Product Introduction

D-SUB Connectors (PCB Mount & Solder Type DB Male & Female Connectors)

Overview

D-SUB connectors, commonly referred to as DB connectors, are classic industrial rectangular signal interfaces. This product range includes PCB through-hole mount type and solder-cup type, covering popular specifications DB9, DB25, DB37, available in male (pin) and female (socket) versions. Widely adopted for signal transmission in industrial controllers, testing instruments, serial communication equipment and automation machinery.

Structure

1. Metal Shell: Zinc alloy housing with mounting holes for secure installation. It provides EMI shielding to reduce electromagnetic interference and ensures stable connection under vibration.
2. Insulator: High-temperature resistant insulating base to separate contacts and avoid short circuits.
3. Gold-plated Contacts: Solid copper contacts plated with gold, featuring excellent conductivity, oxidation resistance and wear resistance to support frequent mating.
4. Two main mounting styles:

• PCB Mount: Straight pins for soldering directly onto printed circuit boards
• Solder Cup: Rear terminals for wire soldering to assemble custom cable harnesses

Key Features

✅ Industrial-grade stable connection Metal housing can be locked in place, effectively preventing loose contact in vibrating working environments. ✅ Superior signal performance Gold-plated contacts guarantee reliable transmission of serial signals, control signals and low-speed data. ✅ Multiple specifications & orientations Available in DB9, DB15, DB25, DB37, male/female, PCB mount and solder versions to meet diverse assembly demands. ✅ EMI shielding function Metal shell suppresses electromagnetic interference, ideal for precision industrial equipment.

Typical Applications

Industrial control devices, measuring & testing instruments, serial communication ports, automation equipment, medical instruments and signal harness assemblies.
