RF-MH50A/56A – Stainless Steel Horizontally Mounted Level Switch with M12 Connector

This all stainless steel level switch is horizontally mounted to give either a high level or low level signal and is reversible meaning that it can be either normally open or normally closed. The RF-MH50A has an all 304 grade contruction and the RF-MH56A is constructed from 316 grade stainless steel.

The switch comes with a 2 metre cable with M12 connector but can be made with various cable lengths (please get in touch with your requirements, minimum order quantities may apply).


When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
