Banner Engineering Corp. STBVR81 Automation Switch

The Banner STBVR81 is a self-checking safety touch button from Banner’s STB Series, designed as a rugged operator input for machine-safety circuits. It accepts a 20–30 V AC or DC supply and provides two complementary SPST relay outputs (one normally closed, one normally open) for safe interlock, guard monitoring, or two-hand control logic. The unit ships with a 2 m (6.5 ft) integral cable and has no built-in connectors, requiring hardwired wiring into your control circuit. The STBVR81 features a black polyetherimide upper housing for durable performance in industrial environments and is IP66-rated for protection against dust and water ingress. Its enclosure-friendly ratings include compatibility with NEMA 1, 3, 4, 4X, 12, and 13 when installed in appropriate systems, helping it withstand challenging conditions. Use this device as a dedicated safety input in wired automation setups, often in conjunction with Banner’s safety ecosystem for two-hand control or interlock configurations to help ensure operator engagement and safe machine operation.
