Dual Hall Effect Sensors

Sentech's Dual Hall Effect Sensors offer reliable sensing solutions under challenging environmental conditions, from initial concept and design to retrofitting on existing hydraulic equipment or machinery to improve control and steering.

These sensors are capable of simultaneously detecting speed and rotation. They produce a frequency signal on channel A and a 90° phase shifted frequency signal on channel B, enabling the Quadrature signal to ascertain rotation direction.

With their compact contact surface and diameters as small as 12mm, these sensors are designed to function under extremely high pressures. Available in various configurations, and are tailored to suit your specific application needs.

Features

  • Two digital output signals 90° out of phase to each other
  • Detecting speed down to zero
  • Direction, forward and reverse, of ferrous targets
  • Constant amplitude square wave output
  • Wide speed range
  • Customize to the needs of your specific mechanical environment
  • Available in standard and metric thread and smooth housing sizes 303 Stainless Steel and other housing materials available.

Applications

  • Hydraulics
  • Turbines
  • Compressors
  • Transmissions
