Photo Interrupter Module (T-Shape)

This Photo Interrupter Module is widely used in motor speed detection, pulse count, the position limit, etc. It will trigger a signal when light between the sensor's gap is blocked.

It works with 3.3V to 5VDC, and gives a HIGH on DO pin when the beam is blocked, and a LOW output when the beam is unblocked. 

Note: Sensor only. TT Motor and encoder disc are not included.

Features:

• Power: 3.3V ~ 5V
• Gap width: 6mm
• Schmitt trigger, stable wave form and signals

Dimension: 26.8mm × 15mm × 18.7mm
