Magnetic angular sensors

Posirot PRAS3 magnetic angular position sensor uses an internal, contact-free permanent magnet to determine the angular position in harsh environments. They feature a compact 1.4-in. diameter housing, with measurement ranges available in 15° increments: 0-15°, 0-30°, 0-45° up to 0-360°. Two extra strong ball bearings handle axial and radial loads along sensor’s 10-mm shaft. Three analog outputs are available — 0.5-4.5 and 0.5-10 V and 4-20 mA. They offer ±0.03 % over the full scale resolution and repeatability; 0.3% over the full scale linearity. ASM Sensors Inc., (630)-832-3202, www.asmsensors.com
