Magnetic rotary position sensors

POSIROT PRAS20/PRAS21 magnetic rotary sensors are designed for use in medical equipment. Non-contact position sensors use an external position magnet to reliably provide an absolute output signal over a 0 to 360° measurement range. External magnet helps provide continuous, wear-free operation. Output is an analog voltage signal, 0.5 to 4.5 V. For the PRAS20 series, 0.5 to 10 V and 4 to 20 mA outputs are also available. A redundant output is an available option in the PRAS20 series.

Ultra-compact PRAS21 series housing has a height of less than ¼ in. and is rated IP60. Circuit board is fully potted to provide a high level of shock and vibration resistance. Resolution is rated at 0.03% of full scale (60…360°) and 0.1% full scale (15…45°); repeatability is ±0.03% (60…360°); ±0.1% (15…45°); and linearity is ±0.5% full scale.
