Description  The Banner Engineering OTBVR81L is a momentary-action optical touch button from the OTB Series designed for non-contact operator input in industrial control systems. Featuring a black field cover and SPDT electromechanical relay output, it operates on 20–30 V AC/DC power for flexible integration. Its rugged base-mount housing and IP66 protection make it suitable for demanding factory and process environments.     Technical Specifications  Condition New/Never Used Surplus Brand Banner Engineering Category Operator Interface Part Number OTBVR81L Subcategory Optical Touch Buttons Series OTB Series Alternate Mfr Part Number 34040 Operation Momentary Activation Function Optical Sensing Mode Single Point Optical Output Type SPDT Electromechanical Relay Contact Form SPDT (NO/NC) Supply Voltage 20–30 V AC/DC Power Type AC or DC Mounting Thread M30 x 1.5 Mounting Hole Size 30 mm Connection 2 m Cable Number of Pins/Conductors 5 Housing Style Base Mount – Saddle Primary Housing Material Polycarbonate (Lexan) Secondary Material Thermoplastic Primary Housing Color Red Field Cover Color Black Illumination Non-Illuminated IP Rating IP66 NEMA Rating NEMA 1, 3, 4, 4X, 12, 13 Operating Temperature -20°C to +50°C Max Relative Humidity 90% @ 50°C (Non-Condensing) Response Time (Input/Output) 100 ms Physical Dimensions (L x W x H) 59.9 x 43.2 x 48.0 mm Weight 0.30 kg Information About OTBVR81L The OTBVR81L is a base-mount optical touch button engineered within Banner Engineering’s OTB Series for reliable, single-point optical activation. Constructed with a durable polycarbonate (Lexan) housing and thermoplastic components, it is designed to withstand industrial exposure while maintaining consistent actuation performance. The unit supports 20–30 V AC/DC input power and provides an SPDT electromechanical relay output configurable for normally open or normally closed operation. With an M30 x 1.5 mounting thread and 2-meter cable connection, it integrates easily into operator panels, machinery interfaces, and automated production equipment. Key Features:  Momentary Optical Activation: Provides non-contact, single-point optical sensing for hygienic and low-wear operation. SPDT Relay Output: Electromechanical relay supports normally open or normally closed configurations. 20–30 V AC/DC Supply: Compatible with both AC and DC control systems for versatile installation. Rugged IP66 Protection: Sealed housing resists dust and water ingress in industrial settings. M30 x 1.5 Threaded Mounting: Standard 30 mm mounting size for easy panel integration. Non-Illuminated Black Field Cover: Designed for applications requiring a non-visual activation surface. Wide Operating Temperature Range: Operates reliably from -20°C to +50°C. Prewired 2 m Cable: Simplifies wiring and reduces installation time. The OTBVR81L delivers the reliability and precision required for non-contact operator control in industrial automation and machine interface applications.
