Waterproof 125KHz RFID Card Reader Wiegand 26 Access Control
Waterproof 125KHz RFID Card Reader Wiegand 26 Access Control
Waterproof 125KHz RFID Card Reader – Wiegand 26 | Access Control System
Upgrade your entry security setup with this reliable 125KHz RFID Card Reader featuring Wiegand 26 output. Designed for seamless integration into access control systems, this compact slave reader delivers fast, consistent card recognition with dual LED status indicators and an audible buzzer — all housed in a durable, waterproof ABS and resin enclosure built to withstand harsh environments.
⚠️ Important Note: This is a slave card reader — it does not store user data or manage cards independently. It must be paired with a compatible standalone access control board, attendance machine, or multi-door controller to function as a complete access system.

Installation Tips
- Always power off before installing or disconnecting the reader.
- Mount on wood, concrete, or brick surfaces. Avoid large metal surfaces within 10cm of the reader.
- Maintain at least 0.3 meters between two readers to prevent signal interference.
- Read range may vary based on card type and surrounding environment.
- The reader will not send data while the card remains stationary in the sensing field — a new swipe is required each time.

Frequently Asked Questions
Q: What type of cards does this 125KHz RFID reader support?
A: This reader supports standard 125KHz EM-format ID cards, including TK4001 and EM4100 card types. It does not support 13.56MHz smart cards (such as Mifare or HID iCLASS) in the standard configuration — custom orders for different frequencies are available with a minimum quantity of 30 units.
Q: Can this RFID card reader work as a standalone access controller?
A: No — this device is a slave reader only. It reads card data and outputs it via the Wiegand 26 (WG26) interface to a connected access control panel, standalone controller, or attendance machine. It cannot store card data, manage user permissions, or operate the door lock independently.
Q: Is this RFID reader suitable for outdoor installation?
A: Yes. The reader is built with a waterproof ABS and resin adhesive enclosure and operates across a wide temperature range of -25°C to +75°C, making it suitable for both indoor and outdoor access control installations in varying weather conditions.
Q: What output interface does this reader use?
A: The standard model outputs via Wiegand 26 (WG26), which is the most widely used access control communication protocol. Custom configurations supporting Wiegand 37, RS485, RS232, TTL, or HID format can be arranged for orders of 30 units or more — contact customer service for details.
