The UM 45-D37SUB/B/FRONT/Q interface module from Phoenix Contact is a compact, slim-line module for mounting in standard rail slots (NS 35/7,5) and serves as an interface for industrial bus systems. It features a D-Subminiature socket strip with 37 pins and is designed for mounting perpendicular to the rail direction. Connection is made via screw terminals, ensuring a secure and reliable electrical connection. The module is part of the VARIOFACE series, developed for modular and flexible installations in automation technology.

Applications
This module is used in industrial automation technology where a reliable and compact interface for data and control lines is required. It is suitable for applications requiring a D-Sub connection with 37 contacts, such as in control systems, fieldbus systems, or when connecting sensors and actuators. Mounting perpendicular to the NS 35/7,5 rail enables optimal space utilization in enclosures and control units.

Functions and Equipment in Detail
The module provides a D-Subminiature socket strip with 37 contacts, secured via screw terminals. This design ensures a mechanically stable and electrically secure connection, even under industrial conditions involving vibrations and mechanical stress. The slim-line form allows dense mounting in enclosures, minimizing space requirements. Mounting perpendicular to the rail direction enables flexible arrangement in enclosure planning.

Technology Explained Simply
The D-Subminiature socket strip is a standard connector in industry, used for serial data transmission and control tasks. The 37-pin configuration provides sufficient contacts for complex applications. The screw terminals ensure that wire connections are not loosened by vibrations or mechanical stress. The slim-line form of the module reduces space requirements in enclosures and allows denser mounting of components.

Compatibility and Accessories
The module is compatible with pre-wired cables of types CABLE-D-37SUB/M/OE/0,25/S in various lengths (1.0 m to 6.0 m) as well as cables of types CABLE-D37SUB/B/S/KONFEK/S in lengths from 50 to 600 cm. These cables are specifically designed for connection to D-Sub socket strips and enable flexible and reliable wiring. The cables are equipped with a D-Sub plug that can be directly inserted into the module’s socket strip.

Mounting and Installation
Mounting is done perpendicular to the NS 35/7,5 rail, inserting the module into the corresponding rail slot and securing it. The screw terminals allow for a secure connection of the wires. The slim-line form requires no additional mounting aids, and installation can be done without tools, provided the rail is already prepared. Wiring is done via the D-Sub socket strip, connecting cables with matching plugs.

Operational Advantages
The module provides a compact and robust interface for industrial applications. The screw terminals ensure a reliable electrical connection, even under demanding operating conditions. The slim-line form reduces space requirements in enclosures, simplifying planning and maintenance. Compatibility with standardized cables enables flexible and quick installation.
