article image Small but powerful – the robust vacuum switch has many clever and practical features

This recent release from J. SCHMALZ GmbH and Millsom Vacuum Handling is a vacuum switch with two digital outputs and an easy to use switching point teach button.

The switch can be used universally as a measuring and switching device for safety monitoring tasks, for the optimisation of cycle times or for energy-saving functions. It is particularly suitable for applications that demand extremely precise switching, excellent repeatability, high switching frequencies and a long operating lifetime.

The electronic circuitry in the switch generates output signals via two separately programmable digital outputs. A two-colour LED indicator shows the user when the switching point of each output has been reached. The user can thus see the status of the switch at any time and can, if necessary, adjust the switching points with the aid of the teach button.

With a width of only 10mm and a weight of only 6 grams, the small vacuum switch requires little space, can be mounted vertically or horizontally, and can be connected in various ways: with the standard mounting flange, with an M5 thread, or with a 6mm plug-in tube connector.

The vacuum switch can be set to switching points between -1 and 0 bar and withstands pressures of up to 5 bar. Electrical connection is made via a 4-pin M8 connector. As a further option, the vacuum switches are also available with adjustable hysteresis.
