The Magnetic Wheel Speed Sensor is designed to be mounted using a bracket (not supplied) and to sense a trigger magnet (included) as it rotates past. Suitable mounting positions may include the wheel, wheel hub, prop shaft or brake disc. Cable length approximately 1.7m’s

The Hall Effect Sensor is a non contact device that needs a metallic trigger to pass in front of it. Again, a bracket will usually need to be fabricated to mount the sensor in a suitable position. Please ensure that the distance between the sensor and trigger is in a 0.5 – 2.0 mm (0.007-0.07 inches) range.
