The Omron VB-4211 is a durable multiple limit switch designed for detecting four positions using individual roller plungers. Each plunger includes a 6.8 mm diameter roller for smooth actuation in mechanical systems. The unit supports flange mounting and includes two side-entry wiring ports for convenient installation in tight spaces.
It supports a switching load of 10 A at 250 VAC (resistive), operates at speeds from 0.1 mm/s to 0.5 m/s, and provides 5 million mechanical operations and 300,000 electrical cycles. The switch offers high resistance to vibration (10–55 Hz, 1.5 mm amplitude) and shock (up to 1,000 m/s²). Contact resistance remains low at 15 mΩ max, and insulation resistance exceeds 100 MΩ at 500 VDC.
Operating within a temperature range of –10°C to 80°C and up to 95% humidity, the VB-4211 is built to perform in harsh industrial environments, backed by a sealed metal housing with IP67 protection.
