Magnetic Rotary Position Sensors – ASM PRAS21

Automated Control Engineering Group (A.C.E.) and ASM introduce the newest member of the POSIROT® family of magnetic rotary sensors; the PRAS21 series. This non-contact position sensor uses an external position magnet to provide an absolute output signal over a 0 to 360 degree measurement range.

By using an external magnet, this sensor provides continuous wear-free operation. The measurement range is 360 degrees and may be ordered with smaller measurement ranges in 15 degree increments. The sensor output is an analog voltage signal, 0.5 V to 4.5 V. Other outputs are available upon request.

The PRAS21 series housing is rated IP60 and has a height of less than 6.35mm. The circuit board is fully potted to yield 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 favourable price per performance and ultra flat profile of the PRAS21 series make it uniquely suited for numerous OEM applications. The sensor is easily installed with M3 screws.
