Omron VB-2111 Limit Switch
Omron VB-2111 is a VB Series multiple limit switch with two bevel plungers and flange construction. Operating speed ranges from 0.1 mm/s to 0.5 m/s, with mechanical frequency up to 120 operations per minute and electrical frequency up to 30 operations per minute. IP67 protection, 15 mΩ maximum initial contact resistance, 100 MΩ minimum insulation resistance, and 300 VAC rated insulation voltage are specified. The VB-2111 belongs to the VB Series within the multiple plunger limit switch range from Omron limit switch products. Its bevel-plunger actuator distinguishes it from roller-plunger versions.

The Omron VB-2111 Limit Switch uses two bevel plungers with flange construction. Operating speed ranges from 0.1 mm/s to 0.5 m/s, while mechanical frequency is 120 operations per minute and electrical frequency is 30 operations per minute. Mechanical durability is five million operations minimum. Electrical durability is 300,000 operations minimum under the listed 10 A at 250 VAC resistive-load test condition. Initial contact resistance is 15 mΩ maximum, insulation resistance is 100 MΩ minimum at 500 VDC, and rated insulation voltage is 300 VAC. IP67 protection is specified.
The model operates from -10 to 80°C with 35 to 95% relative humidity. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Destructive shock resistance is 1,000 m/s² minimum and malfunction shock resistance is 200 m/s² minimum. The two-plunger format and bevel-plunger actuator are the strongest mechanical identifiers. For a two-plunger VB model using 6.8 mm roller plungers and the same flange construction, see the VB-2211.
