Banner Engineering OTBA5QD Optical Touch Button

OTBA5QD Optical Touch Button from Banner Engineering is a momentary-action input device in the OTB Series that replaces traditional mechanical pushbuttons with a touch-activated sensor. Designed for control panels and industrial interfaces, it uses optical sensing to detect a user’s touch and switch a SPDT electromechanical relay output, offering reliable momentary signaling without requiring physical actuation. The unit is specified for 120 V AC input and employs a polysulfone upper housing with a black field cover, delivering a compact, rugged surface suitable for panel mounting. It couples to the system via a 5-pin mini QD connection for quick, secure wiring and streamlined field installation. Applications include machine control, conveyors, and other automation scenarios where reducing hand strain and improving washroom-agnostic durability are advantageous, while still providing definitive on/off signaling through the SPDT output. The OTBA5QD configuration is part of Banner’s Opto-Touch family, designed to deliver repeatable, contact-style signaling in environments where traditional pushbuttons may wear or seize over time. If you’re replacing a mechanical button in a 120 V AC control scheme, the OTBA5QD offers a drop-in tactile-to-electrical interface, combining tactile accessibility with non-contact sensing to minimize wear and maintenance in demanding industrial settings. This model’s black field cover and 5-pin mini QD connector distinguish it within the OTBA lineup, aligning with Banner’s documented specifications for OTB momentary-action devices.
