Magnetic Sensors for Linear and Rotary Monitoring

Movement is everywhere, whether rotating or linear. This requires reliable monitoring, control, and measurement. Magnetic incremental rotary encoders and linear magnetic sensors provide the required input signals reliably, contact-free, and without any moving parts. The sensors are encapsulated in 10x40x15 mm PA6-plastic enclosures and rated IP 67, making them highly suitable for use in industrial environments.

Because the sensors have no bearings or other moving parts, they are not subjected to any kind of wear. The impulse count and resolution of these rugged movement sensors are also impressive. Presuming a 64-pole ring magnet with a diameter of 56 mm, the MDFK 10 with standard interpolation rate generates up to 16,384 steps per revolution. The maximum resolution of the sensor optimised for linear measurement is 5 microns. Both versions provide two 90° phase shifted digital signals at their push-pull outputs to detect the direction of rotation or travel. The incremental rotary encoder also generates a reference impulse on each revolution of the magnetic rotor.
