Flange Mount Geartooth > 55505
55505 Hall Effect Flange Mount Geartooth Speed Sensor
Description
The 55505 is a robust flange mounting hall effect sensor primarily for geartooth
speed sensing. Protected against severe and automotive environments. It is
capable of switching up to 27Vdc and 20mA and available as three-wire (voltage
output) version. It’s case design encorporates brass mounting bush. It is ideally
suited to wheel, transmission and camshaft speed sensing, geartooth sensor,
rotary encoders, industrial, commercial, and automotive applications.
