03102296 (commonly with the full suffix S01) is a "Bottom Light Barrier Sensor" used in ASM SIPLACE pick-and-place machines; it is also referred to by this same name within spare parts supply channels.
Core Function and Purpose
This sensor serves as a photoelectric sensing component within the equipment's safety and position-detection system. In the SIPLACE X series (such as the X4i or TX2i), light barriers are employed to monitor the limit positions of moving parts or to provide collision protection—for instance, the calibration of a collision-detection light barrier for a feeder axis involves determining whether the light path is interrupted or clear at a specific height. Typically installed beneath the moving axes, the bottom light barrier detects whether mechanical components have reached a safe reference position, thereby preventing equipment damage caused by overtravel or accidental collisions.
