YD62 Hall effect rotation speed sensor

Brief Introduction

YD62 hall effect speed sensor adopts hall effect when the metal tooth go through the front end of the hall 
sensor, causing the magnetic field changes,  the hall element detect this changes and converted into a 
alternating electric signal, the built in circuit of sensor amplifies the signal, shaping, output good rectangular
 pulse signal, measuring  frequency range more range.

The output signal more accurate and stable, easy installation, prevent oil and waterproof, have been 
widely used in the field of power , automotive, aviation, textiles and petrochemicals guns.

Technical parameters

Gear speed

The teeth using metallic material with big permeability such as 45 steel, toothed is involute 

tooth, the teeth gap and tooth width have great impact on the speed measurement, 

when teeth gap is too small,may result in the sensor no output, and seriously affect the 

measurement, therefore teeth processing according to request.

Installation 

Sensor installation pls refer to figure2, a magnetically permeable material(such as iron, steel,ect)

as teeth installed in the measured shaft.The gear be processed to involute teeth, the modulus 

will larger than 2. Hall sensor, reluctance sensor, eddy current sensor mounted the bracket, 

radially aligned with the gear, installation gap between0.5~2mm, sensor signal output cable are 

3 cores shielding line, lead wire refer to figure2.
