DH-SENSOR with double halls in the housing can detect the cycling of the bike. It can be installed on both sides of the E-bike, the program is different, the function is same, so please inform us which side you will install on when you order. Compared with SH-SENSOR, DH-SENSOR equipped with 12 magnets offers higher accuracy and further detection distance which can reach 6 mm. The detection distance of SH-SENSOR equipped with 5 magnets is only 3 mm. DH-SENSOR can distinguish the direction of pedals.
In the sensitivity, DH-SENSOR is 2-3 times than SH-SENSOR, and no error action. When go ahead, the sensor outputs pulse signal and the indicator light will flash correspondingly. When pedal go back, the sensor will only output low potential, thus there is no pulse signal, the indicator light doesn’t work. It’s convenient of detecting the sensor works well or not by the customer
