ASM's PRAS21 series of magnetic non-contact rotary sensors uses an external position magnet to provide an absolute output signal over a 0 to 360 degree measurement range. Thanks to this external magnet this sensor provides continuously wear-free operation. Its standard measurement range is 360 degrees. Smaller measurement ranges can be ordered in 15 degree increments. The sensor output is an analog voltage signal, 0.5 V to 4.5 V. The heigth of its IP60 rated housing is less than 6.35 mm. Its fully potted circuit board has a high level of shock and vibration resistance. The resolution is rated at 0.03 % of full scale (60…360°) and 0.1 % full scale (15…45°), the repeatability is ±0.03 % (60…360°); ±0.1 % (15…45°) and linearity is ±0.5% full scale. The sensor can be installed with M3 screws.
