Adattatore Sub-D ShiverPeaks 9 poli su 25 poli (modello 78421) adattatore per connettività seriale

The ShiverPeaks Sub-D adapter converts a 9-pin Sub-D (DB9) male connection to a 25-pin Sub-D (DB25) female interface. Model 78421 is a compact, plastic-bodied cable adapter intended to bridge devices with differing D-sub connectors so that serial and peripheral equipment can be connected without rewiring. It is suitable for serial communications, peripheral adapters, legacy computer ports and instrumentation where a simple, passive conversion between a 9-pin and 25-pin D-sub is required.

Advantages

This adapter provides a straightforward mechanical and electrical conversion between DB9 and DB25 connectors using a molded plastic housing that is lightweight and easy to handle. It preserves pin-to-pin continuity required for typical RS-232 serial connections and peripheral interconnections, allowing rapid adaptation of existing cables and equipment without soldering or custom cable assembly. The compact form factor and standard Sub-D connector dimensions ensure compatibility with common D-sub cable assemblies and panel connectors.

Suitable for

• Connecting RS-232 serial devices to equipment with DB25 ports
• Adapting computer peripherals and legacy terminals
• Laboratory instruments and test benches with mixed D‑sub interfaces
• Industrial control systems requiring straightforward connector conversion

Key specifications

• Input: 9-pin Sub-D (male)
• Output: 25-pin Sub-D (female)
• Housing material: plastic
• Connection type: passive pin-to-pin adapter for D-sub signals
• Form factor: compact inline adapter for cable-to-cable or cable-to-panel use

How to use

Insert the 9-pin Sub-D male plug of the cable or device into the adapter’s DB9 receptacle and secure the connector as required. Then connect a DB25 plug from the target cable or panel to the adapter’s DB25 socket. Ensure both connectors are seated fully and, if present, tighten any retaining screws to maintain mechanical stability. The adapter does not require power or configuration; it provides passive continuity between corresponding pins where wiring is compatible.

Recommendations

Use this adapter in systems where pin-to-pin mapping between DB9 and DB25 follows standard serial signal assignments. Verify the pinout of the connected devices to ensure compatibility before applying power or signals. Avoid exposing the adapter to excessive moisture, mechanical stress, or temperatures outside the operating range of connected cables and equipment.
