Banner Engineering OTBVR81 Photoelectric Sensor

Banner Engineering's OTBVR81 is a zero‑force optical touch button in the OTB Series that replaces traditional mechanical push buttons with a touch‑activated input. It provides an SPDT relay output and operates from a 20 to 30 V AC/DC supply, with a 9‑foot attached cable for straightforward panel wiring. Available with a standard black cover or an optional yellow cover variant (W/Y), the OTBVR81 is designed for momentary‑action operation: a light touch activates the switch via optical sensing, eliminating the need for mechanical actuation. This makes it well suited as a drop‑in replacement for mechanical push buttons on control panels, machines, hoppers, guards, or other industrial equipment where a clean, low‑wear input is desirable. As part of Banner's Opto‑TOUCH family, the OTB Series emphasizes touch‑activated interfaces that reduce wear compared with conventional push‑button switches, and the OTBVR81's compact footprint and integrated wiring support quick panel integration and reliable operation in demanding environments.
