ASM Sensors offers an improved catalog featuring a range of Posirot rotary position sensors as well as Positilt single- and dual-axis inclinometers. The Posirot family uses a permanent magnet to translate the angular position to the sensing element, while the PRAS/PRDS series features an absolute, noncontact magnetic measurement technology. The company's PMIS series consists of an increment encoder with a magnetoresistive-read head and a permanent magnet wheel with multiple magnetic poles to offer high-resolution models that yield more than 300,000 pulses per revolution. The Positilt family of inclinometers is based on micro-electrical-mechanical systems technology, known for improved accuracy, reliability, and stability. Inclinometers also are available in rugged, stainless-steel housings to ensure long life under extreme environmental conditions.
