Highlighted by "flexible customization for scenario adaptation and precise fulfillment of design requirements," this series not only supports on-demand adjustment of plastic height according to specific installation spaces but also offers two mainstream mounting methods—DIP (Through-Hole) and SMT (Surface Mount)—along with single-row and double-row connection options. It fully covers the interconnection needs of various fields such as consumer electronics, medical equipment, industrial control, and smart home. Special high-temperature resistant materials enhance product durability, and customized plating specifications together lay the foundation for the series' performance advantages in the industry.

Core Customization Advantages: Breaking the Limitations of Design Space

In the highly competitive connector market, the most prominent competitiveness of JVT's pin header and socket strip series lies in the flexibility of "on-demand customization and rapid response." This customization capability is not a simple specification adjustment but aligns with user needs from the source of design. Especially for the common problem of limited design space in various electronic devices, it forms a unique solution value:

• Precise Adjustment of      Plastic Height: Relying on JVT's mature flexible stacking technology, the      plastic insulator of the connector can be precisely adjusted up and down      along the terminal pin with minimal increments. The height range extends      from the standard height for conventional applications to the extra-high      specification required for special scenarios. Whether it is the      millimeter-level compact space inside ultra-thin wearable devices or the      vertical connection needs of multi-layer circuit boards in industrial      control cabinets, seamless adaptation can be achieved through this precise      customization. More advantageously, there is no minimum order quantity      required for customized products of this series, and no additional mold      opening costs are incurred. With JVT's customized production and logistics      network, it can support rapid delivery within 1 day, greatly shortening      the customer's R&D and production cycles.
• Diverse Combinations of      Mounting and Connection Methods: Targeting the design processes of      different PCB boards, the complexity of circuit layout, and the operating      environment of equipment, the series offers dual mounting options—DIP      through-hole type, with its robust pin structure penetrating the PCB      board, is suitable for scenarios requiring high mechanical strength such      as industrial equipment and medical instruments. The stable connection      formed after soldering can effectively resist external influences such as      vibration and impact, achieving excellent anti-vibration performance in      the industry; SMT surface mount type adopts a low-profile structure      design, with the mounting height of some models only 4.3mm, which can      perfectly adapt to surface mount technology. Cooperating with automatic      placement machines, it realizes efficient mass production, significantly      improving the assembly efficiency and product yield of the production      line. In terms of connection methods, the single-row design can simplify      the connection process of conventional circuits and reduce wiring      difficulty; the double-row structure can double the number of I/O interfaces      within the same PCB footprint, supporting high-density arrangement of up      to 100 I/Os, easily meeting the integrated needs of signal transmission      and power supply in complex circuits.
• Reliability and      Compliance Assurance: Strict control is exercised in material selection      and process control of the products. The entire series uses      high-elasticity and high-conductivity phosphor bronze as the terminal base      material, with tin-nickel barrier layer or gold plating on the surface.      This not only ensures excellent electrical conductivity but also greatly      improves the resistance to electrochemical corrosion, extending the      product service life. Some high-end models have also passed 2500 high-life      cycle tests. At the same time, the entire series of products comply with      ISO-9001 quality management system standards and environmental directives      such as RoHS and REACH. Special models developed for medical scenarios      also have non-magnetic characteristics, which can avoid interfering with      the magnetic field environment of medical imaging equipment.

Pitch Segmentation: Scenario-Based Adaptation Logic of Three Specifications

The design of three different pitch specifications—1.27mm, 2.00mm, and 2.54mm—is not a simple size difference. Based on in-depth research on application scenarios in various industries, JVT has targeted three core solutions: "high-density miniaturization," "balanced adaptation," and "universal standardization." It forms a clear product positioning gradient covering low, medium, and high demand levels, allowing customers to quickly match the optimal solution according to their actual needs:

1.27mm Pitch: Core Choice for High-Density Miniaturization

As a representative specification in the field of fine-pitch connectors, the 1.27mm pitch products have core advantages of "ultra-compact layout + high-speed stable transmission." Their pins adopt precision stamping and arrangement processes to maximize signal transmission density within limited PCB space while ensuring excellent electrical performance. They are widely suitable for scenarios with high requirements for space and transmission rate:

• Miniaturized Consumer      Electronic Devices: Such as the connection between the charging case and      the earphone body of TWS wireless earphones, the interface between the      sensor module and the main control chip of smart watches, the circuit      connection of the eye-tracking module of VR glasses, and the signal      interconnection between the internal main board and sub-board of smart      game consoles, as well as camera modules. It can support high-speed data      transmission, perfectly meeting the transmission needs of high-definition      audio, real-time images and other data. At the same time, the low-profile      structure of its SMT version can effectively compress the internal space      of the device, helping to achieve the ultra-thin design goal of the      product.
• Precision Medical      Equipment: In the end effector control module of surgical robots, the      signal transmission link of 3D medical imaging equipment, and the      detection module of portable diagnostic instruments, this specification      connector ensures zero-delay and distortion-free transmission of      diagnostic data and control commands with its high reliability (passing      rigorous environmental test SET including high and low temperature cycles,      humidity alternation, salt spray test) and accurate analog signal      transmission capability. Its exclusive non-magnetic design can perfectly      adapt to the strong magnetic field working environment of medical imaging      equipment such as MRI, avoiding interference with image quality.
• High-Density Industrial      Control Modules: Suitable for I/O expansion boards of PLC controllers,      signal acquisition modules of industrial IoT sensors, and data acquisition      terminals in intelligent manufacturing production lines. The double-row      1.27mm specification product can achieve double the number of signal      channels within the same PCB area as the single-row one. Combined with the      robust connection characteristics brought by the DIP through-hole mounting      method, it can withstand mechanical vibration, temperature fluctuation,      and electromagnetic interference common in industrial production sites,      ensuring the stable operation of industrial control systems.

2.00mm Pitch: Intermediate Solution Balancing Performance and Cost

As a "transitional" product connecting the 1.27mm fine pitch and 2.54mm standard pitch, the 2.00mm pitch specification cleverly balances a certain signal density and operational convenience. Its single-pin current-carrying capacity can reach 3A, effectively controlling costs while meeting the performance needs of mid-range equipment. It has formed a significant cost-performance advantage in domestic industrial control boards, mid-range consumer electronics, and smart home equipment, mainly suitable for the following scenarios:

It is not      only convenient for module disassembly and replacement during later      equipment maintenance but also can ensure connection stability during      long-term use. Its double-row design can realize synchronous transmission      of power and signals, greatly simplifying the internal circuit layout of      the equipment and reducing the risk of wiring errors.
• Smart Home Control      Units: Including the interface between the main control board and      fingerprint recognition module of smart door locks, the circuit control      interface of thermostats, and the drive module of smart lighting systems.      The 2.00mm pitch can perfectly adapt to the medium-scale circuit layout      needs of such equipment, and its flexible plastic height customization      function enables it to be easily embedded into the narrow installation      spaces of door panels, walls, or equipment casings. At the same time, the      SMT version supports automated soldering processes, which can seamlessly      match the large-scale mass production needs of smart home products,      effectively improving production efficiency and reducing labor costs.
• Mixed Power and Signal      Transmission Scenarios: Developed based on power connector technology, the      2.00mm specification product can achieve a large current transmission      capacity of 3A per pin, perfectly suitable for scenarios such as battery      management modules of small drones, charging interfaces of portable      projectors, and combined power and data interfaces of handheld measuring      instruments. Through the flexible combination of single-row terminals for      power transmission and double-row terminals for combined signal and power      transmission, the number of device interfaces can be effectively reduced,      making the product appearance design more concise and reducing the failure      risk caused by multiple interfaces.
