Product Description

The 45FVL is a DIN rail mountable fiber optic photoelectric
sensor with sophisticated detection, diagnostic and self-teach
capabilities. Possible modes of sensing include transmitted
beam, diffuse and retroreflective, allowing the 45FVL to be
used in a variety of complex applications.

Summary of 45FVL Features

S Self-teach capability—Allows the 45FVL photoelectric

sensor to determine an optimum sensitivity and hysteresis
setting for a specific application.

S Manual or automatic sensitivity adjustment.
S Back-Lit LCD Display. Clearly displays various operating

modes, functions and diagnostic information.

S Visible red, green, white, or blue light source.
S Selectable 40ms off delay output timer. “Pulse stretcher”

useful in high speed applications when the output pulse
must be lengthened to allow time for the machine logic to
respond.

S DIN rail mountable. For installation convenience, a steel

bracket is supplied for specific mounting requirements.

S “Power Bus” option. Interface which allows user to

jumper power on several DIN rail mounted units to reduce
unnecessary wiring.

S Dual channel interference protection. Prevents crosstalk

between 2 sensors.

S Short circuit protection.
S Reverse polarity protection.
S False pulse protection.
S Transient noise protection.

The 45FVL photoelectric sensors are designed for use with
plastic fiber optic cables up to 2.2mm diameter. An adaptor is
supplied with the sensor for use with 1.25mm diameter plastic
fiber optic cables. No tools are required to attach or remove
fiber optic cables. Special glass fiber optic cables are also
available.

Operation Selector Switch

When the selector switch is in the RUN position (see following
example), the sensor will function normally, and all settings
are locked from adjustment. The SET position unlocks the
sensor’s settings, allowing the user to either adjust the sensor
manually, or use the self-teach functionality. When
adjustments are complete, return the switch to the RUN
position (settings become locked). If a manual sensitivity
adjustment is required a user can unlock this setting by
(quickly) switching from RUN to SET to RUN. The sensor will
display a flashing “S” on the LCD display, and the user can
now adjust the sensitivity setting. The sensor will automatically
return to the locked condition 10 seconds after sensitivity
adjustment is complete.

Locking

Two Adjustment Buttons

The red button is used to teach the sensor, change the
frequency and to increase the sensitivity.

The black button is used to change the operating mode,
indication mode and to decrease sensitivity.

Both buttons are inactive in the RUN mode.

Mounting the Sensor

How to Attach Sensor to DIN Rail

Attach front hook of the photoelectric
sensor onto rail (or Mounting bracket)
and press rear end of sensor down
until unit snaps into place.

How to Detach Sensor from DIN Rail

Pushing the sensor unit forward,
pull up on the front of the sensor
until the front hook is detached.
Remove sensor.

Side Mounting Sensor with Bracket

Fasten mounting bracket assembly
using M3 screws. Tightening torque is

0.8Nm max. Attach front hook of the
photoelectric sensor onto mounting
bracket and press rear end of sensor
down until unit snaps into place.
