The inductive proximity sensor can be used as an alternative speedometer sensor on all our instruments. It does NOT require magnets for pulse pick-up and is normally directed at sufficiently large, rotating metal parts. Depending on the motorcycle, it is more demanding to adjust than e.g. a reed contact.Note: This is a MINUS-ACTIVE sensor and is used on the current instruments. Please check your operating instructions to see whether your instrument expects a MINUS/MASS signal. If you are looking for a replacement for such a sensor, DW-AD-621-M5 NPN should be on the cable.
