DJS-1 type speed sensorDetailed product description：

Detailed introduction:

1、 DJS-1 Speed Sensor Description:
The DJS-1 speed sensor is a type of sensor that has been used throughout the operation of diesel locomotives. When in use, it is connected to the measured shaft through a coupling. When the locomotive diesel engine drives the sensor to rotate, the sensor emits a three-phase AC voltage signal with a certain frequency, which is used for sampling by the locomotive electric speedometer, resistance braking, and locomotive monitoring device. The DJS-1 speed sensor has the characteristics of compact structure, beautiful appearance, safe use, reliability, and convenience.

2、 Main technical parameters of DJS-1 speed sensor:
1. Output voltage: The output voltage (AC RMS) of any two leads is linearly related to the rotational speed. When the rotational speed is 5000r/min, the output voltage is AC30V ± 0.5V.
2. Measurement range: 300~5000r/min
3. Output waveform: approximate sine wave
4. Output three-phase voltage balance rate: ≥ 93%
5. Insulation resistance:>20M Ω
6. Voltage endurance: AC1000V
7. Weight: 0.75KG
8. There is an M4 * 6 screw hole in the center of the pivot head

3、 Usage conditions for DJS-1 speed sensor:
1. Working temperature: -20~60 ℃
2. Humidity: ≤ 85%
3. Usage time: continuous
