RFID proximity door lock for home and office

The YINGHUA RFID proximity door lock provides keyless entry for residential and commercial doors. It operates on a 12 V DC supply and supports both EM and EM-compatible cards at 125 kHz. The unit reads cards from 5 to 50 mm away and stores up to 500 unique cards each paired with a personal PIN.

Ten RFID cards and mounting hardware included

The package supplies ten 125 kHz RFID cards so access can be granted immediately after installation. An English user manual and a screw pack are also provided for straightforward setup. No additional credentials or software licences are required to begin using the system.

Handles 500 users with selectable entry modes

The controller manages up to 500 card holders and offers three admin-selectable unlock methods: card and password together, card only, or password only. A door-bell function is built in and the lock relay activates for three seconds. Operating temperature ranges from -10 °C to 70 °C.

Questions about this item

What maintenance or replacement will the 125 kHz RFID cards need over time?

The system supports up to 500 cards; each card carries a personal PIN. Replace lost or damaged cards with compatible EM-type 125 kHz tags and re-enrol them using the admin menu.

Which limit appears first during continuous operation — the card capacity or the relay duty cycle?

The 500-card database limit is reached long before the 3-second relay cycle becomes a constraint; the lock relay simply pulses for three seconds per valid entry.

How much heat or power does the unit draw when running all day on 12 V DC?

Operating voltage is 12 V DC and the working temperature range is -10 to 70 °C; the device is designed for continuous indoor or outdoor use within that range.
