Pneumatic cylinder position sensors operate at 110V

The insert-moulding technique used to manufacture the MR range of reed switches renders them extremely robust mechanically, and provides sealing against the ingress of moisture. LED indication is fitted standard, and in-line connectors are offered. Operating voltages for these two-wire devices ranges from 5 to 120V AC or DC (limited to 50V AC or 60V DC in the connector versions), which on DC will switch PNP or NPN.
