U Shape Photoelectric Sensor

This miniature U shape photoelectric sensor is a very efficient sensor that can be used in a variety of applications that require speed detection, pulse counting and position control. It uses the LM393 comparator chip which gives outputs a clean and stable digital signal. This sensor feature is used for sensing the obstacles passing through this slot. The output of the sensors indicates whether the slot is blocked or not and it can be connected to an external relay for creating limit switches or it can be connected to an active buzzer module to create alarms. Specifications • Chip: LM393, groove coupler H2010 • Groove Coupler Width: 10 mm • Working Voltage: 5 VDC • Size: 27.6 mm x 20 mm x 17 mm
