Omron VB-2241 Limit Switch
Omron VB-2241 is a two-plunger VB Series limit switch using 6.8 mm roller-plunger actuators and construction without a flange. Operating speed is specified from 0.1 mm/s to 0.5 m/s, while mechanical durability reaches five million operations minimum. The source lists 300,000 electrical operations minimum under a 10 A at 250 VAC resistive-load test condition. The VB-2241 belongs to the VB Series within the two-plunger roller switch range from Omron limit switch products. IP67 protection and 15 mΩ maximum initial contact resistance are also specified.

The Omron VB-2241 Limit Switch uses two 6.8 mm roller plungers and is specified without a flange. Operating speed extends from 0.1 mm/s to 0.5 m/s, with mechanical operation up to 120 operations per minute and electrical operation up to 30 operations per minute. Mechanical durability is five million operations minimum. Electrical durability is 300,000 operations minimum at the stated 10 A, 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 listed.
The switch operates from -10 to 80°C and 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 absence of a flange is the clearest source-supported construction difference from VB-2211. For the related two-plunger roller model with flange construction, see the VB-2211.
