Standalone RFID Door Access Keypad

This YINGHUA B03 unit provides keyless entry using 125KHz RFID cards or a numeric PIN for up to 1000 users. It operates independently without a computer connection, making it suitable for homes, offices, and apartments. The device includes five blue proximity keys and features a built-in doorbell button.

Check Power Supply and Mounting Space

Verify that a DC12V power source is available at the installation location before ordering. The keypad measures 120mm by 78mm by 22mm, so confirm the mounting surface accommodates these dimensions. Ensure the operating environment stays within the -10°C to +60°C temperature range and 20% to 90% humidity limits.

Low Power Consumption and Silent Operation

The unit draws minimal working current at DC12V, contributing to low heat output during continuous use. With no moving mechanical parts or cooling fans, it runs silently in normal operation. The RFID reader activates only when a card is presented within 0 to 10cm, further reducing average power draw.

Questions about this item

Does the YINGHUA B03 keypad come with the five blue RFID keys included, or must they be ordered separately?

The listing includes the B03 access-control keypad and five blue 125KHz EM cards; no extra keys are required for basic operation.

Should I select the 125KHz or 13.56 MHz frequency version for standard EM cards?

Choose the 125KHz option; the five supplied blue keys operate at that frequency and the reader is set for EM card compatibility.

How far from the reader will the supplied blue keys actually work?

The reader detects cards at 0-10 cm, so present each key within about one centimetre of the panel for reliable unlocking.
