Serial Extension Cable InLine DB37 Male/Male 5m

The InLine Serial Extension Cable InLine DB37 Male/Male 5m is a 5-meter beige extension cable designed to extend RS-232 style serial connections that use a 37-pin D-subminiature (DB37) connector. The cable provides a straightforward male-to-male connection for systems and devices that require a DB-37 interface, enabling flexible placement of equipment and easier cable routing in workstations, control cabinets, or test environments.

Advantages

This DB37 male/male extension cable offers a durable D-sub interface for reliable data transmission across the full 5 m length. Its standardized 37-pin connector ensures compatibility with equipment that uses DB37 ports. The neutral beige jacket integrates unobtrusively into many installations while providing adequate flexibility for routing. The cable design minimizes signal loss for short to medium distance serial connections and simplifies extending existing serial links without re-cabling equipment.

Suitable for

• Extending serial connections between devices with DB37 connectors
• Industrial control panels and PLCs that use 37-pin serial interfaces
• Laboratory and test equipment requiring temporarily increased cable length
• Workstation or rack installations where devices need repositioning without changing ports

Key specifications

• Connector type: DB37 male to DB37 male (37-pin D-sub)
• Cable length: 5 meters
• Cable color: beige
• Contact configuration: full 37-pin wiring suitable for parallel RS-232 or compatible serial signals
• Construction: shielded D-sub cable for stable signal transmission (standard D-sub cable construction)

How to use

Connect one DB37 male end of the extension cable to the DB37 female port on the device you wish to extend, and connect the other male end to the corresponding DB37 female port on the host or peripheral device. Tighten the connector thumbscrews or screws to secure the connection and prevent accidental disconnection. Route the cable to avoid sharp bends and areas with strong electromagnetic interference. Verify communication settings on connected devices as required for your serial protocol.

Usage recommendations

Use the cable for point-to-point serial extension within its 5 m length; if longer runs are required, consider serial repeaters or alternative cabling to maintain signal integrity. Avoid routing the cable parallel to high-voltage power lines and keep connectors free of dust and moisture for reliable long-term operation.
