Banner Engineering OTBVN6QD Optical Touch Button

The Banner Engineering OTBVN6QD Optical Touch Button is a momentary-action input device from the OPTO-TOUCH OTB Series, designed for base-mount (saddle) installation with a MINI-style integral quick-disconnect for compact, rugged control panels. It uses a single-point optical sensing element for finger-activated actuation and provides a complementary NPN (sinking) output in a 4-pin quick-disconnect configuration, with models available in black cover variants. The unit is powered from 10 to 30 V DC and is rated IP66 for washdown-ready protection, compatible with Banner amplifiers and a range of NEMA/UL enclosures (NEMA 1, 3, 4, 4X, 12, 13). Its primary housing is thermoplastic polysulfone, with a black upper housing and a fiber-reinforced VALOX base construction, contributing to a compact, durable form factor. Electrical characteristics include a voltage specification of 10–30 V DC, a “Max Input Response Time” and “Max Output Response Time” of 100 ms, and a configuration that supports normally open/normally closed wiring depending on the circuit. The OTBVN6QD variant, including the W/Y color option, is documented as an obsolete part, with Banner advising customers to review replacement options for a current equivalent. Operationally, the device delivers optical actuation with no moving parts, reducing wear in high-cycle environments and suiting touch-based start/stop or user-interface inputs where rugged, sealed buttons are required. The operating range includes a -20°C to 50°C window with non-condensing humidity up to 90% at 50°C, reinforcing suitability for demanding industrial environments.
