Siemens Industrial Ethernet FastConnect RJ45 plug, 145 2x 2 Part number 6GK1901-1BB30-0AA0

Product Overview

The Siemens 6GK1901-1BB30-0AA0 is the Siemens Industrial Ethernet FastConnect RJ45 Plug 145 2x2, a rugged RJ45 plug-in connector designed for Industrial Ethernet cabling using the FastConnect (FC) system. It enables reliable 10/100 Mbit/s network connections in industrial automation, with a sturdy metal housing and a 145° cable outlet — ideal for installations requiring compact, robust Ethernet terminations in control cabinets or field enclosures.

Key Features

• RJ45 plug-in connector for Industrial Ethernet (Cat5 / 10/100 Mbit/s)
• FastConnect (FC) system — enables quick and tool-less assembly with compatible IE-FC TP cables
• 4-wire TP FC cable connection (AWG 22) using integrated cut-and-clamp contacts — no separate crimping required
• 145° cable outlet — helps when routing cables in tight or shallow enclosures
• Rugged metal housing for industrial durability and mechanical protection
• Compact dimensions and light weight — good for tight spaces and panel mounting
• IP20 rating (when installed) suitable for standard industrial control cabinets
• Wide ambient temperature range — suitable for harsh industrial environments
• Re-usable up to 10 times — supports maintenance or reconfiguration without damage
