Rotary Position Sensors

Extending its POSIROT family of magnetic rotary sensors, ASM Sensors has introduced the PRAS20/PRAS21 series for use in the medical equipment industry. They are quickly and easily installed with M3 bolts. The non-contact device uses an external position magnet to reliably provide an absolute output signal over a 0 to 360° measurement range. Smaller measurement ranges in 15° increments may be ordered. The sensor output is an analog voltage signal, 0.5-4.5 V. For the PRAS20 series, 0.5-10V and 4-20 mA outputs are also available. A redundant output is an available option in the PRAS20 series. The ultra-compact PRAS21 series IP 60 rated housing with a height of < ¼” that can fit into the tightest medical equipment applications. The circuit board is fully potted to provide 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 device’s repeatability is ±0.03 % (60-360°) and ±0.1 % (15-45°), where as the linearity is ±0.5% full scale.
