It uses an infrared sensing beam and a field cover to detect a finger break without physical contact, delivering a clean, wear-free actuation in industrial controls. The QD version, OTBVR81QD, provides a 5-pin mini quick-disconnect connection for straightforward wiring, while existing non-QD variants are configured with cable options. This model carries a 20–30 V AC or DC supply range and features a SPDT electromechanical relay output, enabling simple start\/stop or signal-branching functionality in automation environments. The housing is black with the field cover color typically specified as yellow on the W\/Y variant, aligning with Banner’s color options for field indicators. As a momentary device, the output returns to its de-energized state when the touch is released, making it suitable for intermittent push-button-style operations in equipment controls and human-machine interfaces. With its optical sensing and rugged field-attachable design, the OTBVR81QD offers a dust- and debris-resilient alternative to traditional touch switches while maintaining compact, panel-friendly dimensions and easy integration into Banner’s broader OPTO-TOUCH ecosystem.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676550365486,"sku":null,"price":406.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8088cb6a-b9c6-4d2e-a5cc-bed19b846ff8.jpg?v=1769551497","url":"https:\/\/plgautomation.com\/products\/banner-engineering-otbvr81qd-momentary-action-optical-touch-button-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
