HWBS-3 Brake Sensor

Category

HWBS-3(hidden wire brake sensor) is fitted onto your electric bike’s brake line and does not require specialized brake levers. The sensor operates with the contactless magnetic signal so it does not affect the physical operation of the brake. The integrated circuit inside the speed sensor contains a closed-loop control function which ensures signal stability even in extremely vibratory situations.

    SPECIFICATION FOR APPROVAL

    HWBS (Hidden Wire Brake Sensor) (VERSION): V2.0

    1. Function introduces

    HWBS is a brake sensor, that can be used on electric bicycles and electric motorcycles.

    The features of HWBS is, can use generic brakes, without the use of a special brake lever. The sensor installed on the soft shaft of the brake detects the movement of brake lines online. HWBS is a long life, small volume, free maintenance, micro-consumption electronic, low voltage power supply, and non-contact detection of magnetic sensors. Internal PLL circuits can ensure a stable output even use in vibration situations.
