## Long description

The InLine serial extension cable DB37 male/male 3m provides a straightforward solution for extending existing DB37 serial connections.

Advantages
This DB37 extension cable offers reliable physical connection and straightforward plug-and-play use without requiring additional adapters or configuration. The 3-meter length balances reach and signal integrity for many short- to medium-distance serial links.

 Industrial control systems and PLCs where a DB37 extension is needed

Key specifications
 Connector type: 37-pin DB37 male to DB37 male
 Length: 3 meters
 Cable color: beige
 Contact configuration: full 37-pin wiring for serial/parallel signals
 Use environment: indoor (office, lab, industrial control panels)
How to use
Align each DB37 male connector with the corresponding female port and insert straight until the connector seats fully. If the connected devices provide thumbscrews or fastening points, secure the connectors to prevent accidental disconnection and to maintain stable signal contact. Avoid sharp bends or kinks near the connector ends; route the cable with gentle curves and keep it away from high-voltage power lines or sources of strong electromagnetic interference to preserve signal quality.
Usage recommendations
For reliable operation, verify pin assignments of the connected devices before use and confirm that both ends match required signal voltages and grounding. Store the cable coiled loosely when not in use and avoid prolonged exposure to direct sunlight or moisture. If used in electrically noisy environments, consider additional shielding or separation from power conductors to reduce interference.
