ifm efector MFH/M9H series sensors

With a one-piece metal housing, the MFH/M9H series sensors are very robust. They offer a protection rating of IP65/68/69K for harsh environments and temperature stability from -25°C to 120°C.

The technology relies on an MR measuring cell biased with a permanent magnet in one housing, so only ferrous metals, like tool steel, are detected and an external magnet is not necessary. Other metals, such as aluminium or stainless steel, do not have any effect on the sensor.

The units can not only be used as limit switches in hydraulic cylinders but also on other hydraulic components, like valves or pumps, in mechanical engineering or in the process industry. The MFH design offers a bursting pressure exceeding 2000 bar.

The full-metal housing is made from a single piece and ensures permanent mechanical resistance to pressure fluctuations, shock and vibration. The high-temperature stability allows the unit to maintain its full functionality both in very hot machines and in outdoor applications in direct sunlight. The easy-to-mount sensors come with an M12 or M14 housing.
