Magnetic speed sensor-Dual-channel speed sensor-VS-4133-052 series
I. Description
The VS-4133-052 speed sensor is used in conjunction with the pole wheel and is suitable for generating square wave signals proportional to the rotational speed. They have static behavior, that is, to ensure that the speed of pulse generation is as low as the speed corresponding to the frequency of 0 Hz. The monitoring components are composed of magnetically biased differential Hall effect semiconductors. The internal two-channel structure requires that the sensor must face. The sensor has a flange for correct installation.
II. Characteristics
11.1 to 2 channels can also be used as output signals for electrical isolation systems
2. Inverting output signal of square wave signal with current or voltage output (optional)
3. Output static voltage (optional) Enclosure protection grade IP 68 type
4. Due to the non-contact measurement of rotational motion, maintenance and wear-free operation can be achieved
5. Safely collect crawling movements without losing pulses and achieve rapid rotational movements
6. The current output signal is not affected by electromagnetic interference fields and comes with a reverse signal, which can be used for 7. Decouple the interfering signal
8. Cable breakage monitoring is carried out through current output or voltage output (with static voltage)
III. Application
11. Rotational speed acquisition for traction force monitoring
2. Speed collection for wheel slip protection
3. Speed collection for bogie monitoring
4. Speed collection for automatic train protection

|
Duty cycle |
50% (40-60%) depends on the rotation direction, air gap and tooth design. The phase shift between the position edge and the negative edge of the output signal is usually not equal in magnitude and depends on the duty cycle. However, always ensure the correct operation of the subsequent rotation direction discriminator. The output has short-circuit protection function and reverse polarity protection function. |
