The Telegärtner STX M12x1 KS D-kod. Cat.5 is a 4-pole, D-coded compact connector in category Cat.5, specifically designed for use in industrial networking applications. It serves as an interface for applications such as security and video surveillance (CCTV), passenger information systems (PIS), and production facilities with high-resolution cameras. The connector enables reliable data transmission in environments with high demands for mechanical robustness and environmental resistance, for example in rail vehicles or at airports for baggage inspection with X-ray equipment. The connection is made via an M12 circular connector, suitable for use in PROFINET environments and transmitting data rates up to 100 Mbit/s, in accordance with the Fast-Ethernet specification IEEE 802.3.

Applications
This connector is designed for industrial applications requiring high mechanical stability, protection against environmental influences, and reliable data transmission. It is particularly used in systems that require high data volumes, such as in rail vehicles, where cameras, switches, and other devices are networked. It is also suitable for production facilities for manufacturing monitoring or in security systems with CCTV cameras as part of the infrastructure. The D-coding according to IEC 61076-2-101 ensures unique assignment and prevents incorrect connections.

Functions and Features in Detail
The connector is supplied as a plug set and allows connection without special tools. It is field-terminable, enabling direct connection to different cable types at the installation site. The IDC technology (Insulation Displacement Connector) allows quick and secure connection of conductors without removing the cable insulation. The 360° shielding provides effective protection against electromagnetic interference, which is crucial for signal integrity in industrial environments. Multiple shielding contacts increase shielding reliability and prevent signal loss.

Technology Explained Simply
Category Cat.5 corresponds to standards ISO/IEC 11801 and DIN EN 50173-1 and guarantees data transmission up to 100 Mbit/s over a distance of up to 100 meters. D-coding is a mechanical coding that ensures only compatible plugs and sockets can be connected. Protection class IP67 means the connector is dust-tight and temporarily waterproof, making it suitable for outdoor use or in humid environments. Support for 4PPoE according to IEEE 802.3bt enables power supply over the network cable, eliminating the need for additional power supply lines.

Compatibility and Accessories
The connector is suitable for use in PROFINET environments and can be connected to devices supporting the relevant network and power supply standards. It is compatible with various cable types, allowing flexible adaptation to existing installations. The D-coding ensures compatibility with other D-coded M12 connectors.

Mounting and Installation
Installation requires no special tools, with IDC technology enabling quick and secure cable connection. The field-terminable design allows on-site adaptation, making installation flexible and efficient. The 360° shielding and multiple shielding contacts ensure a stable connection, even under challenging environmental conditions.

Operational Advantages
The connector offers high reliability through mechanical robustness, effective shielding, and protection against environmental influences. Support for 4PPoE reduces the number of required cables, simplifying installation and easing maintenance. D-coding prevents incorrect connections and increases system safety. The field-terminable design enables quick adaptation to existing cable structures, quickly restoring operational readiness.
