PLC MD8M–MD8M | Mini-DIN 8-Pin Male to Male Communication Extension Cable — 2M

The MD8M-MD8M is a generic serial communication cable with a Mini-DIN 8-Pin Male connector on both ends. It is used as an extension or pass-through cable between two devices that each have a round MD8 port — commonly for PLC-to-HMI or PLC-to-PLC communication links where the MD8 interface is shared.

2️⃣ Key Features

• Mini-DIN 8-Pin Male (MD8M) on both ends — pure extension cable, no signal conversion
• Pure copper conductor with aluminium foil shielding for signal integrity
• 2-metre cable — suitable for short panel-to-panel or device-to-device links
• Generic/universal — compatible with any device pairing that uses MD8 round connectors
