Wear-free rotary sensor

摘要

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° measurement range.By using an external magnet, this sensor provides continuously wear-free operation. The measurement range is 360° and may be ordered with smaller measurement ranges in 15° 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 6.35mm 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 favourable price per performance and ultra flat profile of the PRAS21 series make it suited for numerous OEM applications.
