Honeywell 1gt101dc or Littelfuse 55505.
Do you know any partnumber or oem reference? in my country can´t find similar, and my dyno is stopped by this sensor 🙁
No, there are probably equivalent sensors, but I don't know. Better search for hall effect sensors that have a NPN output and can run on minimum 4.5V. Make sure to use a shielded cable.
