Magnetic sensors

Pressure-resistant sensors

The new operating principle is based on a magneticinductive technology that detects only ferromagnetic metals (e.g. tool steel). The sensor is flush-mountable. Even in case of overflush installation the sensor detects the steel target and shows reliable switching behaviour.
Besides use as a limit switch in hydraulic cylinders, the sensor can also be used on other hydraulic components such as valves or pumps.

Sensors

Magnetic sensors are used for the detection of positions without contact or wear and tear in control technology. They are used where inductive proximity switches reach their limits. The advantage: Compared to inductive switches magnetic switches have a considerably higher sensing range and smaller housings.
Only prerequisite: The object to be detected must be equipped with a magnet because the switch only responds to magnets.

Speed sensors for drives and axes

The high switching frequency of 15,000 Hz as well as the extended temperature range of -32...125 °C make the new magnetic ifm speed sensors your perfect partner for the detection of rotational speed and direction of rotation on axes, drives and shafts. The detection of both direction of rotation and rotational speed is integrated into one housing.
The sensors have fully electronic magnetic measuring cells, so that they function reliably without contact even in case of heavy soiling. They are "magnetically biased" with an integrated permanent magnet. The ferromagnetic teeth on a toothed wheel alter the existing magnetic field so that a corresponding switching signal can be generated.
