Momentary touch sensor for industrial control

The Banner OTBVR81 is a single-point optical touch button designed for machine interfaces and process control panels. It operates on 20-30V ac or dc supply and provides a SPDT electromechanical relay output. The M30×1.5 mounting thread suits standard panel cut-outs in automation cabinets.

Sustained operation within rated environmental

The sensor maintains reliable actuation across a -20°C to 50°C temperature range with up to 90% non-condensing humidity. IP66 and NEMA 1, 3, 4, 4X, 12, 13 ratings protect against dust and water ingress during continuous duty. Maximum input and output response times are 100 ms each, giving predictable timing under steady load.

Replaces worn mechanical push-buttons in harsh areas

The optical actuation eliminates moving plunger wear, making it suited for high-cycle stations where mechanical contacts degrade. The polysulfone housing resists common industrial cleaning agents. It is not suited for applications requiring latching action, audible feedback, IO-Link communication, or hazardous-area certification.

Questions about this item

How much heat does the OTBVR81 generate when it runs continuously at 30 V?

The sensor draws power from a 20-30 V ac/dc supply and its SPDT relay switches within 100 ms, so heat output stays low in normal industrial use.

What voltage supply must I already have to power this sensor?

You need a 20-30 V ac or dc source with at least five conductors to match the 2 m cable and relay output.

Will the M30×1.5 thread fit the mounting holes on my older control panel?

The housing uses an M30 × 1.5 mounting thread; panels cut to that metric size will accept it directly.
