The Omron VB-5211 is a high-reliability multiple limit switch featuring five roller plungers for multi-point detection in confined industrial spaces. Each plunger is fitted with a 6.8 mm diameter roller to ensure smooth actuation, and the flange-mounted housing supports stable installation on panels or equipment.
This model supports loads up to 10 A at 250 VAC (resistive), with an electrical life of 300,000 operations and a mechanical life of 5 million cycles. It performs at speeds from 0.1 mm/s to 0.5 m/s and resists vibration (10–55 Hz, 1.5 mm double amplitude) and shock up to 1,000 m/s². The housing includes two side-entry wiring ports for easier routing in tight panels.
Built to operate from –10°C to 80°C in up to 95% humidity, the VB-5211 delivers dependable switching in demanding environments. Its metal case ensures long-term performance and protection, sealed to meet IP67 protection.
