Omron VB-6211 Limit Switch
Omron VB-6211 is a multiple limit switch with six roller plungers for high-density multi-point position detection in a single switch assembly. Each plunger uses a 6.8 mm roller for smooth mechanical contact, while flange mounting provides stable installation and two side cable entries simplify wiring. Operating speed ranges from 0.1 mm/s to 0.5 m/s, and the switch provides 5 million minimum mechanical operations with IP67 protection. The VB-6211 belongs to the VB Series within the six-plunger multiple limit switch range from Omron automation products for multi-stage sequence, travel, and position feedback where several coordinated detection points must be combined in equipment requiring several coordinated sensing stages.

The Omron VB-6211 Limit Switch uses six roller plungers, each fitted with a 6.8 mm roller, for high-density multi-point position detection. The six-plunger arrangement combines several sensing points in one switch assembly, while flange mounting provides a stable installation base. Two side cable entries keep wiring accessible from the sides of the housing. Operating speed ranges from 0.1 mm/s to 0.5 m/s, with up to 120 mechanical and 30 electrical operations per minute. IP67 protection supports use around dust, water, or oil, while operation extends from -10 to 80°C with 35% to 95% relative humidity.
Mechanical durability is specified at 5 million operations minimum, while electrical durability reaches 300,000 operations minimum at 10 A, 250 VAC resistive load. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The VB-6211 withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 200 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit applications requiring several sequential position signals without using multiple separate switch housings. For a related flange-mounted VB model with five roller plungers and the same two-side wiring arrangement, see the VB-5211 model.
