The 6AV6671-3XY48-4AX0 is a 16-pole female connector for SIMATIC HMI key panels, with 3.5mm pitch and straight (180°) orientation. It uses spring-loaded terminals for tool-free wiring and accepts 0.14–1.5mm² conductors. The black PA66 GF30 housing is UL94-V0 flame-rated. Designed specifically for the KP8F PN and KP32F PN key panels.

Is this connector 16-pole or 12-pole?

It is 16-pole. Official Siemens documentation lists the 6AV6671-3XY48-4AX0 as a 16-pole connector. The 12-pole variant is the 6AV6671-3XY38-4AX0 — a different part number. The two connectors have different widths (28mm for 16-pole vs 21mm for 12-pole) and are not interchangeable. Verify your device pin count before ordering.

6AV6671-3XY48 vs 6AV6671-3XY38 — how do they differ?

Both are SIMATIC HMI female connectors with 3.5mm pitch, spring-loaded terminals, and black PA66 GF30 housing. The 3XY48 is 16-pole, 28mm wide, for KP8F PN and KP32F PN key panels. The 3XY38 is 12-pole, 21mm wide, for the KP8 PN key panel. Choose strictly based on your HMI device model — the pin count and physical width must match the panel PCB header.

Which HMI devices is this compatible with?

The 6AV6671-3XY48-4AX0 is the dedicated female connector for SIMATIC HMI KP8F PN and KP32F PN key panels. It plugs directly into the panel PCB header. Supplied in packs of 10 pieces without ejector. Always cross-reference your specific device documentation for the correct connector part number.
