Hall Effect Crankshaft Signal SensorDesigned as a drop in sensor replacement for flying magnet crank trigger setups using a 16 threaded magnetic sensor. This sensor is a hall effect sensor, meaning it outputs a square wave signal, which is ideal for use with most electronic fuel injection systems. This sensor is to only be used with a trigger wheel with flying magnets. It does not detect a ferrous steel target. The sensor can operate from 5 20 volts. It is recommended to feed the sensor
