GTN Series Hall Effect Gear Tooth Sensors use a magnetically biased Hall effect integrated circuit to accurately sense movement of ferrous metal targets. This specially designed I.C., with discrete capacitor and bias magnet, together with protection and diagnostics circuitry, is sealed in a probe type package for physical protection and cost effective installation.
Output is digital, current sinking (open Collector). Reverse polarity protection is standard. If power is inadvertently wired backwards, the sensor will not be damaged.
An integrated electronic diagnostics feature enables detection of open or short circuits in the power supply line by monitoring levels in the sensor output.
Optimum sensor performance is dependent on the following variables which must be considered in combination: - Target material, geometry, and speed
- Sensor/target gap
- Ambient temperature
- Magnetic material in close proximity
