The Omron VB-2211 is a durable multiple limit switch featuring two roller plungers and a flange-type housing, ideal for dual-position detection. Designed for long-term industrial use, it supports high mechanical durability of over 5 million operations and electrical switching up to 300,000 cycles at 10 A, 250 VAC (resistive load).
This model operates smoothly at speeds from 0.1 mm/s to 0.5 m/s and is built to withstand vibration (10–55 Hz) and shock (up to 1,000 m/s²). The cable exits from two side ports for flexible wiring, and the body includes a sealed structure rated IP67 for protection against dust and temporary water immersion.
With a high insulation resistance of 100 MΩ and low contact resistance (15 mΩ max.), the VB-2211 ensures signal integrity and safe switching performance. It is ideal for complex industrial systems requiring dual actuation points, such as conveyor lines, machine tools, or material handling equipment.
