Our Breakaway Snap-Off Single Row Male Pin Header Strip Connector 2.54mm Pitch 40-Pin Customizable Length 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.

Key Features
  • User-Configurable Pin Count: Pre-scored insulator body enables clean breakaway into any desired pin count from 1 to 40 positions using simple hand tools or automated cutting fixtures
  • Clean Break Surface: V-groove scoring between every position ensures consistent break quality with minimal insulator burr, maintaining connector aesthetics and dimensional accuracy
  • Dual-Purpose Design: Functions as both a standard pin header strip for PCB mounting and as an interconnect cable header when used with IDC ribbon cable connectors in wire-to-board applications
  • Cost-Effective Inventory: Single 40-pin strip SKU replaces multiple fixed-pin-count part numbers, reducing inventory carrying costs and simplifying procurement for low-to-medium volume production
  • Extended Temperature Range: PA6T insulator maintains mechanical integrity through repeated breakaway operations and sustained high-temperature environments up to 105°C
  • Production-Ready Quality: Each breakaway position maintains full electrical and mechanical specifications identical to fixed-pin-count versions, with no degradation in contact resistance or mating force

Applications

Breakaway pin header strips are the universal prototyping and low-volume production interconnect solution used extensively in electronics laboratories, university research facilities, maker spaces, and R&D departments worldwide. The snap-off capability enables rapid breadboarding and perfboard assembly where pin-count requirements vary between design iterations, making them an indispensable component in engineering prototype development. In production environments, breakaway strips enable flexible configuration of test points, programming headers, and configuration jumpers on industrial control boards, power supply modules, and embedded system development platforms. They are also commonly employed in educational robotics kits and STEM learning platforms where modular connectivity is essential.

Packaging & Quality Assurance

Standard packaging in anti-static PE bags of 100 strips, with optional rigid tube packaging for automated handling. Each strip is individually inspected for scoring consistency and pin alignment before packaging. Bulk packaging options include 500-strip boxes with desiccant for extended storage. We provide cutting fixtures and breakaway tools for clean, repeatable pin-count separation in production environments, available as complementary accessories with volume orders.

Our manufacturing facility operates under ISO 9001:2015 certified quality management system with comprehensive traceability from raw material receiving through finished product shipment. Each production lot undergoes statistical process control monitoring, and certificate of conformance documentation is available upon request. We maintain substantial inventory of standard configurations to support just-in-time delivery requirements while offering flexible customization for specialized pin lengths, plating options, and packaging formats. Engineering samples are available within 48 hours for qualification testing, and our technical team provides application engineering support to assist with connector selection and PCB layout optimization. With over a decade of connector manufacturing expertise, we are committed to delivering interconnect solutions that exceed performance expectations while maintaining competitive pricing for volume production programs.
