125Khz RFID Long Distance Reader Module, 40CM, Serial

Description

• Reading distance is far
• Strong decoding capability
• Low power consumption
• Industrial grade, long continuous card reader performance is stable and reliable.
• Support standard access control standard – 26 bit Wiegand

Range:

• Built-in CPU decoding, direct serial port 9600 baud TTL level output card number, can also choose Wiegan 26 output card number, the use of very simple
• Comes with buzzer, indicator output pin. Direct read when power up.
• Module size 16 * 24MM, the volume is very small, the antenna can be any match (to support their own winding)
• The module uses a common 2.54mm pitch pin, can be easily embedded in various systems.
• Wide voltage supply 3.5V to 6V, current about 25mA
• Well tested, mature product

• Test the EM standard thick card (Support EM4100, 4001, TK4100, EM4305, etc. 125K RF card card serial number.).
  • Diameter 45mm coil can reach 25CM reader distance!
  • Use the 97mm coil to reach 40CM!
  • Support read through door/wall, etc
  • Card and key tag are available in store.Test result is 20cm thin card, and 14cm key tag.
• Notice demo video shows the best ideal setup, different setup can not get the same good result. 

Usage:

• To use with arduino, only need to connect module serial TX pin arduino serial RX pin, which is arduino D0 pin, also common ground.

Package includes

• main PCB board
• one filter capacitor
• 97mm size antenna
• and one test-proof card, which can make sure reach 40cm.
