55075 Stainless Steel M12 Geartooth Speed Sensor
Description
The 55075 is a robust stainless steel hall effect barrel sensor with an M12 x
1mm pitch thread, 46mm (1.810”) long primarily for geartooth speed sensing.
It protects against severe and automotive environments and is capable of
switching up to 27Vdc and 20mA. It is available as three-wire (voltage output)
version with a range of sensitivity, cable length and connector options.It is
ideally suited to wheel, transmission and cam shaft speed sensing, geartooth
sensor, rotary encoders, industrial, commercial, and automotive applications.
