Incremental rotary encoder IGM x/y LD

magneticnon-contactanalog

Next to the optical encoders or incremental encoders are the magnetic encoders. Here, magnetic field sensors are used to determine the angular position. The magnetic field generated by a permanent magnet is measured by the sensor. These encoders are preferred for applications where a robust design is required. Characteristics of a magnetic encoder The magnetic encoders are characterised by a contactless and wear-free magnetic incremental encoder. This is equipped with Hall sensors and a permanent magnet pole wheel with alternating polarities. There is a 1-channel and a 2-channel version, each with a 90° phase offset. The output level depends on the supply voltage (5V-24V). The output of the encoder is available either with pull-up resistor or optionally with open collector. In addition, extended protection circuits or an integrated design are possible. • Contactless and wear-free working magnetic incremental encoder • Amplitude depending on the operating voltage • Open collector output • Integrated pull-up resistors • Operating voltage = 4.5V – 24V • Integrated version (IGMi) possible LineDriver function possible (LD) • For further information, please refer to the respective data sheet
