RFID EMID 125KHz Electric Lock Access Control Module DC12V
RFID EMID 125KHz Electric Lock Access Control Module DC12V
SARY EMID 125KHz RFID Embedded Induction Electric Lock Control Module
The SARY SY-1788 RFID Access Control Board is a compact, embedded induction control module designed for seamless integration into lockers, jewelry display drawers, wardrobes, cabinet doors, and other access-controlled enclosures. Operating at the widely compatible 125KHz EMID frequency, this board delivers reliable keycard-based access with a DC12V normally-open output — perfect for controlling low-voltage electric locks in residential, retail, and light commercial settings.
With support for up to 2,000 registered cards, this module is ideal for multi-user environments where individual access credentials need to be managed efficiently. Its slim 63×33mm footprint allows for easy hidden installation inside drawer cavities, door frames, or custom enclosures. Simply tap any registered EMID card to trigger the lock mechanism — no keys, no keypads.

Frequently Asked Questions
Q: What type of cards are compatible with the SARY SY-1788 RFID access control module?
A: The SY-1788 operates at 125KHz and is compatible with standard EMID format cards and key fobs, including EM4100 and EM4200 type credentials. It does not support 13.56MHz cards (such as MIFARE or HID iCLASS).
Q: How many cards can be stored on the SY-1788 control board?
A: The module supports a storage capacity of up to 2,000 registered cards, making it well-suited for shared-use lockers, retail display cases, and other multi-user environments.
Q: What kind of electric lock does this module work with?
A: The SY-1788 features a normally-open DC 12V output with a rated load of less than 3A. It is compatible with most standard 12V electric bolt locks, electric strike locks, and solenoid-based cabinet locks that operate on a normally-open circuit.
Q: Is the antenna built into the board, or do I need an external reader?
A: The induction antenna is embedded directly onto the control board, so no separate external card reader is required. The compact 63×33mm board can be mounted discreetly inside a drawer panel or door frame for a clean, hidden installation.
Q: What is the working voltage for this RFID control board?
A: The board requires a DC 12V power supply. Ensure your power source can deliver stable 12V DC current to guarantee consistent and reliable operation of both the control module and the connected electric lock.
