Delock Serial Cable RS-232 D-Sub 9 Female to JST XH 4 Pin Female 25 cm

The Delock serial cable is a specialized connection solution designed to bridge the gap between standard RS-232 serial interfaces and internal electronic components. Featuring a D-Sub 9 female connector on one side and a 4-pin JST XH female connector on the other, this 25 cm cable provides a reliable link for data transmission in various technical applications. Its compact design and precise connector types make it an essential tool for integrating serial devices with custom circuit boards or internal hardware modules.

Advantages

This cable offers a high degree of compatibility for users needing to connect external serial equipment directly to internal PCB headers. The use of the JST XH connector ensures a secure and stable physical connection, which is critical for maintaining signal integrity in sensitive electronic environments. With a length of 25 cm, it provides sufficient reach for internal chassis wiring while minimizing cable clutter, ensuring a clean and organized setup for industrial or hobbyist projects.

Suitable for

• Connecting serial devices to custom PCB assemblies
• Industrial automation and control systems
• Prototyping electronic hardware
• Internal communication between serial interfaces and circuit boards

When it may not be suitable

This cable is not intended for long-distance data transmission due to its short length and specific connector interface. It is also not compatible with devices that require standard D-Sub to D-Sub connections or those using different pin pitch standards for internal headers.

Key specifications

• Connector 1: D-Sub 9 female
• Connector 2: JST XH 4-pin female
• Cable length: 25 cm
• Interface: RS-232

How to use

To use this cable, identify the RS-232 port on your external device and the corresponding 4-pin JST XH header on your internal circuit board. Carefully align the JST connector with the header pins, ensuring the orientation is correct to prevent damage. Connect the D-Sub 9 end to your serial device and secure it if necessary. Ensure that the pinout configuration of your specific hardware matches the cable wiring before powering on the equipment to avoid potential electrical issues.

What to consider before purchase

• Verify the pinout compatibility of your specific hardware
• Check the physical space available for the 25 cm cable length
• Confirm that your internal header is a JST XH type

Usage recommendations

Always ensure that the power is disconnected from your electronic devices before connecting or disconnecting the cable to prevent short circuits or damage to the interface components.
