Standalone RFID Keypad for Homes and Offices

The B03 is a self-contained 125KHz RFID access control keypad that operates without a computer connection. It supports up to 1000 standard users and accepts EM cards, passwords, or a combination of both for entry. A built-in doorbell button adds convenience for visitors. This system suits households, hotels, offices, and apartments needing simple, standalone security.

Frequency Options and Environmental Limits

Buyers can choose between 125KHz or 13.56MHz operating frequencies to match existing credentials. The unit reads cards within a 0-10cm range and runs on a DC12V supply. It functions reliably across a -10 to +60°C temperature span and tolerates 20% to 90% relative humidity. These parameters define the practical installation envelope for indoor or sheltered outdoor use.

Plastic Housing with Surface Mounting

The controller uses a classical high-quality plastic shell measuring 120mm x 78mm x 22mm. Its compact footprint allows direct surface mounting on door frames or walls without bulky cut-outs. The material keeps weight low and resists everyday handling, while the keypad layout provides tactile feedback for code entry. No specialised tools are required for basic installation.

Questions about this item

Should I choose the 125KHz or 13.56MHz version for my existing cards?

Select 125KHz for EM cards or 13.56MHz for Mifare cards; the unit works on only one frequency so match your current credentials.

What does the 1000-user capacity mean for a small office?

You can register up to 1000 unique cards or PIN codes, enough for a growing team without re-enrolling users.

Does the DC12V input limit cable length or power options?

The lock requires a 12V DC supply; use a regulated adapter and keep cable runs short to avoid voltage drop at the reader.
