Rotary/Angular Position Sensor

Sentech is pleased to announce a new range of competitively priced Hall Effect Rotary Position sensors providing angular position information for various control applications.

A magnetically biased, Hall-effect integrated circuit (IC) senses rotary movement of the actuator shaft over a set operating range. Rotation of the actuator shaft changes the IC’s position relative to the magnets position, the resulting change in flux density is converted into a linear output.

The Solid-state Hall-effect technology provides non-contact operation, long service life and a low torque actuation making them ideal for throttle speed, foot pedal, lift, shuttle, tilt and steering position and control applications in a variety of industries.


  • Solid State Hall Effect Technology
  • Ultra Long-Life 50 million cycles
  • Eight Possible Operating Ranges (50°, 60°, 70°, 90°, 120°, 180°, 270° and 360°)
  • Tolerant to Over Travel
  • Maximum ESD Sensitivity of +/-7kV
  • Cost Effective
  • Linearity of 2% or less
  • Offset and gain control can be specified by the customer within practical constraints

  • Off Road

Digital MPU

Xensor pioneered the use of custom IC to digitize the analog signal generated by a magnetic sensor, eliminating the use of expensive hybrid chips or backup electronic circuitry.

Digimag Digital Magnetic Pickups revolutionized the use of magnetic sensors for the computer peripherals industry, where low cost and compact design count.

Providing a digital pulse output sensing a change from non-magnetic to magnetic material moving past the pole piece. The rise-fall times and amplitude of the output pulse is independent of the speed of the magnetic discontinuity. The maximum rise time is 1,000 nanoseconds; the maximum fall time is 50 nanoseconds.
