China Suppliers Factory CRT-NH100 Smart NFC Cylinder Lock for Secure Access Management in Industrial Facilities

This lock adopts advanced NFC energy harvesting technology, which extracts power directly from mobile phones during unlocking. No built-in batteries, no wiring layout, and no regular battery replacement. It radically cuts the long-term operation and maintenance costs for scattered field equipment in telecom and power industries, especially suitable for remote sites that are difficult to reach. The operating current is lower than 100mA, ensuring stable and energy-saving operation.

The lock cylinder is equipped with a built-in storage module that records up to 500 operation logs, covering unlocking, locking, patrol inspection and other behaviors. All operation records form an irreversible audit trail, realizing whole-process traceability of personnel access. Enterprises can customize access permissions for different maintenance staff, effectively preventing unauthorized access to core equipment, standardizing on-site operation procedures, and simplifying asset security management.

We adopt China national cryptographic standard SM4 encryption algorithm for data transmission and identity verification, which fully resists signal interception and cracking. The main body is made of 304 stainless steel, with strong resistance to prying, smashing and other violent attacks. With an IP65 protection grade, it is dust-proof and water-resistant. It can work normally in the temperature range of -40℃ ~ 80℃ and humidity of 20%~98% RH, adapting to wind, rain, frost and other harsh outdoor environments all year round.

The 13.56MHz standard NFC technology supports a touch distance within 1cm. Maintenance personnel only need to attach the mobile phone NFC area to the lock, and the whole unlocking process can be completed within 2 seconds. The operation is simple and efficient, which greatly saves the working time of front-line staff and improves the overall operation efficiency of telecom base stations and power facilities. The mechanical structure supports more than 20,000 switch cycles, with long service life and high reliability.
