D-sub 25-pin connector ShiverPeaks 79125-1, 25 contacts, female

D-sub 25-pin connector ShiverPeaks 79125-1 is a 25-contact female connector designed for reliable signal and data connections in serial and parallel cabling. The connector follows the standard D-sub form factor and pinout for 25-contact interfaces, and it is intended for cable assemblies, panel mounts, and equipment where a compact, mechanically secure 25-pin connection is required. The female contact arrangement provides mating compatibility with standard male DB-25 plugs and supports a range of low-voltage digital and analog signals commonly used in industrial and computer peripheral applications.

Advantages

The connector offers a compact D-sub housing with a secure fastening method to maintain stable mechanical and electrical contacts under typical operational conditions. Standard 25-contact layout ensures compatibility with existing DB-25 cabling and equipment. The female contact design reduces risk of bent pins during mating and is suitable for repeated plug cycles found in maintenance and test environments.

Suitable for

• Serial communication ports and RS-232/RS-422 cabling
• Parallel interfaces and equipment requiring multiple signal lines
• Industrial controllers, instrumentation, and measurement devices
• Cable assemblies, panel mount adapters, and repair of legacy systems

Key specifications

• Connector type: D-sub 25-pin, female
• Contact count: 25
• Mounting style: cable / solder termination suitable for cable assembly
• Contact material and plating: standard conductive contacts suitable for signal transmission (factory plating unspecified)
• Mechanical fastening: integrated fastening points for screws or thumbscrews to secure mating connector
• Application environment: suitable for low-voltage digital and analog signal connections in industrial and computer peripheral contexts

How to use

Prepare the cable by stripping the outer jacket and arranging individual conductors according to the required pinout. Solder each conductor to the appropriate female contact or use the specified solder termination points following the connector's assembly instructions. Verify correct wiring against the target pinout before final assembly. After wiring and insulation, mate the connector with a compatible male DB-25 plug and secure using the mechanical fasteners to ensure stable contact and strain relief. Perform a continuity test to confirm correct connections and check for shorts before placing the assembly into service.

Recommendations

Use the connector with appropriate strain relief and cable shielding in environments with electrical noise. Avoid exposing soldered joints to excessive mechanical stress and follow recommended torque for fastening screws. For reliable long-term operation, inspect contacts periodically and replace the connector if signs of corrosion or wear appear.
