Non-Contacting Rotary Position Sensor Is Rugged

The 9950 non-contacting rotary position sensor combines the superior durability of non-contacting technology with excellent EMI capability, into a single analog output, lower-cost, and more compact package. The rugged, completely sealed device has a life expectancy of up to 35 million cycles, making it well-suited for the harsh environments found in industrial, agricultural, and off-highway applications. The unit’s integrated Hall-effect chip is enclosed in a liquid-tight, fully sealed plastic package that meets protection seal class IP67. Performance characteristics include an electrical angle of up to 120°, ±2.0% standard linearity, and an operating temperature range of ?40°C to 125°C. Accuracy is ±3.0% of full scale at room temperature and ±4.0% of full scale over the operating temperature range. The rugged device can withstand 10g vibration, from 20 to 2000 Hz; a 50g shock; and a half-sine pulse of 5 ms duration. An integral connector mates to the industry-standard Packard Electric METRI-Pack 150.2 series for easy plug-in installation. The 9950 measures only 50 by 37.5 by 34.1 mm. Pricing is from $21.00 each in production quantities, with delivery in eight weeks for standard products. BEI DUNCAN ELECTRONICS, Irvine, CA. (949) 341-9500.
