Product details

Huizhou Antenk Electronics Co., Ltd. (IATF16949, ISO9001, ISO14001 certified) presents the 2.54mm Pin Header Dual Row Double Plastic Straight Type. This male header features a 2.54mm pitch, dual row configuration, and a unique double plastic insulator design. Unlike standard single body headers, the double plastic construction consists of two separate molded blocks that encapsulate the pin rows independently. This design provides several advantages: improved mechanical retention on the PCB by distributing stress across two bodies, enhanced isolation between signal rows to reduce crosstalk, and greater resistance to pin deformation during mating. The insulator is molded from high temperature UL94 V-0 PBT or nylon 6/6, ensuring dimensional stability through wave soldering up to 260°C. Contacts are stamped from phosphor bronze with selective gold or tin plating on the mating area, and pure tin on the solder tails. Key specifications include current rating 3A per contact, contact resistance below 20 milliohms, insulation resistance above 1000 megohms, dielectric strength 500V AC, and operating temperature from -40 to +105 degrees Celsius. The straight vertical orientation allows direct PCB mounting and mating with dual row female headers. RoHS and REACH compliant, UL recognized under E472792.

Applications include industrial control boards, power supplies, automotive electronics, medical devices, and telecommunications equipment where high pin count reliability and signal integrity are critical. Usage method: solder the through hole tails to the PCB using wave or hand soldering. The double plastic design allows for staggered or independent soldering, and the two bodies can be used to separate analog and digital signals physically. Precautions: do not exceed 3A per contact, ensure PCB hole alignment for both plastic bodies, avoid excessive force during mating. Advantages over competitors: Antenks double plastic header offers superior resistance to pin bending under vibration compared to single body designs. The separated insulators prevent solder bridging between rows during wave soldering, reducing defects. Tighter coplanarity (within 0.05mm) ensures uniform solder joint height. Low MOQs of 1000 units with no tooling fees.

Production process: in house mold design for dual independent cavities, injection molding on 10 Japanese and Taiwanese machines, high speed stamping of pins on 9 presses, selective gold or tin plating, automated pin insertion into two separate insulators, assembly of both bodies onto a common carrier (or loose packing), 100 percent pin coplanarity and row alignment inspection, contact resistance and insulation tests, 48 hour salt spray test, and final QC with lot traceability. Free samples, 2D and 3D CAD drawings, and 24 hour technical support available. Contact Antenk for custom pin lengths, plating, and row spacing.
