Momentary Optical Touch Button for 120 V AC Systems

The Banner OTBA5 is a momentary-action optical touch button designed for 120 V AC supply circuits. It uses a single-point optical sensing mode with a black field cover and a thermoplastic polysulfone housing. An SPDT electromechanical relay provides the output, making the device suitable for industrial control panels that require a non-mechanical actuation method.

Sustained Operation Within Rated Temperature

The button operates continuously between -20 °C and 50 °C with a maximum relative humidity of 90 % at 50 °C non-condensing. Input and output response times are each capped at 100 ms, so repeated actuations remain consistent during extended shifts. The IP66 and NEMA 1, 3, 4, 4X, 12, 13 ratings confirm the enclosure resists dust and water ingress under prolonged exposure.

Base-Mount Housing with 2 m Cable and M30 Thread

A saddle-style base mount with an M30 x 1.5 thread secures the unit to panels or brackets, while the 2 m (6.5 ft) five-conductor cable exits the housing for direct wiring. The compact body measures 59.9 x 43.2 x 48.0 mm, allowing installation in tight enclosures without additional mounting hardware. Buyers who need a maintained-action switch or a different supply voltage range should select an alternative model.

Questions about this item

Does the OTBA5 generate noticeable heat or noise when powered continuously at 120 V AC?

The optical touch button uses a solid-state sensing element and an electromechanical SPDT relay rated for 100 ms response time; it has no fan or moving parts beyond the relay contacts, so heat and audible noise are minimal during all-day operation.

What wiring and mounting hardware must I already have to install this button?

You need a 105-130 V AC supply, a 5-conductor cable run to the 2 m flying lead, and an M30 × 1.5 threaded cut-out for the saddle-mount base.

Will the OTBA5 work reliably next to older 120 V AC relay panels in the same enclosure?

Yes — the NEMA 1, 3, 4, 4X, 12, 13 and IP66 ratings mean it tolerates the same temperature range (-20 °C to 50 °C) and humidity (90 % non-condensing) as legacy industrial panels.
