Hall Effect Zero Speed Sensors

Hall Effect speed sensors are integrated units containing the transducer, magnet (as applicable), and electronics that are used to provide zero speed sensing. We manufacture them in both oriented and non-oriented models. In addition to the standard models, all Hall Effect series sensors are available in custom lengths, diameters, configurations, and mounting threads.

These hall effect gear tooth sensors are designed to sense the angular rotation of ferrous metal targets and are popular for a wide variety of applications including propulsion gear speed and direction, shaft speed and direction, as well as process-based applications that require operation at extremely slow speeds, such as measuring movement of a conveyor.

Motion Sensors Inc. specializes in customizing our sensors, and these hall effect transducers can be made to suit in terms of electrical specifications such as output logic levels, as well as physical parameters such as thread types, lengths, mounting flanges, cabling and connectors.

• Oriented Hall Effect Zero Speed Sensors – H Series
  The H series of sensors is based on Hall Effect sensor technology, which can sense a change in target motion from true zero to 20 KHz. These sensors incorporate a magnet within the sensor, enabling them to sense ferrous metal as well as magnet targets and can be optimized to detect fine as well as large pitch targets. These sensors integrate a preamplifier/signal conditioner within the sensor housing that provides excellent noise immunity and greater transmission capability. The output frequency of these sensors has a square pulse waveform (digital) that directly relates to the number of turbine blades, gear teeth, etc. that have been sensed. These pulses, in turn, can be correlated to determine flow rate, RPM, or velocity.
• Non-Oriented Hall Effect Sensors – HN Series
  The HN series of speed sensors is based on Hall Effect sensor technology, which can sense a change in target motion from true zero to 20 KHz. These sensors incorporate a magnet within the sensor, enabling them to sense ferrous metal as well as magnetic targets. Maximum air gap sensing distances are typically 0.100″.

• Quadrature Output Dual Channel Speed Sensors – HD Series
  The HD series quadrature output sensors are based on Hall Effect sensor technology, which can sense a change in target motion from true zero to 15 KHz. The HD series offers dual channel output and, where required, directional logic. The output frequency of HD sensors has a square pulse waveform (digital) that directly relates to the number of turbine blades, gear teeth, etc. that have been sensed. These pulses, in turn, can be correlated to determine flow rate, RPM, or velocity.
