Siemens 6GK1901-0DB50-6AA0 IE FC M12 Plug PRO 4X2 X-Coded 8-Pin Gigabit Industrial Network Connector

The Siemens 6GK1901-0DB50-6AA0 IE FC M12 Plug PRO 4X2 is an 8-pin, X-coded M12 field-wireable connector for SCALANCE W and SCALANCE X gigabit interfaces. Its FastConnect insulation-displacement termination supports transfer rates up to 10 Gbit/s over Cat6A-structured cabling. A metal enclosure with IP65/67 protection and a –40 °C to +85 °C operating range make it suited to harsh industrial and railway environments.

Selection Notes

The X-coding on this connector distinguishes it from D-coded M12 variants (which top out at Fast Ethernet) and A-coded variants (100 Mbit/s industrial sensor I/O): only X-coded contacts carry the pin geometry required for Cat6A 10GBASE-T. Choosing the 6GK1901-0DB50-6AA0 over the standard IE FC M12 Plug PRO 2×2 (D-coded) is mandatory wherever SCALANCE W access points or switches expose a gigabit or 10-gigabit M12 port. The axial (180°) cable outlet suits panel penetrations and cabinet gland plates where inline routing is needed; installations requiring a 90° exit should use the right-angle variant instead. PoE+ pass-through (up to 30 W per IEEE 802.3at) is supported at the mated interface, so no separate power connector is needed for PoE-powered devices.

Applications

This connector targets SCALANCE W IWLAN access points with M12 gigabit ports installed in rolling stock, trackside cabinets, and outdoor machine enclosures where IP67 ingress protection is a panel-level requirement. The –40 °C lower operating limit and EN 50155 / EN 45545-5 approvals satisfy rolling-stock procurement specifications without additional derating. Silicon-free construction meets cleanliness requirements in automotive paint-shop and semiconductor environments.
