Machine Pin Round Male Header Connector 2.54mm Pitch Precision Machined Contacts Dual Row PCB

Our Machine Pin Round Male Header Connector 2.54mm Pitch Precision Machined Contacts Dual Row PCB represents a precision-engineered interconnect solution designed for reliable board-to-board and wire-to-board connections in demanding electronic applications. Manufactured with high-temperature PA6T thermoplastic insulation and precision-stamped brass contacts, this connector series delivers consistent electrical performance across a wide range of operating conditions. Every connector undergoes rigorous quality inspection including contact resistance measurement, insulation resistance testing, and visual inspection under magnification to guarantee conformance to international standards.

The contact system utilizes high-conductivity brass alloy pins with selective gold or tin plating over nickel underplate, providing superior corrosion resistance and reliable mating cycles exceeding industry benchmarks. Our automated assembly lines employ precision insertion technology that ensures consistent pin alignment and coplanarity, critical factors for successful PCB mounting in high-volume production environments. The insulator body is molded from UL94V-0 rated PA6T material reinforced with 30% glass fiber, offering exceptional thermal stability up to 105°C continuous operating temperature while maintaining dimensional accuracy.

• Precision Machined Contacts: Solid brass pins turned on Swiss-type CNC screw machines deliver superior dimensional accuracy with round cross-section for reliable multi-point contact mating
• Enhanced Mating Durability: Smooth cylindrical contact surface eliminates sharp edges that cause insertion wear on female contacts, extending system-level connector life to over 1000 mating cycles
• Superior Contact Reliability: Multi-point gas-tight connection between round pin and tuning-fork or leaf-spring female contacts ensures consistent low resistance even under vibration and thermal cycling
• Medical & Aerospace Grade: Manufactured under stringent process controls with full material traceability, meeting cleanliness and reliability requirements for Class II and Class III medical devices
• Low Insertion Force: Polished contact surface finish reduces insertion force by up to 30% compared to square pin equivalents, facilitating easier manual assembly and reduced operator fatigue
• Extended Lifecycle Support: Mature manufacturing process with guaranteed availability of tooling, material, and production capacity for programs requiring 10+ year product lifecycle support

Machine pin round headers are the preferred interconnect choice for mission-critical applications where connector reliability directly impacts system safety and uptime, including patient monitoring equipment, surgical instrument interfaces, and diagnostic imaging systems in medical environments. In aerospace and defense applications, these connectors are specified for flight control computer backplanes, satellite telemetry modules, and ruggedized communication equipment where vibration tolerance and long-term reliability are paramount. The precision machined construction also makes them ideal for automatic test equipment interface panels, semiconductor wafer probe card interfaces, and precision laboratory instrumentation requiring low and stable contact resistance over thousands of connection cycles.
