Piab VS Mini Vacuum Switches Review: Specs, Price and Applications

Piab's VS mini vacuum switches are small, light, low-cost switches for vacuum sensing in decentralized ejector-based systems. Plastic versions are VS4015 and VS4016; metal versions are VS4118 and VS4128.
They are factory preset for true plug-and-play installation, provide a digital output, use push-in or threaded connections and accept an optional T-adapter to combine multiple switches into one output. Metal versions use M12 cable assemblies with a 90° swivel connection.
Quick Verdict
Simple, reliable grip confirmation. Factory presets remove setup errors, and the light plastic version suits fast robots.

Design and Operating Principle
In decentralized systems, each cup or group has its own ejector, so vacuum switches are needed close to the cup to confirm grip. Mini switches fit there without adding weight.
Factory presetting means technicians do not need to adjust switch points, eliminating a common source of errors.
The T-adapter chains several switches to one output, simplifying wiring when all cups must confirm before the robot moves.
Integration and Selection
Choose plastic for lightweight robot tools and metal for robust automotive applications. Wire digital outputs to the robot or PLC.
Use the T-adapter for series confirmation.
