Banner Engineering Corporation OTBA5QD Touch Button

The Banner Engineering OTBA5QD is an optical touch button in the OTB Series that provides momentary actuation when touched, using an internal SPDT relay output for control circuits. It features a 5-pin mini quick-disconnect (QD) connection for field wiring and is available with a black housing, with a yellow-cover variant also offered for visibility in certain installations. The relay output is rated up to 7 A at 115 V AC, enabling direct control of loads such as motors, solenoids, or lights in industrial panels, while the device itself is not washdown rated. Designed for panel mounting, this touch button uses Banner’s optical sensing to detect user touch without mechanical wear, delivering reliable actuation in demanding environments. Common applications include control panels, conveyors, and process equipment where a durable, contactless input is preferred. This OTBA5QD is the quick-disconnect variant of the OTBA5, sharing the same momentary behavior and relay output characteristics as the standard model.
