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.
