Standalone RFID Keypad for Doors

The YINGHUA B03 is a self-contained access control unit that reads 125KHz EM cards and accepts PIN codes. It supports up to 1000 users and operates on DC12V power without needing a computer connection. The keypad suits homes, offices, hotels and apartments where a simple, independent entry system is required.

Replaces Traditional Keyed Entry

This unit removes the need for physical keys by allowing entry via card, password or a combination of both. The upgrade is worthwhile when you want to manage access for many people without rekeying locks or issuing duplicate keys. A built-in doorbell button adds visitor signalling without extra wiring.

Check Voltage and Mounting Before Ordering

Verify that a DC12V supply is available at the installation point. Confirm the 120mm by 78mm by 22mm dimensions fit your door frame or mounting surface. The reader works at 125KHz or 13.56MHz frequency with a 0 to 10cm read range and operates from -10°C to +60°C in 20% to 90% humidity.

Questions about this item

What are the exact dimensions of the keypad unit for mounting?

The keypad measures 120 mm long, 78 mm wide and 22 mm deep, so the mounting surface must accommodate that footprint.

How do I wire the unit for power and the door strike, and what step is commonly missed?

Connect a DC 12 V supply to the power terminals and the electric strike to the relay output; the step often missed is adding a flyback diode across the strike coil to protect the relay.

How many EM cards can be enrolled before the internal memory is full?

The controller stores up to 1000 standard users; after that limit you must delete unused cards before enrolling new ones.
