RFID Access Control System

The YINGHUA RFID access control door lock provides keyless entry for homes and offices using proximity cards or a personal PIN. It supports up to 500 registered cards, each paired with an individual code for managed access. The unit operates on a DC 12V supply and includes a doorbell function for visitor notification. Admin settings allow three unlock modes: card and password together, card only, or password only.

Capacity and Headroom

The system stores credentials for 500 cards, giving ample headroom for a small business or large household. Each card carries its own PIN, so access rights stay separate without extra hardware. The relay holds the lock open for three seconds per valid entry, which suits standard traffic flow. At the 500-card limit, new users cannot be enrolled until existing records are removed.

Interface Practical Limits

Cards must be EM or EM-compatible types and read reliably between 5 mm and 50 mm from the reader surface. The device functions across a -10 °C to 70 °C temperature range, covering most indoor and sheltered outdoor installations. Mounting dimensions are 11.8 cm by 11.8 cm by 2.3 cm, requiring a flat surface of that footprint. An optional waterproof cover extends outdoor durability where direct exposure occurs.

Questions about this item

Will the 12 V DC lock relay work with my existing 12 V power supply?

The unit requires a 12 V DC supply and its lock relay activates for 3 seconds, so any regulated 12 V source that can deliver the relay current will operate it.

How can I confirm the reader is functioning after wiring it up?

Present an EM card within 5 to 50 mm; a valid card triggers the relay and the door bell option sounds, showing the system is reading correctly.

Does the box include the 10 cards, 10 key tags and waterproof cover shown in the list?

Those three items are marked optional; the standard package contains the control unit, English manual and one screw pack only.
