Cylinder sensors work over wide voltage range
Controls using AC voltages are still not uncommon, so when position indication is needed on pneumatic cylinders but feedback is 110V, a solution is at hand in the form of the MR range, from IFM Electronic.
The MR range has many more features than just the operating voltage of course; the simplicity of fitting them cannot be over-emphasised. If the cylinder has a T-shaped slot, the sensor just drops in and a twist of the fastening disc secures it. If there is a tie-rod or another cylinder form, not a problem: IFM supplies many adapters for common cylinder types.
The insert moulding technique used to manufacture the MR range of reed switches renders them extremely robust mechanically and also absolutely sealed against moisture ingress. LED indication is standard, and in-line connectors are offered. Operating voltage of these two-wire devices range from 5 to 120V AC or DC (limted to 50V AC or 60V DC in the connector versions) which on DC will switch PNP or NPN.
IFM is committed to working closely with its customers to develop products which precisely match their needs, and the company provides expert, readily accessible technical support to help users maximise the benefits they gain from IFM products.
