YINGHUA RFID/EM Keypad Door Lock 13.56 MHz 1000 User

Standalone Access Controller

The YINGHUA RFID/EM keypad operates on 12 V DC and supports up to 1000 users with offline data protection. It accepts EM, ID and IC cards at 125 kHz or 13.56 MHz frequencies. A 5 to 15 mm read range allows quick entry via card, PIN or both combined. Master cards simplify enrolment without a connected PC.

Replaces Keyed Entry Systems

The unit removes the need for physical keys and re-keying when staff change. Adding or revoking credentials takes seconds at the keypad rather than waiting for a locksmith. The jump is worth it when a site manages dozens of users and needs audit-free access changes. It also integrates with an existing door bell circuit for visitor release.

Sustained Operation Behaviour

Continuous operation draws 0.1 A when the lock actuates and returns to idle instantly. Stored user data survives power loss without batteries or cloud sync. The metal housing resists daily handling in indoor or sheltered outdoor positions. No active cooling is required, so silent reliability is maintained across repeated cycles.
