InLine serial extension cable molded DB37 male / female direct grey 3m

The InLine serial extension cable molded DB37 male / female direct grey 3m is a 3-meter shielded extension cable designed to extend DB37 serial connections between devices. The molded connectors provide stable mechanical and electrical contact, while the grey PVC jacket offers a neutral appearance and basic protection against abrasion. This cable supports straightforward point-to-point extension of 37-pin serial interfaces commonly used in industrial equipment, legacy systems, and specialized peripherals.

Advantages

The molded DB37 connectors ensure secure mating with consistent pin alignment and reduced risk of bent pins. A single-piece molding around the connector offers strain relief and reduces connector fatigue at the cable entry point. The 3 m length provides flexibility for equipment placement without intermediate adapters, and the neutral grey jacket blends with typical industrial and office environments. Construction emphasizes reliable signal continuity for serial communications.

Suitable for

• Extending DB37 serial connections between computers, controllers, and peripherals
• Connecting industrial equipment and automation controllers that use 37-pin serial interfaces
• Linking legacy hardware, test rigs, and diagnostic devices requiring a 37-pin extension

Key specifications

• Connector type: DB37 male to DB37 female, molded
• Cable length: 3 meters
• Color: grey jacket
• Cable jacket material: PVC
• Pin count: 37 contacts suitable for standard DB37 serial pinouts
• Design: direct extension (no active electronics)

How to use

Connect the DB37 male end of the extension cable to the female DB37 port of the source device and attach the DB37 female end to the target device's male connector. Ensure both devices are powered off when connecting or disconnecting to prevent accidental shorting. Secure screw locks on both connectors to maintain mechanical stability and prevent accidental disconnection during operation. Route the cable to avoid sharp bends and tight clamps that could damage the internal conductors.

Recommendations

For optimal performance, keep the cable away from high-voltage power lines and strong electromagnetic sources. Use the cable indoors or in protected environments; avoid prolonged exposure to direct sunlight or extreme temperatures. If longer runs or higher immunity to interference are required, consider shielded or grounded cable alternatives and verify device compatibility with extended cable lengths.
