Heilind Electronics, a leading global distributor of interconnect, electromechanical, and sensor solutions, is pleased to announce that it now stocks the 3M™ Four-Wall Header 2500 Series, a versatile 100″ × .100″ wire-to-board connector designed to deliver space-saving performance, reliable mating, and wide design flexibility in industrial, medical, test, and instrumentation applications.
Product Highlights
Heilind now carries the complete series of 3M™ Four-Wall Header 2500 Series products, including straight through-hole, right-angle, surface mount, multiple positions (6-, 10-, 14-, 24-, 36-, up to 50-pos), and options for dual or center-slot polarization, exposed solder tails, gold plating (10 µ″ or 30 µ″), and optional retainer clips for vibration resistance.
Features & Benefits
-
Low-profile, space-saving design: The compact .100″ × .100″ header maximizes PCB real estate, allowing more functionality in less space.
-
Center-slot and dual-slot polarization: These polarization options help prevent mis-insertion, speed assembly, and ensure compatibility with competitive mating connectors in the field.
-
High-temperature insulator for lead-free soldering: A high-temp plastic insulator tolerates modern no-lead solder processes and IR reflow environments, supporting both through-hole and “paste-in-hole” techniques.
-
Versatile mounting options: Available in right-angle versions with exposed solder tails for easier cleaning and lower repair costs, and straight surface-mount versions for non-through-hole assembly.
-
Optional retainer clip: An optional clip secures mating components in high-vibration environments for enhanced reliability.
-
Gold-plated contact options: Contacts are offered in 10 µ″ or 30 µ″ gold plating to improve corrosion resistance and long-term connection performance.
Applications & Use
The 3M 2500 Series is ideally suited for a broad range of applications:
-
Industrial control systems and factory automation – space-efficient and vibration-resistant headers provide rugged operation on PCBs embedded in machinery.
-
Test, measurement and laboratory equipment – accurate polarization and durability support precision connectors and interchangeability.
-
Medical electronics – compact layout, lead-free solder compatibility, and high reliability meet demanding medical standards.
-
Instrumentation – secure mating under shock and motion, plus multi-position flexibility, supports modular instrument design.
Heilind’s customers in these sectors can now source the 3M Four-Wall Header 2500 Series directly, with immediate availability through Heilind’s stocking package arrangement. Design engineers and procurement teams can tap into Heilind’s extensive inventory and technical expertise to quickly specify, sample, and integrate these connectors into new and existing designs.
