Magnetic Rotary Position Sensors offer wear-free operation.
October 13, 2010 -
Supplied in IP60-rated housing that measures less than ¼ in. high, non-contact POSIROT® PRAS21 series uses external position magnet to provide absolute output signal over 0°-360° measurement range. Smaller measurement ranges may be ordered in 15° increments and sensor output is 0.5-4.5 V analog signal with other outputs available upon request. Respective resolutions are 0.03% FS and 0.1% FS from 60-360° and 15-45°, while repeatability is ±0.03% and ±0.1%.

Magnetic Rotary Position Sensors
Elmhurst, IL - New to the POSIROT® family of magnetic rotary sensors is 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 continuously 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 has a height of less than ¼ inch that is rated IP60. 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 favorable 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.
