Following the successful launch of ZMT-20, the world's first battery-free smart keyless manhole lock, Hizima adheres to the same core design concept of “environmentally friendly and maintenance-free”. In August 2025, it officially released the first version of the GEN Smart Padlock ZMP-51 and NFC Smart Padlock ZMP-52, providing more efficient and sustainable smart solutions for outdoor security scenarios.

As new members of Hizima's battery-free smart lock series, ZMP-51 and ZMP-52 inherit the core advantages of the Hizima brand in the field of power-free lock technology:

• Power-Free Operation & Maintenance-Free Convenience: Neither of the two products requires battery installation or external power supply. ZMP-51 is equipped with power-generation energy harvesting technology, while ZMP-52 integrates NFC (Near Field Communication) near-field energy harvesting technology. This fundamentally addresses the pain points of traditional locks, such as frequent battery replacement and high maintenance costs, and significantly reduces long-term usage costs.
• Easy Operation & Rapid Deployment: With a lightweight design, the products feature a simple installation process that requires no complex construction, allowing quick adaptation to various outdoor application scenarios.
• High Protection, Durability & Extreme Environment Adaptability: Based on strict industrial-grade quality standards, the products possess excellent resistance to high and low temperatures, corrosion, and impact. They can stably withstand harsh outdoor natural environments such as heavy rain, intense sunlight, and sandstorms.
• Enhanced Security & Intelligent Control: The new mechanical design structure greatly improves the anti-violent opening performance, and energy harvesting (ZMP-51 leverages power-generation technology, while ZMP-52 uses NFC near-field technology) and identity verification are realized simultaneously during the unlocking process.
