YD69 CW/CCW Measurement Dual-Channel Hall Effect Rotation Speed Sensor

YD69 CW/CCW Measurement Dual-Channel Hall Effect Rotation Speed Sensor

A. Technical Parameters

(The parameters of phase difference is the data when the speed gear modulus is 2,  in line with DIN867 standard.)

1. Installation

a. The measured machine need to be a magnetizer with raised parts or concave slots.

Suggestion: modulus ≥1.7, the material need to be magnetic low-carbon steel.

P.S.: If the width of the raised part or concave slots is different from the width of the flat surface, the waveform width will be affected.

b. Installation gap: 0.3-1 .5 mm, typical value is 1.0mm.

P.S.: Depends on the vibration of measured machine.

2. Output Characteristics

a. Frequency response characteristics: 0 ~ 20 kHz

b. Output channels: Double channel

c. Output waveform: square wave, rise and fall by time  12 u s + 40%

d. Output amplitude:

high level: U b-(1.8 V + 40%); low level: < 2.2 V

e. Pulse duty cycle: 50%±25%

f. Phase difference: 90±30°

P.S.: Depends on the Installation and the rotation direction of rotating parts. This parameter is suitable for the installation on the figure 4 of the manual.

g. Load capacity: ±20mA (Maximum)

h. Output impedance: <47Ω

3. Work environment requirements

a. Working power supply: U b=15VDC±30% (8V~28V)

b. Current consumption: ≤35mA

c. Working temperature: -40°C~125°C (head)

d. Vibration resistance performance: vibration (10Hz ~ 2KHz) 30g, shock 100g

e. Sealing: IP6813.

4. Electrical characteristics

a. Power source polarity protection: yes

b. Output short circuit protection: yes

c. Insulating strength: 1000V 50Hz,1min ( channel and shell)

5. External cable and connection

The wire attached: 6 × 0.5mm2 shielded cable, standard length is 1.0 meter (can be extended according to user’s requirements)

B. Installation, Usage and Fault handling

1. About SJ series Hall Dual-Channel Sensor, it is not allowed the working power supply connect with locomotive battery, it should connect with isolated power supply to output

2. The sensor output wire must be connected with no mistake according to the specification, make sure there is no short circuit and open circuit appears. Strictly prohibit pulse output and power supply to be short circuit.

3. Install the sensor according to the instructions in the installation diagram.  After adjust the gap between the gear and head of sensor to 0.6mm, tighten it.

4. Before the sensor installed into the shell of measured machine, use a ferromagnetic contacts and leaves the sensor, if the output current changes, it is normal.

5. In normal condition, if the output current no changes, the sensor is damaged.

6. If the wire is damaged by external force, the solution is to change a sensor.
