China 125kHz Yellow RFID Smart Keyfobs for Access Control

125kHz Yellow RFID Smart Keyfobs for Access Control
EM4200 is a CMOS integrated circuit intended for use in electronic Read only RF transponders. It is designed to replace directly the EM Microelectronic-Marin Read only ICs EM4100/4102 and EM4005/4105. Comparing to EM4100/4102 and EM4005/4105, the chip provides higher reading range performances and presents on its coil terminals bigger resonant capacitor (210pF and 250pF selectable by mask option).
This RFID Key fob is made of refined mold, advanced high temperature anti-corrosion material injection pressure, internal EM4200 chip package, by filling an epoxy resin, a combination of ultrasonic welding, can be waterproof, easy to carry features.
