The Omron VB-4111 Limit Switch is a multiple limit switch with a bevel plunger actuator, four plungers, and flange construction. The operating-speed field is listed as 0.1 mm to 0.5 m/s in the source. Mechanical operation frequency is 120 operations per minute and electrical operation frequency is 30 operations per minute. Initial contact resistance is 15 mΩ maximum, insulation resistance is 100 MΩ minimum at 500 VDC, and insulation voltage is 300 VAC. IP67 protection is specified. Mechanical durability is five million operations minimum, while electrical durability is 300,000 operations minimum under the listed 10 A at 250 VAC resistive-load test condition.
Operating temperature ranges from -10 to 80°C with no icing, with relative humidity from 35 to 95%. Malfunction vibration resistance is 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 10 A at 250 VAC figure is kept only as the electrical-durability test condition rather than converted into an independent rated-load claim. The four-plunger configuration is the clearest difference from the three-plunger VB models with similar supporting specifications. For a related three-plunger bevel-plunger version, see VB-3121.
