Robust ,Budget magnetic encoder

Magnetic encoders provide angular information by noncontact tracking of a multipole ring magnet based on a magneto resistive sensor. Depending on the angle between the sensor and the magnetic field, the device generates analog signals containing the angular information. These signals are fed into an electronic circuit for additional conditioning and processing.
Baumer Electric's rugged and easy to mount sensor generates 1152 pulses per revolution when used in conjunction with a ring magnet of 18 pole pairs. Angular resolution of the device can be partly determined by selecting appropriate ring magnets. The IP67 protected sensor contains absolutely no moving parts and is not subject to wear. The air gap between magnet and sensor can be up to 0,8 mm without sacrificing system accuracy.
Available locally from Temperature Controls, the unit's encoder is powered in the range of 8 to 30 V. Two 90º offset squarewave signals are available at the output. These allow the direction of rotation to be determined in addition to the angle of rotation and the speed of rotation. The application temperature range of this magnetic encoder is between -25 and +85º C. The same system can also be used as a length measuring system. A magnetic band is used in place of the pole wheel, in this way resolutions finer than 70 µm can be achieved.
