Feature:1. Dual Hall Sensors: The electric bicycle assist sensor housing has dual Hall sensors to detect the riding of the bicycle.2. 12 Magnets: With 12 magnets, the accuracy will be higher than with 5 magnets, and the distance from the sensor will be longer. In terms of sensitivity, it is 23 times that of ordinary 5 magnets, and there is no wrong action.3. Pulse Signal: Installed on the right side of the pedal by default, with 12 pulses in a circle. The chip screens and identifies the pulse signal to determine the rotation direction. The forward direction is valid, and the reverse direction is invalid.4. LED: When the pedal moves forward, the sensor will output a pulse signal, and the LED is at a low level (with or without a pulse signal), so the LED will not flash.5. Characteristics: Made of high quality material, strong and durable. Professional manufacture, stable performance and high reliability. Easy installation and disassembly, waterproof interface.Specification:Item Type: Electric Bicycle Assist SensorMaterial: PC PlasticHall Electrical Life: >20M timesNo Braking Current: < 5mAWith Braking Current: < 6mAInsulation Dry Condition: > 20M ohmInsulation Wet Conditions: > 2M ohmBraking Corresponding Time: <0.001SCorresponding Distance: 2-3mm .Package List:1 x Sensor Wiring1 x Sensor Sheet
