IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Product Description
The 45FSL is a DIN rail mountable fiber optic photoelectric
sensor with sophisticated part detection capabilities. Possible
modes of sensing include transmitted beam, diffuse and
retroreflective, allowing the 45FSL to be used in a variety of
complex applications.
Summary of 45FSL Features
S High-speed response—30µs
S High-intensity LEDs—penetrate dusty environments for
reliable detection of targets
S Dual LED indicators
S Output (orange), stability (green)
S Red or white source LEDs
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 Cross-talk protection—prevents cross-talk between 4 or 8
sensors
S Short circuit, reverse polarity, false pulse and transient
noise protection
45FSL photoelectric sensors are designed for use with glass
or 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.

Output and Stability Indicators
Two LEDs (green and orange) indicate a variety of conditions
to facilitate set-up and troubleshooting. The function of each is
described in the table below. Relevant output and stability
data are also shown.

Stability Output is an output feature provided by the 45FSL
sensor which monitors any changes or reduction of reflected
light levels during operation. Reflected light levels must reach
120% of the threshold required for normal operation to
achieve a “Stability Output.” If the sensor detects light levels
less than 120% of threshold 4 consecutive times then the
green LED starts flashing and remains flashing until a stable
light level is achieved (120%) (see illustration below).

8-Turn Sensitivity Adjustment
An 8-turn sensitivity adjustment (potentiometer) is built into the
sensor’s user interface for accuracy in detecting very small
objects or differentiating between colors.
Diffuse Set Up—Light Operate Mode
With target in position, turn sensitivity adjustment clockwise
until orange LED turns on (point A).
With no target in position the green and orange LEDs should
be off. Otherwise turn the sensitivity adjustment clockwise to
max or until orange LED turns on. If orange LED turns on,
then turn sensitivity adjustment counterclockwise until orange
LED turns off (point B).
Set sensitivity adjustment midway between points A and B.
Confirm sensor operation.
Transmitted Beam Set Up—Dark Operate Mode
With no target present, turn the sensitivity adjustment
clockwise to max until the orange and green LEDs turn on
(point A).
Green/orange LEDs should turn off. Otherwise turn sensitivity
adjustment counterclockwise until the green/orange LEDs turn
off. Turn sensitivity adjustment counterclockwise additional
one quarter turn and confirm sensor operation.

Light/Dark Operate Switch
LIGHT or DARK operation modes may be chosen by
changing mode switch.
4/8 Channel Cross-Talk Protection
The 45FSL is equipped to prevent cross-talk to up to 4
ganged sensors providing a 250µs response time or up to 8
ganged sensors maintaining a 500µs response time. Each
sensor communicates through 2 small optic windows that
transmit and receive coded signals (see below).

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.

Wiring the Sensor
Choice of Power Bus, 2m (6.5ft) cable, or 4 pin QD connector
are provided for wiring the 45FSL Series sensors. On the pico
QD models Rockwell Automation/Allen-Bradley recommends
the use of the 889 Series cordsets and patchcords (i.e.,
889P–F4AB–2). Standard 2m (6.5ft) cable lengths are
provided with flying leads for hard wiring. Hard wiring color
coding and pin assignment for QD connectors are as specified
below.
Ganging up to 4 Sensors on DIN Rail
S Mount and align up to 4 sensors on DIN rail
S Move cross-talk selector switch to “4” on all sensors.
(Sensors will not function if cross-talk selector switch is set
to “8” on any sensor.)

The Power Bus option utilizes quick disconnect cordsets
which are prewired with up to four conductors. When ganging
sensors (up to 16 units maximum) using the Power Bus
connection system, select either a 4-wire cable (plus/minus
power output and stability output) or a 3-wire cable
(plus/minus power output) for the first control. For the
additional controls in a system, select either a 2-wire cable
(output and stability output) or a 1-wire cable (output only) to
complete the system.

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.
