RFID card reader ZKTECO PROID20 13.56 MHz, Wiegand 26 interface

ZKTECO PROID20 is a 13.56 MHz RFID card reader designed for access control systems. It reads ISO14443A contactless cards and transmits card data via the Wiegand 26 interface for integration with controllers and access panels. The reader features a compact, robust housing with LED indicators for access status and is suitable for installation on doors, gates or other secure entry points both indoors and outdoors.

Advantages

The PROID20 supports 13.56 MHz ISO14443A cards and provides fast read times (up to 300 ms). Its Wiegand 26 output ensures compatibility with common access controllers. The unit is IP65 rated for water resistance, operates in temperatures from -10°C to +65°C, and can be mounted on metal frames. Low current consumption and a durable ABS/PC enclosure make it practical for continuous access control use.
