INNOVATION IN MOTION The SRH series rotary position sensor manufacturer uses a highperformance 12 bit magnetic rotary encoder ASIC thatincludes integrated Hall elements and digital signalprocessing. The angular position information is provided by a two pole magnet integrated with the sensor shaft. The sensor provides a Pulse Width Modulated signal or an absolute analogue voltage signal by using a low-pass filter circuit. Able to operate from an 8 to 30 Vdc unregulated supply, with a high stability circuit and EMC immunity to 100V/m, this new sensor is ideally suited to operation in extremely hostile applicationssuch as off-road vehicles. Features Benefits ?Contactless technology ?Absolute analogue or digital (PWM) output?Measuring range from 90°to 360°?Temperature error less than 50ppm/°C?Rugged housing and shaft design?Protection up to IP68M?Choice of shaft attachments and mountings?Duplex shaft bearing support?Rapid despatch of any option?CE approved ? Long life and impervious to dither vibration? No loss of position on power down? Maximum sensitivity in all applications? Maximises system accuracy over temperature range? Suitable for extreme environments? Operation in hostile environments including submersion? Interchangeable with existing installations? Optimum performance under vibration and shock? Eliminates customer inventory? Confidence in EMC performance
