125KHz User Manual
1. Overview
KR6**E Series 125KHz is a non-contact RF ID card reader that is developed based on the ISO/EM4001
international standard protocol. It adopts the high-performance RF card reader circuit designed by ZKTeco.
It is characterized by the high integration degree, strong anti-interference capability, compact size, stable
performance, and cost effectiveness. KR6**E Series provides the Wiegand 485 communication interface,
and is applicable to various RF identification fields, such as the access control, attendance, charging,
anti-theft, and patrol systems.
2. Features
The card reader is equipped with a card-reading antenna that works at 125KHz.
The effective distance ranges from 0 to 10cm, depending on the working environment and card type.
The data receiving time is less than 80ms within the effective distance.
The card reader adopts the single +12 VDC power supply, and the operating current is less than
80mA.
The card reader is produced using the fully closed rubber injecting operation to achieve the
waterproof and moisture-proof effects. The card has a keypad, and supports password identification.
The effective distance is associated with the voltage of the power supply, used ID cards, and operating
environment.

6. Precautions
1. The operating frequency of the card reader is 125KHz. Therefore, interference frequency ranging from
100KHz to 150KHz cannot exist on the site where the card reader is installed.
2. To prevent emission magnetic fields of card readers from affecting each other, the installation distance
between every two card readers must be greater than 10 cm.
