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.
