Product Introduction

D-SUB Connector (Solder Type D-SUB Plug)

Overview

D-SUB connectors, also known as DB connectors, are widely used industrial rectangular interfaces. The items shown are solder-cup D-SUB connectors, including male (pin type) and female (socket type). Common specifications include DB9, DB15, DB25, DB37, DB50. From top to bottom in the picture: DB50 Female, DB37 Female, DB25 Female, DB15 Male.

Structure

1. Metal Shell: Zinc alloy housing with mounting holes and lock screw holes. It can be firmly fastened after assembly to prevent accidental disconnection and provides shielding against electromagnetic interference.
2. Insulator: High-temperature resistant white plastic base for isolating terminals and stable insulation performance.
3. Contact Terminals: Solid turned copper pins with gold plating. The gold plating offers anti-oxidation and wear resistance to ensure consistent electrical conductivity long-term.
4. Type: Solder-cup version. Wires can be directly soldered to the rear terminals for cable assembly, different from PCB through-hole types.

Key Features

✅ Industrial-grade reliable connection The metal housing enables screw locking, maintaining stable connection under vibration conditions, ideal for industrial controllers and instruments. ✅ Gold-plated solid contacts Turned solid copper contacts with gold plating deliver excellent conductivity and extended service life with repeated mating. ✅ EMI shielding performance Metallic shell helps reduce electromagnetic interference, suitable for transmission of control signals and serial communication data. ✅ Multiple specifications available Supports DB9 / DB15 / DB25 / DB37 / DB50, both male and female versions.

Typical Applications

Industrial control equipment, testing instruments, serial communication devices, automation machinery, medical equipment, and signal transmission harness assemblies.
