## Description

The OP.180 is an infrared reflective limit switch unit built around the ITR9606 sensor, which pairs an infrared emitting diode with a silicon phototransistor in a 180° (straight-through) orientation. When an object passes between the emitter and receiver, the IR beam is broken, triggering a digital signal change. Connects via a standard Grove cable for plug-and-play integration with M5Stack controllers and other Grove-compatible boards. The fast response time and high sensitivity make it well-suited for counting, position detection, and safety interlock applications. Key Features ITR9606 Sensor – Infrared emitter and phototransistor pair for reliable detection 180° Layout – Straight-through beam orientation for slot-style detection Fast Response Time – Quick detection for high-speed counting applications High Sensitivity – Reliable switching with consistent IR signal Grove Interface – Simple plug-and-play connection Digital Output – Clean high/low signal when beam is interrupted Ideal For Door and gate switches Machinery control and safety interlocks Object counting and position sensing Encoder and scanner applications Non-contact switching Package Contents 1× OP.180 infrared reflective unit 1× Grove cable Resources Example Code (Arduino) – GitHub repository
