Banner Engineering OTBVR81 Optical Touch Button

The Banner Engineering OTBVR81 Optical Touch Button delivers non-contact touch activation for industrial machine controls, providing ergonomic actuation without mechanical wear. Part of the OTB Series, it operates from 20-30 VAC/DC, has an SPDT relay output with 1NO/1NC contacts, and uses a momentary-action, infrared optical sensing housed in polysulfone with a 30 mm threaded mount and an integral cable. Its IP66-rated enclosure and rugged construction suit harsh manufacturing environments and make it suitable for applications such as packaging equipment, assembly workstations, material handling systems, presses, and production lines requiring reliable touch activation. Common replacements include Banner OTBVR81QD, OTBVN6, and OTBVP6.
