Honeywell HOA6991T55 IR Opaque Optoschmitt Sensor

The Honeywell HOA6991-T55 is part of the HOA series, which combines an infrared emitting diode and an Optoschmitt detector within a black thermoplastic housing. It detects objects blocking the IR beam, triggering a switching action. The sensor offers flexibility with choices in detector aperture, mounting tab configuration, detector output configuration, and housing material. The opaque polysulfone housing effectively rejects ambient light, making it suitable for applications demanding high position resolution. Cleaning recommendations include methanol and isopropanol. The HOA6991-T55 is a versatile solution for object detection and position sensing in industrial environments.
