Description
The 45LSP is a family of optical fork sensors housed in a plastic enclosure. Fork sensors offer self-contained transmitted beam sensing, ideal for applications that require reliable parts detection. A simple push button teach-in sensitivity adjustment, several connection options and multiple mounting features (via side thru-holes, rear threaded inserts or optional dovetail bracketry) make the 45LSP an economical, easy-to-use solution for typical applications such as small part detection, edge detection, part counting, gear tooth detection and dimension verification.
Features
Detection of objects as small as 0.2 mm (0.0078 in.)
Highly visible power and output LED indicators with output
indication along both sides of the fork
Remote teach and teach button lock on 4-pin models
Light or dark operate selectable
Multiple mounting options: thru-holes, threaded holes and
dovetail
Easy installation with no alignment required

For detection of objects less than 0.9 m (0.035 in.), the object should be placed ≥ 10 mm (0.39in.) away from the LED light source.
For use in NFPA 79 applications only Adapters providing field wiring means are available from the
manufacturer. Refer to manufacturers information.

Operational Instructions
Sensitivity Adjustment
With no target present, press the teach button for approximately three seconds until orange LEDs are flashing synchronously: first threshold is taught. With the target present, press the teach button for approximately one second. If the green LED flashes and stays on then thresholds have been taught, and the sensor is ready to operate. If both LEDs are flashing synchronously then the sensor cannot detect the object and no thresholds have been taught.
Sensitivity Adjustment During a Running Process (optimum detection of very small parts)
With the chosen running process being the only thing in the scanning area, press the teach button for approximately three seconds until orange LEDs are flashing synchronously. Press the teach button until a minimum of one process cycle is completed. If the green LED flashes and stays on then thresholds have been taught, and the sensor is ready to operate. If both LEDs are flashing synchronously then the sensor cannot detect the target and no thresholds have been taught.
L.O./D.O. Setup
Press the teach button for approximately 13 seconds. Orange LEDs should flash alternately. When you release the button, the green LED should remain flashing. When the green LED is flashing , the output is inverted by pressing the button. The orange LED shows active function. Do not press the button for 10 seconds. The green LED stops flashing and the present output function is saved. The sensor is ready to operate.
Maximum Sensitivity
With no target present, press the teach button for approximately three seconds until orange LEDs are flashing synchronously. Again, with no target present, press the teach button for one second. The sensor is set to maximum sensitivity and is ready to operate.
Maximum Stability—Factory Setting (maximum resistance to contamination)
Cover the light source. Press and hold the teach button until the orange LEDs are flashing synchronously. Keep the light source covered, press the teach button for one second. The sensor is set to maximum stability and is ready to operate.
Modification of the Emitter Frequency in Case of Mutual Interference
Switch one sensor off. Press the teach button during power ON. The orange LED flashes one time; frequency one, normal operation (switching frequency 2 kHz). Keep the button pressed for another three to five seconds. The orange LED flashes twice; frequency two, normal operation (switching frequency 2 kHz). Keep the button pressed for another three to five seconds. The orange LED flashes three times; frequency one, detection of very small parts possible (switching frequency 2 kHz). Keep the button pressed for another three to five seconds. The orange LED flashes four times; frequency two, detection of very small parts possible (switching frequency 1.5 kHz). Release the button to place the sensor in operating mode. Switch other sensor on again.
