InLine serial extension cable 37 Pin DB37 male / male direct 3m

The InLine serial extension cable DB37 male/male 3m provides a straightforward solution for extending existing DB37 serial connections. With 37-pin male connectors on both ends and a 3-meter length, the cable maintains signal continuity for devices that use the DB37 interface. Its beige jacket offers a neutral appearance suitable for office, industrial and laboratory installations while ensuring functional, low-profile cabling.

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. The molded connector ends reduce strain on the contact area and the cable jacket provides mechanical protection appropriate for indoor installations.

Suitable for

• Extending serial connections between equipment with DB37 interfaces
• Laboratory instruments and test equipment requiring additional cable length
• Industrial control systems and PLCs where a DB37 extension is needed
• Office or server-room cabling for legacy parallel/serial devices using DB37

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.

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.
