October 10, 2010 - ASM announces PRAS21 series magnetic rotary sensors. This non-contact position sensor uses an external position magnet to 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 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. Other outputs are available upon request.The PRAS21 series housing has a height of less than ¼ inch 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 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.
