Overview
The Chafon CF561 is an all-in-one UHF RFID access reader with a built-in 6 dBi circularly polarised antenna and a reading range of up to 6 metres. It reads standard ISO18000-6C (EPC Gen2) tags and connects directly to gate and barrier controllers through Wiegand, plus RS232 or USB for computers. With an IP65 weatherproof housing, it is ideal for vehicle access control, parking, weighbridges and asset identification.
