PCB D-SUB DE9 DB25 Connector

Product Overview

SUYI’s DE9 D-SUB Connector and DB25 D-SUB Connector cables are engineered exclusively for Computer PCB applications, delivering reliable data transmission and seamless integration into electronic systems. Available in two types—assembly-type D-SUB connector and injection-molded D-SUB connector—and two housing materials (PVC D-SUB Connector and metal D-SUB Connector), our cables address key customer concerns: signal interference, material durability, and compatibility with diverse PCB layouts. Whether for industrial control PCBs, desktop computer peripherals, or test equipment, our 9Pin D-sub Connector Cable and 25Pin D-sub Connector Cable meet UL, RoHS, and CE standards, making them a trusted choice for PCB manufacturers and electronics businesses worldwide.

Key Features

Dual Connector Types for Versatility: Choose between assembly-type D-SUB connector (easy maintenance, ideal for small-batch PCB production) or injection-molded D-SUB connector (waterproof, suitable for industrial environments).

Two Material Options: PVC D-SUB Connector (lightweight, cost-effective for general PCBs) or metal D-SUB Connector (anti-interference, corrosion-resistant, perfect for industrial automation).

High Signal Integrity: Tin-plated or gold-plated copper contacts ensure low resistance (≤0.01Ω) and stable data transmission, supporting speeds up to 100Mbps for Computer PCB data links.

Precise Pin Alignment: Machine-calibrated pins (tolerance ±0.1mm) ensure a tight fit with PCB sockets, preventing loose connections and signal loss.

Wide Compatibility: Works with 9Pin (DE9) and 25Pin (DB25) devices, including computer serial ports, industrial control modules, and test & measurement instruments.

Abrasion-Resistant Cable: The outer jacket uses PVC or TPE material that resists oil, chemicals, and bending (10,000+ bend cycles without damage).

UL-Certified Safety: All components meet UL 94 V-0 flame-retardant standards, ensuring safety in high-temperature PCB enclosures.

Specifications & Technical Details

Product Application Scenarios

Computer PCB Manufacturing: Used for connecting PCBs to motherboards, peripherals (e.g., serial ports), or test points in factory production lines.

Industrial Automation Systems: Metal D-SUB Connector cables are ideal for industrial PCBs in factories, as they resist electromagnetic interference (EMI) from machinery.

Data Transmission Equipment: Suitable for data modems, routers, and servers, where the DB25 D-SUB Connector ensures stable long-distance data transfer.

Desktop Computer Peripherals: DE9 D-SUB Connector cables connect legacy peripherals (e.g., old printers, scanners) to desktop PC motherboards.

Test & Measurement Instruments: Used in lab equipment (e.g., oscilloscopes, multimeters) to link test probes to Computer PCBs for accurate data collection.

Medical Equipment PCB Connections: UL-certified cables meet medical safety standards, making them suitable for PCB connections in diagnostic devices (e.g., blood pressure monitors).

Customization Service Process

Define Customization Needs: Specify requirements (pin count: 9Pin/25Pin; connector type: assembly/injection-molded; material: PVC/metal; length: 0.3m–10m) via our inquiry form.

Material & Design Confirmation: Our team provides a material sample (PVC/metal) and 2D design drawing for your approval; confirm details like contact plating (tin/gold) and cable color.

Prototype Production & Testing: Produce 1–5 sample cables, test for signal integrity (no interference) and fit (compatible with your PCB), and send samples for your verification.

Mass Production & Inspection: Start bulk production with batch inspections (10% random sampling for signal and durability tests); provide a quality report with each order.

Delivery & Technical Consultation: Ship via UPS/TNT (2–5 days for North America/Europe); include a technical datasheet and offer post-delivery support for PCB integration issues.

Quality Assurance & After-Sales Support

Rigorous Material Testing: All materials (PVC, metal, copper) undergo certification checks (UL, RoHS) to ensure compliance with global standards.

Signal Performance Validation: Each cable is tested for signal loss (≤1%) and EMI resistance (metal connectors only) using specialized equipment.

6-Month Warranty: Free replacement for cables with manufacturing defects (e.g., loose pins, insulation damage); discounted repairs for user-caused issues.

Professional Technical Advisory: Our engineers offer guidance on material selection (e.g., PVC vs. metal for industrial PCBs) and PCB compatibility checks.

Fast Replacement Service: Defective cables are replaced within 3 working days of confirmation, with free return shipping for global customers.

FAQ

Which material (PVC or Metal) is better for industrial Computer PCB applications?

A: Metal D-SUB Connector cables are recommended for industrial use—they shield against EMI from factory machinery and withstand harsh conditions (dust, temperature changes). PVC D-SUB Connectors work well for indoor, low-interference PCBs (e.g., desktop peripherals).

Is the DE9 cable compatible with all 9Pin computer peripherals?

A: It works with most standard 9Pin peripherals (e.g., RS-232 serial printers, modems). For non-standard devices, share your peripheral model, and we’ll confirm compatibility or offer a customized D-sub Connector Cable.

How long does gold-plated DB25 cable customization take?

A: Prototypes take 3–5 working days, and mass production (500+ units) takes 7–12 working days. Gold plating adds 1–2 days to production time compared to tin plating.

Do you offer UL-certified cables for medical Computer PCBs?

A: Yes! Our UL-certified DE9/DB25 D-SUB Connector Cables meet medical safety standards (ISO 13485) and are commonly used in medical PCB connections (e.g., patient monitors).
