High-sensitivity & Low-power Induction Coil Custom Solution for Smart Door Locks

Smart door locks and access control systems rely on miniature induction coils to realize card recognition, Bluetooth wake-up and low-power standby functions. Operating in all-weather outdoor and indoor environments with temperature alternation, static interference and humidity changes, smart locks require supporting coils to have low power consumption, high induction sensitivity and excellent temperature stability. Ordinary coils suffer from high standby power loss, delayed induction and serious temperature drift, causing unlock failure, rapid power consumption and false trigger problems, which seriously affect user experience and product after-sales quality.

Our client is a leading domestic smart security brand, specializing in R&D and mass production of smart door locks and access control systems, with products sold at home and abroad. The original coils had excessive power consumption and poor low-temperature adaptability, resulting in short battery life and high unlock failure rate. The client needed customized low-power induction coils with fast response, wide temperature stability and strong anti-interference performance to improve product durability and user experience.

Fuying Electronics adopts low-loss and high magnetic stability enameled wire to reduce standby power consumption and extend equipment battery life. The precision equidistant winding process optimizes electromagnetic induction coverage to realize millisecond-level fast recognition without delay. Optimized temperature drift coefficient design ensures stable performance in -30℃~70℃ wide temperature range. The additional electrostatic shielding structure resists static and electromagnetic interference to eliminate false trigger and recognition disorder. All coils pass strict power consumption, temperature durability and sensitivity calibration tests to ensure batch consistency.

After mass application, the client’s smart locks achieve fast and accurate unlocking with zero failure in complex environments, and the overall battery life is increased by more than 30%. The product after-sales failure rate is greatly reduced, fully meeting domestic and foreign security certification standards and project delivery requirements. Fuying Electronics provides low-power, high-sensitivity and high-stability customized coils for various smart security terminal devices.
