New Needle Seat Connector 1.27mm Lengthened Double Row Pin 2*25P All Copper Environmental Protection Gold-plated Manufacturer

Product Description

This 1.27mm Pitch 2×25P Extended Pin Header Connector is a compact male pin header designed for PCB-to-PCB and board-to-module interconnection where standard 2.54mm headers may occupy too much board space.

Featuring a 1.27mm pitch, 50 contacts in two rows, extended pin configuration, copper-based contacts and gold-plated contact surfaces, it is suitable for compact electronic assemblies requiring a high contact count within a limited PCB area.

Material & Construction

Copper Alloy Contacts

The connector uses copper alloy contacts, providing the conductive base required for PCB-to-PCB electrical interconnection. The mating area is specified with 0.25 μm gold plating, while the solder tail uses 1.27 μm matte tin plating.

Thermoplastic Insulator

The insulating housing uses thermoplastic material with a UL94 V-0 flammability rating, making the component suitable for PCB assemblies where material flammability requirements need to be considered.

Engineering Advantages

1. Compact Board-to-Board Interconnection

The 1.27mm pitch and 2-row, 10-position configuration provide a compact PCB-to-PCB interface for applications where board space is limited.

This makes the connector particularly relevant to:

• Compact control boards
• Embedded electronic modules
• Industrial control PCBs
• Communication equipment
• Computing modules
• Consumer electronics

2. SMT-Compatible PCB Assembly

The vertical surface-mount design is compatible with automated SMT assembly processes. The manufacturer specifies vapor-phase and IR reflow soldering as supported solder processes.

For high-volume PCB manufacturing, this can simplify integration into an existing surface-mount production process.

3. Defined Electrical Performance

The published specification provides measurable electrical parameters rather than relying only on general claims of reliability.

Key values include:

• 1A per contact current rating
• 125VAC voltage rating
• 20mΩ maximum initial contact resistance
• 50mΩ maximum contact resistance after test
• 1,000MΩ minimum insulation resistance

These figures provide engineers with concrete criteria for evaluating electrical suitability during connector selection.

4. Wide Operating Temperature Range

The specified operating temperature range is -55°C to +125°C, making this connector suitable for electronic equipment requiring a relatively broad operating-temperature envelope.

The actual suitability for a specific end product should still be evaluated against the complete system-level thermal and environmental requirements.

Step Custom Process

1. Requirement Collection → 2. Technical Evaluation & Quotation → 3. 3D Drawing Review & Confirmation → 4. Mold / Tooling & Prototype → 5. Sample Test (contact R, retention, reflow) & Approval → 6. Mass Production → 7. Final QC & Shipment.
