Magnetic rotary position sensors

Article Type: New products From: Sensor Review, Volume 31, Issue 2

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°-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 (0.5-4.5 V). Other outputs are available upon request.

The PRAS21 series housing has a height of less than 1/4 in. (6.35 mm) 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 percent of full scale (60°-360°) and 0.1 percent full scale (15°-45°), the repeatability is ±0.03 percent (60°-360°);±0.1 percent (15°-45°) and linearity is ±0.5 percent 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.
