China Suppliers CRT-NH100 Smart NFC Cylinder Lock - Secure Access Solution for Industrial Facilities from Factory
Digital Traceable Locking Solution for Telecom & Power Critical Infrastructure
As core foundations of social operation, telecommunications and power industries have a large number of distributed outdoor equipment such as base station cabinets, power substations, distribution boxes and remote control cabinets. Traditional mechanical locks suffer from key management chaos, untraceable access records, poor anti-theft performance and frequent maintenance troubles. Our CRT-NH100 Smart NFC Cylinder Lock is designed to solve these pain points, bringing intelligent, secure and traceable access management to industrial facilities.
Core Industrial Advantages
1. Battery-Free Passive Design, Zero Maintenance
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.
2. Full Traceable Management & Custom Permission Control
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.
3. Military-Grade Security & Outstanding Environmental Adaptability
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.
4. Fast & Efficient Operation for Field Work
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.
