Model WG26 output RFID reader module for ID EM4100 cards Key benefits Fast, reliable reading: reads compatible 125 kHz ID EM4100 cards at a distance of 1 to 5 cm with a response time of less than 0.2 seconds. Easy system integration: WG26 format support plus RS232 TTL level serial output simplifies connection to access control panels, microcontrollers, and serial devices. Low power consumption: operates from 4.2 V to 5 V and draws under 40 mA, suitable for batterybacked or lowpower systems. Durable operation across common environments: designed for normal indoor operation and shortterm storage across typical temperature ranges. What it does and how it helps Reads 125 kHz ID EM4100 proximity cards and outputs the card data for downstream systems. This makes it suitable for access control, time attendance, inventory tagging, and other identification tasks where quick, reliable card reads are required. Provides data in WG26 format and via RS232 TTL level serial transmission for straightforward connectivity to existing controllers and serial interfaces, reducing integration time and development effort. Low current draw and small form factor reduce power and space requirements in embedded applications. Key specifications Model: WG26 output Supported card type: ID EM4100 Card frequency: 125 kHz Card reading distance: 1 to 5 cm Card read time: less than 0.2 seconds Output interface: RS232 TTL level output Example output: for ID card number 8644713 the RS232TX outputs the hexadecimal ASCII bytes 02 38 33 45 38 36 39 0D 0A 03 Power requirements: 4.2 V to 5 V, current below 40 mA Environmental temperature: working 0 C to 45 C, storage 20 C to 55 C Package: 2 pieces per lot Typical applications Access control: integrate with door controllers and WG26compatible access panels to read employee or visitor cards and grant or deny access. Attendance tracking: connect to microcontroller or serial terminals to record checkin and checkout events with minimal setup. Embedded projects and prototypes: use the RS232 TTL serial output to link the reader to development boards, custom control systems, or pointof devices for identification tasks. Practical notes Ensure the host device accepts RS232 TTL level signals or use an appropriate level shifter as required. Position the reader and cards to maintain the 1 to 5 cm reading range for reliable detection. The module is supplied in lots of two pieces.
