Guangzhou DC 8V-24V Hall Switch Sensor
Specifications
Size: 79mm43mm26mm
Net weight: 79.5g
Wiring Connection
Please connect the wiring as labeled on the product:
- The long black wire is connected to the negative pole of the power supply.
- The long red wire is connected to the positive pole of the power supply.
- The short black wire, short brown wire, and short blue wire are respectively connected to the corresponding wires of the same color of the Hall switch.
Installation
The Hall switch needs to be fixed firmly with a bracket. The installation distance between the Hall switch and the magnet must be within 10mm (the effective distance is subject to the detected magnet). The magnet has N/S sides, only one side is valid.
Precautions for Use
- Avoid strong electromagnetic interference by using shielded wire or twisted-pair wire for measuring wire.
- Avoid installing magnets on metallic iron materials as they will interfere with Hall’s detection.
- The Hall switch and magnet need to be fixed firmly during detection to prevent data inaccuracies.
- Use NPN normally open sensors for proper functioning.
FAQ
Common Problems and Solutions
| Problem | Cause | Solution |
|---|---|---|
| The meter is not connected to the Hall switch. | – | Install the Hall switch and |
magnet in the correct way.
The meter is connected to the Hall switch, but the magnet is
not detected.| Magnet not installed, or distance too far, misalignment.|
Detect within the product range, ensure correct
installation.
The actual speed is too low.| Issue with Hall switch.| Replace with a NPN
normally open sensor.
The environment interferes with Hall switch detection.| Use environment
interferes with Hall switch detection (e.g.,
inverter).| Use anti-jamming Hall sensor with shielded wire.
The actual speed is too high.| Environment interferes with Hall switch
detection.| Use anti-jamming Hall sensor with shielded wire.
The Hall switch or magnet is not firmly fixed.| –| Ensure firm fixation during
detection.

PRECAUTIONS FOR USE
- Should avoid strong electromagnetic interference, it is better to use shielded wire or twisted-pair wire for measuring wire. Avoid the same tube or twisted wiring with other such as strong current wires or power wires to avoid unnecessary interference.
- The matching Hall switch is an NPN normally open type with a diameter of 12mm. Customers can purchase other NPN normally open sensors instead
- The Hall switch and magnet need to be fixed firmly during detection, otherwise the shaking of the Hall switch or magnet will cause the detection data to jump or be inaccurate. The installation distance between the Hall switch and the magnet must be within 10mm.
- Magnets cannot be installed on metallic iron materials, as metallic materials will interfere with Hall’s detection. The magnet has N/S sides, only one side can be detected. When the Hall detects the magnet, the Hall lamp will flash.
Common problems and solutions for product use
| Problem | Cause | Solution |
|---|---|---|
| Displys “LLLL” | The meter is not connected to the Hall switch. |
Install the Hall switch and magnet in the correct way.
The meter is connected to the Hall switch, but the magnet is not detected.(maybe the magnet is not installed, or the distance between the Hall and the magnet is too far; Or the magnet and
the Hall switch are not aligned, etc.)
The actual speed is too low.| Detect within the product range
There is a problem with the Hall switch.| Replace a NPN normally open sensor
Use environment interferes with Hall switch detection. (such as inverter)| Use
the anti-jamming Hall sensor with shielded wire, and connect the shielded wire
with the negative wire of Hall signal.
Displays “HHHH”| The environment interferes with the Hall switch detection.
(for example, Frequency converter)
The actual speed is too high.| Detect within the product range
Displays to jump or be inaccurate| The environment interferes with the Hall
switch detection. (for example, Frequency converter)| Use the anti-jamming
Hall sensor with shielded wire, and connect the shielded wire with the
negative wire of Hall signal.
The Hall switch or magnet is not firmly fixed.
