Wire Connector D-Sub 3 Harting 09 69 311 5172 Green Metallic

The Harting 09 69 311 5172 is a D-Sub 3 male wire connector with solder-cup terminations and a rated current of 5 A. It has 15 signal contacts plus 2 additional special contacts, a green metallic finish and a lightweight construction (approximately 9.3 g). Materials include glass-fibre-filled polyester (thermoplastic resin), tin-plated steel and copper alloy contacts. The connector is RoHS compliant and intended for reliable low-current signal and control connections.

Advantages

This D-Sub 3 connector offers solder-cup termination for secure wire connections and a compact, lightweight design that eases handling and installation. The tin-plated steel shell provides mechanical durability while copper alloy contacts ensure consistent electrical performance. The inclusion of two special contacts expands wiring flexibility for mixed signal or auxiliary functions.

Suitable for

• Low-current signal and control wiring
• Industrial or instrumentation panels
• Embedded systems and communication interfaces
• Applications requiring mixed signal and auxiliary contacts

How to use

Prepare individual conductor ends by stripping the insulation to the recommended length for solder-cup terminations. Insert each conductor into the appropriate solder cup according to your wiring diagram, then apply solder to form a solid joint. Verify contact assignments before final assembly, and mount the connector into its mating housing or panel using the appropriate fasteners.

Recommendations

Use suitable solder and flux for copper alloy contacts and avoid excessive heat to prevent damage to the thermoplastic resin body. For reliable performance, confirm current requirements do not exceed the 5 A rating and ensure proper strain relief for connected cables.
