Duncan Electronics Introduces Dual Output Hall Effect Sensor

    TUSTIN, Calif.--July 30, 2001--Duncan Electronics, a division of BEI Technologies Inc., has introduced the 9900 Dual Output Hall Effect Rotary Sensor featuring rugged, non-contacting position sensing technology.
    Designed with two sensors in one compact package for the optimum combination of redundancy and cost economics, the Model 9900 offers Hall effect electronics built within a rigid enclosure to withstand the harshest off-highway conditions and demanding industrial applications.
    This redundant device offers two independent, fully programmable outputs that allow for offset, gain, slope and temperature compensation. The 9900 Sensor includes a programmable Hall chip set that can be custom configured to meet the exacting application requirements for complete flexibility.
    Featuring a housing with an integral connector, the 9900 Sensor provides a liquid tight, fully sealed package. Mechanical travel is +/- 90(degree) with typical active electrical angle of +/- 45(degree), including both clockwise and counterclockwise rotations. Custom specification electrical travel designs are also available.
    The 9900 Sensor incorporates a symmetrical set of rotating magnets with fixed sensor configuration for improved accuracy and reliability. Standard features include an operating temperature range of -40(degree)C to +85(degree)C with even wider ranges available from -40(degree)C to +125(degree)C upon customer specification.
    Accuracy is +/-2% of full scale at room temperature and +/-3% of full scale over-operating temperature range.
    Other outstanding performance characteristics include mechanical life rated to 35 million full cycles. The rugged device can withstand 5 Gs vibration, 60-2,000 Hz; 50 Gs shock, and half sine pulse of 5msec duration. The 9900 is connector compatible to industry standard Packard Electric METRI-Pack 150 series for easy plug-in installation. The device also features industry standard EMC protection.
    Immediately available, typical unit pricing starts at $19.80 in 100-piece quantities.
