Core Components Breakdown:Exquisite Craftsmanship, Each Showing Its Prowess

（一）Technical Parameters: Reliability Defined by Data

      The HY2.0 Series Terminal Connectors build their core competitiveness on precise technical parameters. Featuring a standard 2.0mm pitch design, this series ensures compatibility with mainstream equipment in the industry.
      In terms of electrical performance, it boasts a rated current of up to 3A and a rated voltage of 250V AC/DC, with contact resistance controlled within 20mΩ and insulation resistance exceeding 1000MΩ. These parameters jointly guarantee stable and efficient signal and power transmission.
      Temperature adaptability is a key indicator for industrial-grade connectors, and the HY2.0 Series performs exceptionally well. Its operating temperature range covers -25℃ to 85℃, enabling it to adapt to various scenarios from cold regions to high-temperature industrial environments.
      In terms of mechanical durability, the series adopts high-quality tin-plated phosphor bronze terminals, combined with UL94 V-0 flame-retardant nylon housings. This design not only provides excellent anti-oxidation performance but also maintains structural stability in extreme environments.

（二）Upgraded HY Fully Enclosed Terminal: More Stable, More Reliable, More Secure

      The "HY Fully Enclosed Terminal" stands out uniquely in design,  adopting an advanced fully enclosed structure. This structure is like putting a sturdy "protective shield" on the terminal, enabling it to handle various complex environments with ease.
      Whether in harsh conditions such as high temperature and high humidity, or in industrial environments with strong electromagnetic interference, it can maintain connection stability—free from issues like loosening or disconnection—providing reliable assurance for the continuous and stable operation of electrical equipment.
      Internally, it features a high-precision wire crimping structure that firmly secures wires, effectively reducing the problem of increased contact resistance resulting from loose wires. Even when equipment undergoes frequent startup and shutdown, or when there are severe current fluctuations, it still maintains a stable connection state, ensuring smoother operation of your electrical system.

（三）HY2.0 Pin Header: A Stable and Reliable Connection Base 

      As the fixed base of a connector, the pin header is a key component for ensuring connection stability. The HY2.0 Pin Header offers a variety of specifications ranging from 2P to 16P, and its innovative bent-pin design with a latch effectively addresses the issue of poor contact common in traditional connectors.
      The latch structure ensures precise positioning during the insertion and removal process, reducing poor contact caused by vibration or incorrect operation. This design is particularly crucial in precision equipment such as scanners and automotive electronic control modules.
      Adopting a single-row arrangement, the pin header supports right-angle (90°) mounting, which greatly enhances the flexibility of PCB layout.

（四）HY2.0 SMD: An Efficient and Precise Surface Mounting Solution 

      As the fixed base of a connector, the pin header is a key component for ensuring connection stability. The HY2.0 Pin Header offers a variety of specifications ranging from 2P to 16P, and its innovative bent-pin design with a latch effectively addresses the issue of poor contact common in traditional connectors.
     The latch structure ensures precise positioning during the insertion and removal process, reducing poor contact caused by vibration or incorrect operation. This design is particularly crucial in precision equipment such as scanners and automotive electronic control modules.
      Adopting a single-row arrangement, the pin header supports right-angle (90°) mounting, which greatly enhances the flexibility of PCB layout.

HY2.0 Free-Hanging Connector

Flexible and Convenient On-Site Assembly Option

HY Free-Hanging Technical Parameters: Reliability Defined by Data

      As a basic connection unit, the HY Free-Hanging offers multiple position options ranging from 2 to 20. It adopts PA66/UL94 V-0 nylon housings, with pre-designed precise terminal mounting positions inside.
      This design not only ensures flexibility in on-site assembly but also prevents wiring errors through its standardized structure. With a contact resistance of ≤ 30mΩ and insulation resistance of ≥ 1000MΩ, it operates stably within a wide temperature range of -40℃ to 105℃. The tin-plated phosphor bronze terminals endow the product with excellent anti-oxidation performance.
      Additionally, its quick mating/unmating design enhances assembly efficiency and effectively reduces labor costs. The elastic structure of the contact points ensures tight and reliable connections, while its excellent anti-disconnection performance guarantees connection stability during use.
