- Commodity name: HD-M18 Series
- 产品特点及应用: • Employs the Hall principle—non-contact, wear-free, and offering an extended service life <br/> • A single magnetic steel is enough to identify forward and reverse rotation, making installation simple. <br/> • Wide detection range, high fault tolerance <br/> • Independent green/yellow line-level outputs, making direction status instantly clear
• Employs the Hall principle for non-contact, wear-free operation with an extended lifespan • A single magnet is sufficient to detect both forward and reverse rotation, making installation effortless
Technical specifications
Operating Voltage
DC 5V–36V
Output method
Open-collector output (customizable NPN or PNP type)
Probe detection distance
Recommended spacing: 5–20 mm
Work environment
Temperature: -20°C to +80°C, Humidity: 90%
Signal Status
Red line: Vcc / Black line, Shielding wire: GND / Yellow line: Vout 1 / Green line: Vout 2
The direction of the arrow marked on the sensing surface of the magnet and the Hall speed sensor must align for forward rotation; otherwise, it indicates reverse rotation. When power is applied, the yellow and green wires carry a high signal.
When rotating clockwise, the yellow line is low, while the green line is high.
When reversing, the yellow line indicates high, and the green line indicates low;
When rotation stops or exceeds 60 seconds per revolution, the signal output remains high.
Delay time
60s (customizable based on customer needs)
LED
Red / Green
Protection Level
IP65
Vibration resistance capability
5G under normal usage conditions
Shell material
Nickel-plated brass
Connection method
1m cable
Output characteristics
Accessory Description
1. Forward/Reverse Sensor: 1 set;
2. Neodymium iron boron strong magnet: 1 piece;
3. Mounting brackets: 1 set.
Important Notes
1. The supply voltage must not exceed the specified range, as this could lead to damage of critical components;
2. The recommended installation distance between the sensor probe and the magnet is 5–20 mm;
3. Do not use the proximity switch in a DC magnetic field exceeding 200 Gauss, as this may lead to malfunction;
4. When routing cables, make sure to avoid moving vehicle parts and areas with significant heat generation as much as possible; ensure that the wiring is securely bundled.
5. Power cable: Ensure wiring is connected strictly according to the instructions. When connecting the sensor's four-core cable to the vehicle's positive power terminal, always include a 0.2 A fuse first (to prevent short circuits and damage to the original wiring). Connect the signal wire afterward.
