Magnetic Hall Effect Sensors: DH Series

Brand: AI-Tek Instruments LLC

The experts at AI-Tek have been designing and manufacturing Hall Effect sensors for harsh applications for over sixty years.

With a dedication to providing reliable and accurate sensors, the DH Series product line is developed specifically for the industrial, rail, military and automotive industries.

DH speed sensors can sense each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to target speed.

Each time a gear tooth (or any ferrous discontinuity) passes in front of the sensor the output changes state.

This unique combination of differential sensing technology and calibration makes these sensors highly tolerant of installation misalignment, target geometry and composition, target run-out, vibration and air gap changes.
