Module RFID ELFON OPTIMA OP-MA765R-G graphite

The ELFON OPTIMA OP-MA765R-G is a high-performance dual-frequency RFID module designed for secure access control and identification systems. Featuring both low-frequency (125 kHz) and high-frequency (13.56 MHz) operation, it supports a wide range of card technologies including EM4100/EM4102, MIFARE Classic, MIFARE DESFire, and MIFARE Plus. The module offers selectable output interfaces (Wiegand 26/34-bit, RS232, RS485) and is housed in a durable ABS plastic enclosure with an IP65 rating, making it suitable for indoor and outdoor use. Its compact surface-mount design and integrated planar antenna ensure easy installation and reliable read ranges up to 8 cm.

Advantages

Dual-frequency support ensures compatibility with legacy and modern RFID cards. The multi-color LED and integrated buzzer provide clear visual and audio feedback for user interaction. With a wide input voltage range (9-16V DC) and low power consumption (max 80 mA), it is energy-efficient and versatile for various installations. Firmware upgradability allows for future enhancements.
