As a manufacturer of domestic substitutes for imported connectors, JVT has been deeply involved in the connector market for decades. In response to the diverse design requirements of contemporary electronic devices towards miniaturization, high density and high reliability, it has precisely launched a series of pin and pin connectors with three core spacings of 1.27mm, 2.00mm and 2.54mm. This series takes "flexible customization to adapt to scenarios and accurately meet design demands" as the core highlight. It not only supports the adjustment of plastic height according to the specific installation space, but also provides two mainstream installation methods of DIP plug-ins and SMT patches. With single-row and double-row diversified connection options, it fully covers the interconnection needs of consumer electronics, medical equipment, industrial control, smart home and other fields. Special high-temperature resistant materials enhance product durability, as well as customized electroplating specifications, which together establish the performance advantage of this series of products in the industry.

Core customization advantage: breaking the limitations of design space

In the highly competitive connector market, the most outstanding competitiveness of the JVT pin header series lies in its flexibility of "on-demand customization and fast response". This customization ability is not a simple specification adjustment, but a design source to fit user requests, especially for the design space constraints that are common in various electronic devices, forming 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 in minimal increments along the terminal pin body. The height range extends from the ordinary height of conventional applications to the special heightening specifications required for special scenarios. Whether it is the compact millimeter-scale space inside the ultra-thin wearable device or the vertical connection requirements of the multi-layer circuit board in the industrial control cabinet, it can be seamlessly adapted through this precise customization. What's more advantageous is that this series of customized products does not require setting a minimum order quantity and does not incur additional mold opening costs. With JVT's customized production and logistics network, it can support fast delivery within 1 day, greatly shortening the customer's R & D and production cycle.

• Multiple combinations of installation and connection methods: According to the design process of different PCB boards, the complexity of circuit layout and equipment use environment, the series products provide dual installation options - DIP plug-in type with its solid pin structure running through the PCB board, suitable for industrial equipment, medical instruments and other scenes requiring high mechanical strength. The stable connection formed after welding can effectively resist the influence of external forces such as vibration and impact, and the anti-vibration performance reaches the excellent level of the industry; SMT patch type adopts a low-profile structure design. The installation height of some models is only 4.3mm, which can perfectly adapt to the surface mount process. With the automated placement machine, it can achieve efficient mass production, significantly improving the assembly efficiency and product yield of the production line. In terms of connection mode, the single-row design can simplify the connection process of conventional lines and reduce the difficulty of wiring; the double-row structure can double the number of I/O interfaces in the same PCB footprint, and can support up to 100 I/O high-density arrangements, easily meeting the integration requirements of signal transmission and power supply in complex circuits.

• Reliability and compliance guarantee: The products are strictly controlled in material selection and process control. The whole series uses high elasticity and high conductivity phosphor bronze as the terminal substrate, and the surface is matched with tin-nickel barrier layer or gold plating process, which not only ensures excellent electrical conductivity, but also greatly improves the ability to resist electrochemical corrosion and prolong the service life of the product. Some high-end models have passed 2500 high-life cycle tests. At the same time, the whole series of products comply with ISO-9001 quality management system standards and environmental directives such as RoHS and REACH. The 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 Subdivision: Three Specifications of Scenario Adaptation Logic

The specifications of 1.27mm, 2.00mm and 2.54mm are not simple size differences, but JVT's three core solutions of "high-density miniaturization", "balanced adaptation" and "universal standardization" based on in-depth research on application scenarios in various industries, forming a clear product positioning layer covering different demand levels of low, medium and high, allowing customers to quickly match the optimal solution according to their actual needs:

1.27Mm pitch: the core choice for high-density miniaturization

As a representative specification in the field of fine-pitch connectors, 1.27mm pitch products take "extremely compact layout + high-speed stable transmission" as their core advantage. Their pins are made of precision stamping and layout technology to maximize the signal transmission density in a limited PCB board space, while taking into account excellent electrical performance. They are widely suitable for scenarios with high requirements for space and transmission rate.

• Miniaturized consumer electronics devices: such as the charging case of the TWS wireless earphone is connected to the main body of the earphone, the sensor module of the smart watch is connected to the main control chip interface, the eye tracking module of the VR glasses is connected, and the signal interconnection between the main board and the sub-board inside the smart game console, and the camera module. It can support high-speed data transmission, perfectly meeting the transmission requirements of high definition audio, real-time images and other data. At the same time, the low-profile structure of its SMT patch version can effectively compress the internal space of the device and help achieve the ultra-thin design goal of the product.

• Medical precision 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 the zero-delay and distortion-free transmission of diagnostic data and control instructions due to its high reliability (through rigorous environmental testing SET including high and low temperature cycle, humidity alternation, salt spray test) and accurate transmission ability of analog signals. Its exclusive non-magnetic characteristic design can perfectly adapt to the strong magnetic field working environment of medical imaging equipment such as MRI, avoiding interference with image quality.

• Industrial control high-density modules: I/O expansion boards for PLC controllers, signal acquisition modules for industrial IoT sensors, and data collection end points in intelligent manufacturing lines. Double-row 1.27mm products can achieve double the number of signal channels in the same PCB area as a single row. With the strong connection characteristics brought by the installation method of DIP plug-ins, it can withstand mechanical vibration, temperature fluctuations and electromagnetic interference common in industrial production sites, ensuring the stable operation of industrial control systems.

2.00Mm pitch: an intermediate solution that balances performance and cost

As a "transitional" product that connects 1.27mm fine pitch and 2.54mm standard pitch, the 2.00mm pitch specification skillfully takes into account a certain signal density and operation convenience. Its single-pin current carrying capacity can reach 3A, which meets the performance requirements of mid-range equipment while effectively controlling costs. It has formed a significant cost-effective advantage in domestic industrial control boards, mid-range consumer electronics and smart home devices, and is mainly suitable for the following scenarios:

• Mid-range industrial automation equipment: such as the control end point of the food processing line, the signal interface of the small servo driver, and the sorting equipment control module in the warehouse logistics system.
