Siemens Industrial Ethernet RJ45 FastConnect -liitin 6GK1901-1BB30-0AE0

Gigabit-ready and field-proven, the Siemens 6GK1901-1BB30-0AE0 delivers a robust RJ45 connection for PROFINET and Industrial Ethernet networks. Its FastConnect insulation displacement technology strips and terminates all 8 wires in a single motion, cutting installation time by up to 80% compared to traditional crimping.

Overview

This industrial-grade RJ45 plug is engineered for 10/100/1000 Mbit/s data rates over Siemens IE FC TP cables (4x2, AWG24). The straight 180° cable outlet suits tight cabinet layouts and machine-level wiring. A full metal housing with integrated shielding provides excellent EMC protection, while the IP20 rating matches typical control panel environments.
