The Omron VB-3111 is a heavy-duty multiple limit switch built for reliable position detection in automated machinery. It features a bevel plunger actuator and three plungers for multi-point input, enabling compact installation in systems requiring multiple detection points. The switch supports a load of up to 10 A at 250 VAC (resistive) and operates with a minimum speed of 0.1 mm/s up to 0.5 m/s.
With flange mounting and dual side wiring locations, the VB-3111 offers installation flexibility. It provides long-term reliability with a mechanical life of over 5 million operations and electrical life up to 300,000 cycles. The rugged enclosure is rated IP67, offering protection from dust and water. It withstands vibration (10–55 Hz) and shock (up to 1,000 m/s²), while maintaining low contact resistance (15 mΩ max.) and high insulation resistance (100 MΩ min. at 500 VDC).
This model is ideal for conveyors, presses, and material handling systems requiring durable, multi-plunger limit switches.
