Sub-D-sovitin ShiverPeaks 78420, 9-napainen (DE-9) 25-napaiseen (D-Sub 25) sovitin

ShiverPeaks 78420 is a compact Sub-D gender changer that converts a 9-pin (DE-9) connector to a 25-pin D‑Sub 25 connector. Designed for serial and legacy D‑Sub interfaces, this adapter enables physical connection between equipment with different Sub-D pin counts without changing the cabling or ports on connected devices. The adapter is made of plastic housing with metal contacts to ensure basic mechanical alignment and signal continuity for standard non-powered serial links.

Advantages

The adapter provides a quick and reversible way to connect DE-9 and D‑Sub 25 connectors without soldering or rewiring. Its compact form factor and light-weight plastic construction make it easy to carry and fit in restricted spaces. The simple gender-changing function preserves pin mapping for common serial configurations and reduces the need for custom cables when integrating legacy devices.

Suitable for

• Connecting devices with 9-pin serial ports to equipment using 25-pin D‑Sub ports
• Field testing and bench diagnostics of legacy serial hardware
• Temporary or permanent interface adaptation in industrial and laboratory setups
• Integration of older peripherals with modern systems that retain D‑Sub connectors

Key specifications

• Connector conversion: DE-9 (female/male orientation as adapter) to D‑Sub 25
• Housing material: plastic
• Contact material: metal contacts designed for low-voltage signal transmission
• Form factor: compact, lightweight gender changer
• Intended use: passive mechanical adapter for signal routing (no power conversion)

How to use

Align the DE-9 side of the adapter with the device's 9-pin serial connector and gently insert until the mating faces are fully engaged. Attach the D‑Sub 25 side to the corresponding 25-pin connector of the other device, ensuring screws or thumbscrews (if present on the mating connectors) are secured to prevent accidental disconnection. The adapter requires no drivers or power; it functions as a passive mechanical interface. Verify pin mapping and signal compatibility for your specific equipment before applying communication protocols.

Recommendations

Use the adapter for signal-level serial connections only and avoid exposing it to moisture, excessive mechanical stress, or environments with strong electromagnetic interference. For applications requiring shielding, power conversion, or specific pin remapping, consider using purpose-built cables or active converters.
