1 General description of the door-handle
The Door-Handle HUF14632 with NFC is equipped with sensors that enables users of a car with passive
entry system to lock/unlock the doors by carrying the key fob or an authorised NFC-Device with them.
NFC-Antenna
Unlock/Lock
NFC-Reader:
When an NFC-Device approaches to the NFC-Antenna, the door handle sends a signal to the electronic
control unit to initiate the authorisation sequence for unlocking or locking the door.
