The Omron VB-3141 is a rugged multiple limit switch built for applications requiring repetitive mechanical actuation. It features three bevel plungers and a side-entry terminal layout, making it suitable for space-limited machine panels. This model handles loads up to 10 A at 250 VAC and supports switching speeds from 0.1 mm/s to 0.5 m/s.
Its durable construction ensures a mechanical life of over 5 million operations and 300,000 electrical operations under resistive load. The unit maintains stable contact performance with low contact resistance (15 mΩ max) and strong insulation resistance (100 MΩ min at 500 VDC).
The VB-3141 withstands harsh industrial environments with shock resistance up to 1,000 m/s², vibration resistance (10–55 Hz), and an operating temperature range from –10°C to 80°C. Rated IP67, it’s ideal for conveyor systems, jigs, fixtures, and automated mechanical assemblies that require multi-point detection in a compact form.
