RFID Metal Access Control for 4000 Users

This YINGHUA electric door lock combines an RFID reader with a metal touch keypad for keyless entry. It accepts both ID cards at 125 kHz and IC cards at 13.56 MHz, giving administrators flexibility in credential choice. The system stores up to 4000 users, making it suitable for offices, apartments or secure facilities. A magnetic controller manages the locking mechanism for reliable daily operation.

DC12V Operation with Low Current Draw

The unit runs on a 12 V DC supply and draws minimal current during standby and active unlocking. This low power requirement keeps heat generation negligible, so the metal housing stays cool to the touch even with continuous use. No cooling fan is present, ensuring completely silent operation in quiet hallways or residential corridors. The waterproof construction protects the electronics from moisture without adding thermal load.

Questions about this item

How do I wire the DC12V supply to the magnetic controller and what polarity mistake should I avoid?

Connect the 12 V DC source to the controller terminals matching positive to positive and negative to negative; reversing the polarity will prevent the lock from operating.

How many credential slots remain after enrolling 4000 users and when must the database be cleared?

The unit stores up to 4000 users; once that limit is reached you must delete existing entries before adding new cards or codes.
