldering, do not touch
the LB series with the soldering iron. Also ensure that no
tensile force is applied to the terminal. Do not
bend the terminal or apply excessive force to the
terminal.

2) Use non-corrosive liquid flux.

Terminal Cover

Solder/tab terminal

Insert the terminal cover into the contact block with the TOP
markings on the contact block and the terminal cover in the
same direction.
Note: When wiring, insert the lead wires into the terminal

cover holes before soldering.
After wiring, the terminal covers cannot be installed.

Mounting Holes and Assembly Procedure

• For wiring, use wires of a proper size to meet voltage
and current requirements. Solder correctly according
to the instructions in "Wiring" and "Notes on Terminal
Cover." Improper soldering may cause overheating
and create a fire hazard. Also, when using tab termi­nals, use receptacles of appropriate size.

. . . . .

51

Operating Environment

• Do not use the LB/LBW series where corrosive gases ex­ist or under an environment exceeding the operating tem­perature and humidity ranges. Otherwise, damages due to
contact failure or change of surface color may occur.

• Major parts of the switch are plastic. Scratches or dam­ages may occur when scraped with a sharp object or
applied with excessive load or shock. Note that this may
cause operation and appearance failure of the operator
and bezel.

• Adherence of detergent, cutting oil, or special chemicals to
the switch may result in operation failures and appearance
failures such as change of surface color.

Handling

Contacts (micro switch)

When using NC (normally closed) and NO (normally open)
contacts of the same microswitch, avoid connections of
different voltages, or connections of different types of power
supplies. Failure to observe this instruction may cause a
short-circuit.

Protection against oil (IP65)

The LB series has been tested according to JIS C 0920:
Appendix 1 by using water insoluble cutting oil Class N3,
No. 8 (JIS K 2241) to prove that the switches will not be
damaged by oil drops or splashes. This may not apply to
special types of oils. Contact IDEC for details.

circuit may cause the LED lamp to illuminate dimly even
when the output is off.
When the LED lamp is illuminated by a transistor output,
take the following measure.

Switch Guards

Opening/closing the Switch Guard

When opening/closing the switch guard while the switch
guard is not installed on a panel, make sure to hold the
hinge. Holding the base might result in damage. Also do not
apply force on the guard in other than open/close directions,

otherwise the hinge may be damaged.

Rubber Gasket when using LB9Z-K2 Switch
Guard (remains open) for Round/Square Units

Choose to use or not to use the rubber gasket for the switch
referring to the conditions described below. Note that the
degree of protection is IP40 with or without the rubber
gasket.

• When the panel thickness is up to 2.8mm

Install the switch onto the switch guard with rubber gas­ket, and mount on the panel.

Noise

LED elements deteriorate due to extraneous noise,
resulting in significant decrease in luminance, hue change,
or failure of lighting. When such effects are anticipated, take
a protection measure shown below. However, measures
may differ according to operating environment and condition

(Zener diode reference value)
Zener voltage: 4.3 to 4.7V

Static Electricity (UP Series)

UP series are delicate products that may be damaged by
static electricity Make sure to take measures to prevent
static electricity.

• When the panel thickness is 2.8 to 3.2mm

Remove the rubber gasket from the switch and install the
switch onto the switch guard, and mount on the panel
(discard the rubber gasket).

• Single board mounting

Remove the rubber gasket from the switch and install the
switch onto the switch guard, and mount on the panel
(discard the rubber gasket).
