Speed Sensor Hall-Effect HA-M

 Max. frequency: ≤ 4.2 kHz
 Air gap: 0.5 to 1.0 mm
 Bore diameter: 11.8 mm
 Max. vibration: 1,200 m/s² at 10 Hz to 2 kHz
 Weight w/o wire: 12 g

This sensor is designed for incremental measurement of rotational speed (e.g. camshaft, crankshaft
or wheel speed).
Due to the rotation of a ferromagnetic target wheel
in front of the HA-M, the magnetic field is modulated
at the place of the Hall probe. A Hall-effect sensorelement with integrated signal conditioning circuit
detects this change and generates a digital output
signal. We offer this sensor with two different typesof output: Active high and Active low.
The main feature and benefit of this sensor is thecombination of a high quality production part androbust design with metal housing and motorsport
connectors.

For mounting please use only the integrated plug.
If a wheel with different dimensions is used (see Environment),
the technical function has to be tested individually.
Please ensure that the environmental conditions do not exceed
the sensor specifications.
