Banner Engineering OTBVP6QDH Optical Touch Button

OTBVP6QDH is Banner Engineering’s OTB Series momentary-action optical touch button designed for rugged industrial control. It operates from 10–30 V DC and provides a complementary PNP (sourcing) output through a 4-pin M12 integral quick-disconnect, with normally open and normally closed operation options. The unit features a thermoplastic polysulfone upper housing and an M30 x 1.5 mounting thread, is IP66-rated for washdown environments, and uses a single-point optical sensor for actuation. Its compact footprint measures 59.9 × 43.2 × 48.0 mm and relies on a 4‑pin QD connection for wiring. The OTB series also includes a variant, OTBVP6QDH W/Y, with a yellow field cover, offering the same electrical interface but a different field-cover color for visibility in certain installations.
