Non-contact radio frequency ID card reader
KR300 series products
1. overview
The KR300 series products are125KHz non-contact rf ID card reader, which is based on the
ISO/IEC14443A international standard protocol developed non-contact smart card serial number
card reader. It was designed by our company's self-designed high performance rfid circuit. It is
characterized by high level of integration, strong anti-jamming ability, small volume, stable
performance and high price performance. It provides the wegen 34 or wegen 26 communication
interface, which is suitable for all kinds of rfid applications such as door prohibiting, attendance,
charging, burglar, and patrol.
2. characteristic
2.1 The card reader comes with the card antenna, which is the same as PCBA. The
difference is the software version, the shell, the length of the wire
2.2 Different versions of software support different CARDS
2.3 Effective range from 0 to 5cm (depending on the work environment and different
CARDS)
2.4 The receiving time is less than 80ms within the valid distance
2.5 Single dc power + 12V power supply, operating current is less than 100mA
2.6 The IC section is Wiegand34bits and ID parts for Wiegand26bits standard format
data output
2.7 Fully enclosed adhesive, waterproof, moisture-proof
