Single Row Straight Male Pin Header Connector 2.54mm Pitch Through-Hole PCB Mount 40-Pin Strip

Our Single Row Straight Male Pin Header Connector 2.54mm Pitch Through-Hole PCB Mount 40-Pin Strip 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. The single configuration ensures optimal PCB space utilization while maintaining excellent signal integrity for industrial control systems, consumer electronics, automotive modules, and medical device applications. 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 for automated pick-and-place compatibility.

• Precision-Stamped Contacts: Brass alloy pins with 0.64mm square cross-section provide reliable electrical connection with 2.0A current rating per contact
• High-Temperature Insulator: PA6T UL94V-0 rated thermoplastic body reinforced with 30% glass fiber withstands reflow soldering temperatures
• Versatile Pin Count: Available from 2 to 40 positions in single row configuration, with custom pin counts available upon request
• Selective Plating Options: Gold flash over nickel or tin over nickel plating options to meet cost and performance requirements
• Breakaway Design: Scored insulator allows easy separation into smaller pin counts without damaging adjacent positions
• Automated Assembly Ready: Consistent pin alignment within ±0.1mm tolerance ensures compatibility with pick-and-place equipment

Single row straight pin headers are widely deployed in embedded systems development boards, Arduino and Raspberry Pi accessory shields, industrial PLC I/O modules, LED display driver boards, power supply modules, and consumer electronic devices requiring reliable board-to-board interconnection. The through-hole mounting style provides superior mechanical retention for applications subject to vibration or mechanical stress, making these connectors ideal for automotive ECU modules, HVAC control boards, and industrial automation equipment deployed in challenging environments. The 2.54mm standard pitch ensures compatibility with industry-standard prototyping breadboards and perfboards, facilitating rapid design iteration during product development cycles.

Standard packaging options include anti-static PE bags for small quantities, rigid plastic trays for automated assembly lines, and tape-and-reel for high-volume SMT-compatible versions. Each package is clearly labeled with part number, lot code, quantity, and date of manufacture for full traceability. Moisture barrier packaging is available for extended shelf-life requirements. All products are 100% electrically tested prior to shipment with AQL 0.65 sampling inspection per MIL-STD-1916 standards.
