The growth over the next five years will mainly rely on technological upgrades and expansion of application scenarios:
Hitching a ride on the smart home train: The door magnet is the foundation for the “perception” function of the smart refrigerator. The high-end refrigerators’ demand for Hall chips and low-power Bluetooth/Wi-Fi modules has made the switch no longer just a few dollars’ worth of component.
Achieving functional premium: Combined with algorithms, it can realize remote alarms, automatic replenishment, and even health management. The added value of such modules is much higher than that of traditional mechanical switches.
Penetrating commercial scenarios: In scenarios such as medical cold storage cabinets and fresh food cabinets, the door magnet is a necessary safety monitoring component. This market has higher requirements for reliability and certification, and offers greater profit margins.
Core competitive advantage
As a manufacturer, you can build the following moats:
Technical stability: Ensure resistance to vibration (the Hall scheme is superior to the reed switch) and anti-interference capabilities. This is a crucial requirement for entering the supply chain of major brands.
Customization capability: Customize the outer shell, cable length, and even provide composite modules integrated with temperature and humidity sensors according to different refrigerator structures, which can significantly increase customer loyalty.
Cost and response advantages: Compared to foreign sensor giants, local manufacturers possess the ability for rapid response and cost control. This is particularly important in the fierce competition.
