The PRAS21 magnetic rotary position sensors from ASM Sensors use an external position magnet to provide an absolute output signal over a 0 to 360˚ measurement range. The external magnet enables continuously wear-free operation. The device may be ordered with smaller measurement ranges in 15° increments. The sensor output is an analog 0.5-4.5 V signal. Other outputs are available upon request. The housing height is less than ¼ inch, rated to IP60, and the circuit board is potted to yield high resistance to shock and vibration. The resolution is rated at 0.03% of full scale (60…360°) and 0.1% of full scale (15…45°).
