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
1. Operating Voltage Range: 5~ 24V ( DC )
2. Signal frequency: 0~20KHz
3. Module of gear: m2~4(involute gear)
4. Output signal: square wave, the peak-peak value equal to the the amplitude of voltage,
unrelated to speed, maximum output current 20mA,
5. Operating temperature: -3~+120°C
6. Thread specification: refer to selection guide
7. Teeth gap: 1~2mm
8. Weight: about 120g

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.
