Omron VB-3141 Limit Switch
Omron VB-3141 is a multiple limit switch with three bevel plungers for multi-point mechanical position detection in one switch body. The three-plunger arrangement supports coordinated sensing across several positions, while the no-flange construction and two side cable entries suit installations where mounting space and wiring direction matter. Operating speed ranges from 0.1 mm/s to 0.5 m/s, with IP67 protection and long mechanical service life for repeated switching. The VB-3141 belongs to the VB Series within the multiple limit switch range from Omron machine control products for multi-point travel, sequence, and position detection with compact mechanical feedback in machine and automation assemblies.

The Omron VB-3141 Limit Switch uses three bevel plungers for multi-point mechanical position detection from one switch assembly. The three-plunger arrangement supports several sensing points without installing separate switch bodies, while the no-flange construction and two side cable entries suit compact mounting and side-access wiring. 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 the operating temperature range extends from -10 to 80°C.
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-3141 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 specifications suit multi-point sequence and position detection where bevel plungers and a no-flange body are required. The bevel actuator provides direct contact without the rolling surface used on roller-plunger versions. For a related three-plunger VB model using roller plungers with the same no-flange format, see the VB-3241 model.
