IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Description
The 45LST optical fork sensor is designed for small part
detection on machines and conveyors. With available slot
widths from 2mm to 225mm (0.08in to 8.86in), these sensors
feature adjustable sensitivity and selectable NPN/PNP with
LO/DO energized output in a heavy-duty IP65 aluminum
housing. Applications include label detection on clear
substrates, cap detection on bottles, and part sensing on
conveyers for the packaging and material handling industries.
The 45LST sensors are also ideal for the automotive, paper,
and food industries.
The 45LST optical fork sensor maintains all ratings that are
necessary for all applicable industries today: IP65, cULus and
CE marked for all applicable directives.

Sensor Setup
Initial setup includes mounting the sensor securely and then
providing power through a 4-pin pico cordset. The initial
factory settings have the threshold on the sensor preset so
that most opaque objects may be sensed. To adjust sensitivity
turn adjustment screw clockwise to increase or
counterclockwise to decrease.
