Smart Electronic U-Type Lock U01
The Vanma WM-2000C-U01 is a heavy-duty passive electronic U-lock (shackle lock) designed for high-security applications where traditional cable or padlocks lack the necessary physical strength. Combining a thick, cut-resistant shackle with Vanma’s battery-free smart technology, the U01 is the ultimate solution for securing gates, motorcycles, utility meters, and warehouse doors in remote or harsh environments.

Features
- Passive Electronic Core: The U01 contains no internal battery. It is energized instantly by the Vanma Smart Key upon contact. This ensures the lock is always ready for use, even after years of being left in a remote location, without the need for charging or battery swaps.
- High-Strength Physical Barrier: Constructed with a reinforced steel shackle, the U-Type design offers superior resistance against bolt cutters, saws, and prying tools compared to standard padlocks.
- Full Audit Accountability: Every time the lock is opened, it logs the unique ID of the smart key and the exact timestamp. This data provides a 100% verifiable record of who accessed the asset, which is essential for industrial and commercial compliance.
- Pick-Proof Design: Because there is no traditional keyhole, the U01 is immune to lock-picking, bumping, and master-keying attacks. It utilizes AES256 encryption for all data exchanges between the lock and the key.
- IP68 Weather Resistance: Built for the outdoors, the U01 is completely waterproof and dustproof. It is engineered to withstand extreme temperatures (-40°C to +70°C) and corrosive environments.
- Centralized Management: Administrators can use the Vanma software to grant temporary access, set specific time windows for contractors, or instantly blacklist lost keys.
