MITSUBISHI USB-SC09-FX | USB to RS-422 Programming Converter Cable (MD8) — 3M
The Mitsubishi USB-SC09-FX is a USB-to-RS422 converter cable dedicated to the Mitsubishi FX Series PLC. Unlike the USB-SC09 which has dual connectors, this model has only the MD8 round connector for FX series, making it a more compact and FX-specific solution.

- MD8 / Mini-DIN 8-Pin (Male) on PLC side — for FX series PLCs with MD8F round socket
