► Core technology advantages

1. PEPS  has more powerful system functions: automatic door unlocking (PKE), the owner only needs to carry the key within the sensing range and press the start button to start the engine (PKG). When the key is out of power, there is still a way to start the engine (IMMO), just touch the key to the door handle sensing area to unlock.

2. The NJJ29C2 series at the base station end mainly improves the LF drive current (2.5A Peak Current in High-power-driver mode), selectable LF channels (the number of LF channels is divided into 5, 7, and 9 according to the different suffixes), and supports two-way IMMO.

3. The key end NCF29A1 has excellent LF (low frequency) sensitivity and low power consumption to achieve the longest battery life.

4. The receiving end NCK2912 has excellent RF performance.
