ISSUE 1 Installation Instructions for the SNDH-H Series Hall-Effect Speed Sensor GENERAL INFORMATION The SNDH-H Series Hall-Effect Speed Sensors use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets. Optimum performance is dependent upon variables which must be considered in combination: target material, geometry and speed, sensor/target gap, and environmental temperature. 50071164 INSTALLATION Mount sensor so that the center of the sensor face is over the center of the gear teeth or target. Ensure the mounted sensor is stable and vibration free. Locate sensor wires as far as possible from electrical motors, relays, etc. Do not run sensor wires in parallel with power cables. Table 1.
