Machined Pin vs Stamped Pin: Quick Comparison

Frequently Asked Questions

Q1: What is the main difference between your Machined Pin and Stamped Pin D-Sub connectors?

A: The primary difference lies in reliability, current-carrying capacity, and durability:

• Machined Pins are CNC-turned from solid copper bars, offering a solid structure, high mating cycles ($\ge 1,000$), higher current rating (5A), and excellent vibration resistance. They pass a 48-hour salt spray test, making them ideal for aerospace, railway (EMU), and industrial automation.

• Stamped Pins are formed from thin copper strips, supporting up to 3A with fewer mating cycles ($<500$). They are more cost-effective for consumer electronics or applications with infrequent plugging.

Q2: Can the 5A current rating be applied to all pins simultaneously?

A: The 5A current rating is per individual pin. However, in full-load scenarios or enclosed environments, temperature rise should be considered. Our connectors use UL94V-0 rated PBT glass-filled insulation to maintain high resistance ($3000\text{M }\Omega\text{ min @ 500V}$) even under high-current operations. If your application requires high-current continuous loading on all pins, please contact our engineering team to review thermal limits.

Q3: How do these connectors perform in high-vibration environments like high-speed trains (EMU)? A: Our Machined Solid Pin version is specifically designed for high-vibration environments. The CNC precision-machined pins ensure extremely tight mechanical tolerances and consistent, continuous contact pressure. Unlike stamped hollow pins, they are not prone to material fatigue or intermittent signal drops under continuous shock or vibration.

Q4: What mounting and locking options do you offer for PCB layout?

A: We offer flexible configurations to fit various PCB designs:

Orientation: Straight DIP type (Vertical) and 90-degree Right-Angle configurations.

Locking Mechanism: Board-mount options include Screw-Lock (for secure cable retention in high-vibration environments) and Rivet options (for fast assembly). Please refer to our technical drawings for the exact P.C.B layout, hole diameters, and pitch dimensions.

Q5: Are your shell sizes compliant with industry standards? (e.g., DE-9 vs. DB-9)

A: Yes, our connectors follow standard industry naming and sizing. While commonly referred to as DB9, DB15, DB25, and DB37 in the market, they correspond to standard shell sizes: DE-9, DA-15, DB-25, and DC-37. They are fully interchangeable with standard D-Sub footprints.

Q6: What plating options do you provide for the contacts?

A: Our standard product features Gold Flash on the contact area over pure copper contacts, providing minimal signal loss and an excellent balance between cost and oxidation resistance. For specific high-reliability requirements (e.g., thicker gold plating like $3\mu”$, $15\mu”$, or $30\mu”$), please contact us for custom options.

Q7: What is the flammability rating of the insulator material?

A: The insulator is made of PBT glass-filled material with a UL94V-0 flame retardant rating, which is the highest safety rating for plastic components, ensuring self-extinguishing properties in case of fire.

Q8: Can we request custom pin counts, modified tail lengths, or specific plating thicknesses? A: Yes. We provide full customization services, including custom P.C.B tail lengths, selective heavy gold plating, and specialized hardware pre-assembly. Please send your detailed specifications or 2D/3D drawings to our sales director at nick.xu@lyd123.com for a technical review and quote.

Q9: Do you provide free samples for engineering evaluation? A: Yes, we can provide prototype samples for qualifying OEM/ODM projects and engineering evaluations. Please contact us via email with your project details and the specific part number you need.
