DFR1129

DFR1129 is a Gravity: Infrared Light Photo Interrupter module that integrates a high-performance ITR9608 photoelectric switch. Its compact design and easy operation make it an ideal choice for electronic projects and applications. Whether for robotics, automation equipment, or counting systems, this module provides precise photoelectric detection and efficient signal processing. The photo interrupter is a device that operates by blocking light with an object. Its main components include a light emitter and a light receiver, both arranged face-to-face within same enclosure. When an object passes through the light path between the emitter and receiver, the light at the receiver is obstructed, triggering the operation of the photoelectric sensor. Suitable for counter: facilitates object counting on production lines, speed detection and measurement: provides pulse signals for calculating rotation speed and frequency, smart card switch: detects card insertion and removal for power control.

• Operating voltage range from 3.3 to 5V
• Light source wavelength is 940nm (Infrared)
• Photonic gap is 5mm
• Interface type is PH2.0-3P
• Product dimension is 27x32mm
