Key Specifications
The RM125SA/SF is a proximity card reading module for transmitting radio frequency 125KHz ASK/FSK system. It is easily to be used to design the RFID products. Reading distant up to 70mm. the module operating voltage range is DC +3.0V to 5.5V. Output 21,26,39,41,44,48 bits data in Wiegand format or 85, 95,100, 115, 120 bits data in magnetic stripe ABA track II format which is most prevalent used in the industry, provide more feasibility to the users. A Bi-color LED enhances user feedback. The LED normal state is red when the proximity card ID is read and the ID code is transmitted to the host system, the LED turns green. The typical action time is 200ms.
