Penny + Giles, a business group of Curtiss-Wright Controls (Christchurch, UK), has introduced the NRH275DR rotary position sensor featuring a low-profile sensor housing and separate permanent magnet assembly. With no contacting mechanical parts that can wear, the sensors can be used in extreme and hostile environments where installation space may be limited. The sensor features a fully encapsulated 12-bit Hall effect sensor system that can withstand high shock and vibration, can operate at temperatures from -40 to 140 °C, and is IP67-rated for dust protection and water immersion to a depth of 1m for 24 hours.

The sensor operates from a 5Vdc regulated supply, and has two independent sensor power supplies and outputs that enable full redundancy. It enables a range of output configurations such as CH1/CH2 angle, output type, and output direction. It also features maximum output signal noise of less than 1mV, which means no additional signal filtering is required on the output signals.
