Banner Engineering OTBA5 Optical Momentary Finger Touch Button Sensor

OTBA5 is Banner Engineering's OPTO-TOUCH OTB Series optical momentary-action touch button with a black field cover, designed to replace mechanical push buttons and deliver true zero-force finger activation. It operates on 120 V AC (105–130 V AC range) and provides a SPDT electromechanical relay output, with a 2 m integral cable for straightforward installation. The unit uses single-point optical sensing, features a polysulfone upper housing, and is non-illuminated, with a black field cover for a clean, low-profile look. It is designed for surface or base flush mounting with a 30 mm mounting hole, and carries IP66 protection along with NEMA 1, 3, 4, 4X, 12, 13 ratings for reliable operation in demanding environments.
