This sensor is designed to trigger from a ferrous metal (magnetic steel) target, such as Holley's 60-2 crank trigger wheels. It can also be used for a cam sensor trigger and other applications.BrandHolley EFIEmission Code5Product TypeHall Effect SensorPart Number554-117..

P/N 554-118 is designed as a drop-in sensor replacement for flying magnet crank trigger setups using a 3/4-16" 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...
