Working Principle:
Before using make sure the gear is mounted on the shaft for speed measurement traight, Helical or Grooved disk gear all can be used ount the sensor on the bracket, Adjust the Clarence between the sensor and the gear tooth to be approx. 1mm. When the gear starts rotating with the shaft, According to the principle of electromagnetic induction, a voltage pulse signal is generated at both ends of the internal coil of the sensor, The Z-voltage pulse signal is generated when the axis is rotated, According to the type. flush
Given that NPN= Measured shaft speed in Rotation/Minute, Z=ber of gear teeth.
When the gear tooth number is 60, the rotation of the axis is converted to a voltage pulse signal with frequency of f, and the signal is sent to the corresponding digital speed.
Features:
1) Digital Output Signal
2) Gear Tooth Sensing Capability
3) No Rotary Orientation Concerns
4) Operation Temperature from –30°C to 125°C
5) Short Circuit Protection
6) Zero Speed Operation
7) High Speed (15kHz) Operation
8) 12-36 VDC Operation
9) Nickel plated, Brass housing
