Pulse Sensor M12 Magnetic (3M)
This is exactly the same sensor as the other magnetic sensor but it has 3 Meter cable for easy installation.
The sensor is to generate a pulse for the tripmaster were there is no workable electronic pulse from the car or where you want to take a pulse from another (non-driven) wheel. The pulse sensor can be installed to detect metal that passes by the head of the sensor. The Magnetic sensor must be installed together with magnets. The benefit is that it can handle bigger distances from the magnet to the sensor (appr. to 5 mm) so it is easier to install than a metal sensor. Secondly it can handle very high frequencies so a high amount of pulses can be installed per revolution of the wheel.
This low-cost sensor is good to detect reliable up to 20 pulses in a wheel circumference (in 1 rotation of your wheel).This sensor can only detect a magnet in 1 direction (magnetic north or southpole). Please take care of this during installation!
