ASM Sensors introduces the magnetic multi-turn encoder technology POSIHALL.
- Measures true-absolute
- Robust alternative to optical encoders
- Measures absolute angular position of shaft over multiple revolutions by utilizing gear coupled multi-hall sensor system that uses magnetic nonius (vernier) principle
- Ensures reliable and correct positioning even after disturbances such as power failure
- Can be mounted directly onto machine’s rotation axis
- Available in protection class up to IP69
- Sensor electronics completely enclosed and protected by rugged housing
- Non-contact magnetic multi-hall technology is able to reliably detect measuring data even if machine housing is filled with water or oil
- Sensor body has an integral shielding against magnetic fields
- Works in environments with magnetic field strengths up to 0.5 Tesla
- Available with redundant outputs for safety applications
- Operate reliably and precisely with high levels of shock and vibration resistance
- Operating temperature range of -40-85 C (-40-185 F)
- Measurement range for PH36 model is up to 31 x 360 degree revolutions and for PH58/PH68 models up to 255 x 360 degree revolutions
- Available with digital (SSI, CANopen snd CAN SAE J1939) and analog outputs
- Single turn linearity is 0.3%
- Reach resolution of 14 bit
