Overview
The solid-state output interfaces to a system controller, which is pre-programmed for a specific sequence of tasks. Mounted in or near
each bin in an assembler’s work station, the sensor job light signals the assembler which bins contain items to be picked in a given
operation and in what order they should be picked.
As the assembler takes a part in sequence, the sensor senses that the part was removed and it sends an output signal to the controller.
The controller then verifies if the correct part was taken and may respond by turning that job light OFF, activating the job light of the next
bin in the sequence.
If multiple parts are to be removed from one bin, the job light may remain ON until the appropriate number of signals is returned to the
controller. If an incorrect part is selected, the control system may be wired to signal an alarm for the assembler and/or a supervisor, or it
may be programmed to interpret the action as a call for parts.

Installation
For push-button models, install the sensor at such a height and in a location that will be easy for the user and/or supervisor to see the
indicator and will be comfortable for the user to press the push-button.
For other models, install the sensor in a location that will be comfortable for the user to break the beam when reaching for the required
part. When multiple sensors will be located in close proximity, to monitor multiple bins for example, mount all the sensors in a similar
sensing position (all mounted at the tops of the bins and pointing down, for example). This may reduce potential optical crosstalk, where
one sensor detects another sensor’s beam.
