New Hall-Effect Rotary Sensor for Harsh Environments| Construction News

The new Model 9970 Hall-effect position sensor from BEI Sensors ships within two weeks and features 50mm mounting hole spacing for drop-in compatibility with existing installations.

A 1.5 Series AMP Superseal connector comes standard and the well-sealed, IP67 and IP69K package uses non-contacting technology. That makes the sensor exceptionally rugged and ideal for harsh environments. With an operating life of up to 35 million cycles and a temperature rating from -40° to +257°F, the 9970 has been designed to perform in tough conditions typical of off highway vehicles. The heavy-duty design allows precise motion-control feedback in a variety of wash-down and dirty and dusty applications. 

Standard output configurations of 0-5V ratiometric or 4-20mA make it easy to use across many applications. Unlike comparable sensors, the 9970's ability to travel 360° allows it to be used over a large range of rotary motion. Its over-voltage protection prevents possible damage from installation errors. To limit radio interference, the 9970 resists electromagnetic interference up to 200V/m, about the strength of a microwave.

The  Model 9970 is ideal for harsh environments such as steering and pedal position for off-highway construction and agricultural vehicles as well as throttle positioning in marine applications.  It is also suitable for mining and material handling equipment and for valve position indication or control in processing systems.
