| | Oct 24, 2012 — Elmhurst, IL - ASM Sensors, a leading manufacturer of position sensors, offers the extension of the POSIROT® family of magnetic rotary sensors, the PRAS20/PRAS21 series for use in the medical equipment industry. This non-contact position sensor uses an external position magnet to reliably 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 maximum 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. For the PRAS20 series, 0.5 to 10V and 4 to 20 mA outputs are also available. A redundant output is an available option in the PRAS20 series.
The ultra-compact PRAS21 series housing has a height of less than ¼ inch that is rated IP60 that allows it to 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 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 medical OEM applications, such as surgical table positioning. In medical applications that do not require water tight housings, the PRAS20/21 series position sensor can replace large, costly sensors with metal housings. The sensor is quickly and easily installed with M3 bolts.
