Banner Engineering OTN-001A Opto Touch Sensor is a zero‑force, touch‑activated optical switch in Banner’s OPTO‑TOUCH family that activates its output when a finger enters the touch area and interrupts the infrared beam. It uses a 10–30 V DC supply, a single sensing beam, and a SPDT output (one normally open, one normally closed) available in models with either electromechanical relays or solid‑state outputs. Mounted on a 30 mm threaded base (M30 x 1.5) with a compact 59.9 × 43.2 × 48.0 mm housing and IP66 protection, it is designed as a rugged general input for machinery start/stop, interlock, or generic touch‑initiated control tasks.
