Dependable and rugged design for angle
sensor
Sensor provides contact-free and wear-free angular measurement from 0 to 360 degrees using a position magnet.
ASM is claiming a new benchmark for angular position sensors with the development of a magnetic angle sensor in a very compact M12 housing The PRAS1 sensor provides absolute position measurement over a full 360-degree sensing range and is part of the successful Posirot family of magnetic angular sensors

New magnetoresistive non-contact position sensor
The Posimag position sensor uses a compact non-contact sensor head which moves above a magnetic strip; it is robust and fast, and has high resistance to dust, moisture and many fluids.
With only a 0.5in diameter and overall length of less than 2in, this small sensor saves space and can be installed in the tightest locations.
The contact-free and wear-free angular measurement from 0 to 360 degrees is achieved by using a position magnet.
The PRAS1 has a typical resolution of 0.1 degrees and yields an analogue signal through the use of a D/A convertor.
Three different analogue outputs are available: 4-20mA, 0.5-4.5V and 0.5-10V.
The industrial housing is rated up to IP68.
With its dependable and rugged design, the PRAS1 angle sensor is well suited for angle monitoring in a wide variety of heavy duty applications such as factory automation equipment, variable valve controls, mobile working machines etc.
