Omron VB-2211 Limit Switch
Omron VB-2211 uses two roller plungers with 6.8 mm rollers and flange construction. The switch operates from 0.1 mm/s to 0.5 m/s and is specified for five million mechanical operations minimum. Electrical durability is 300,000 operations minimum under the listed 10 A at 250 VAC resistive-load test condition. IP67 protection, 15 mΩ maximum initial contact resistance, and 100 MΩ minimum insulation resistance are provided. The VB-2211 belongs to the VB Series within the dual roller plunger switch range from Omron switching products. Its flange configuration is an important selection detail.

The Omron VB-2211 Limit Switch uses two roller plungers, each with a 6.8 mm roller, together with flange construction. The operating-speed range extends from 0.1 mm/s to 0.5 m/s. Mechanical operation frequency is 120 operations per minute and electrical frequency is 30 operations per minute. Mechanical durability is five million operations minimum, while electrical durability is 300,000 operations minimum under the source-listed 10 A at 250 VAC resistive-load test condition. IP67 protection, 15 mΩ maximum initial contact resistance, 100 MΩ minimum insulation resistance, and 300 VAC rated insulation voltage are specified.
Operating temperature ranges from -10 to 80°C with relative humidity from 35 to 95%. Malfunction vibration resistance is 10 to 55 Hz at 1.5 mm double amplitude. Shock resistance is 1,000 m/s² minimum for destruction and 200 m/s² minimum for malfunction. Flange construction distinguishes this model from another two-roller-plunger version whose structured row specifies no flange. For that alternative, see the VB-2241.
