RFID Card Reader ZKTECO ACCERKR612D 13.56 MHz, Wiegand 34/66 interface

ZKTECO ACCERKR612D is an RFID card reader that supports 125 kHz proximity and 13.56 MHz ISO14443A (Desfire) cards. The compact, wall-mountable unit integrates with access control systems via Wiegand 34 or 66 outputs and is suitable for both indoor and outdoor installations thanks to IP64 protection and a wide operating temperature range.

Advantages

The reader combines dual-frequency reading (125 kHz and 13.56 MHz) with Wiegand 34/66 output for easy integration into existing access control panels. Its robust housing allows mounting on metal door frames, with LED indicators for allowed/denied access. Low power consumption and a compact footprint (86 x 86 x 20 mm) simplify installation in offices, residential buildings and other facilities.

Suitable for

• Access control points for offices and commercial buildings
• Residential entry systems and gated communities
• Integration with access controllers and security panels supporting Wiegand 34/66
• Outdoor and indoor doors where IP64 protection is required

How to use

Mount the reader on a flat surface or metal door frame and connect power (6–14 V DC) and the Wiegand output to the access controller following the controller manufacturer’s wiring diagram. Present compatible 125 kHz proximity or 13.56 MHz ISO14443A cards or tags within the specified reading range; the LED will indicate allowed or denied access. Ensure wiring is secure and connections comply with local electrical standards before powering the device.

Usage recommendations

For reliable operation, install the reader away from strong electromagnetic sources and allow sufficient clearance from other readers or metal structures that may affect read range. Use certified Desfire or ISO14443A cards for best compatibility and periodically check seals and mounting hardware to maintain IP64 protection.
