The Omron VB-2221 is a rugged multiple limit switch designed for precision detection in demanding industrial systems. It includes two roller plungers with 6.8 mm diameter rollers and supports flange mounting for stable, fixed installation. The unit houses four independent built-in switches, enabling complex or redundant signal outputs from a single actuator movement.
With a rated load of 10 A at 250 VAC (resistive), the VB-2221 handles high electrical loads with ease. It supports operating speeds from 0.1 mm/s to 0.5 m/s and is built for long life: 5 million mechanical operations and 300,000 electrical operations minimum. The switch features low contact resistance (15 mΞ© max.), high insulation (100 MΞ© at 500 VDC), and is rated for ambient temperatures from β10Β°C to 80Β°C.
Its sealed construction meets IP67 standards, making the VB-2221 suitable for use in harsh, dusty, or wet environments where reliable detection and durability are essential.
