The Omron VB-3111 Limit Switch is a multiple limit switch with a bevel plunger actuator, three plungers, and flange construction. The supplied row lists an operating-speed range of 0.1 mm to 0.5 m/s. 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 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 10 A at 250 VAC value is retained only as the electrical-durability test condition, not as a separate rated load. Key identifiers are the bevel plunger, three-plunger configuration, flange construction, 15 mΩ contact resistance, 300 VAC insulation rating, and IP67 protection. A source field also states “Two on the side,” but its label is not visible, so no function is assigned to it. For another VB Series three-plunger model, see VB-3211.
