Unlock PHD Terminal Connectors
Precision Solution for Industrial Connection

       Today, as electronic devices become increasingly sophisticated, connectors—known as "electronic blood vessels"—play an increasingly crucial role. Having been deeply engaged in the connector field for many years, Guangdong Deke Electric has launched the PHD series of terminal connectors, which have become a benchmark product in the industry, thanks to its excellent manufacturing processes and strict quality control. This article will provide you with a detailed explanation of the technical highlights and application value of this precision connection solution, focusing on three categories: PHD wire harnesses, PHD pin headers, and PHD surface-mount components.

PHD Connector 丨Stable and Reliable HighEfficiency Transmission

PHD Wire Harness  

       PHD Wire Harness, as a key carrier for signal and power transmission, ensures the stable operation of equipment with its excellent performance. It adopts a 2.0mm standard pitch design, which perfectly balances connection density and transmission efficiency. With electrical parameters of 250V rated voltage and 3A rated current, it can meet the needs of the vast majority of industrial and consumer electronics scenarios.
       Its applicable wire gauge range covers 28-22 AWG (with an insulated outer diameter of 0.9-1.5mm). Matched with tin-plated brass terminals featuring a precision crimping process, its contact resistance is as low as below 20mΩ, ensuring the minimization of signal transmission loss. It maintains stable performance in a wide temperature range from -25℃ to +85℃. Combined with the unique anti-vibration structural design of Guangdong Deke Electric, it can eliminate signal interruption issues even in high-frequency vibration scenarios of industrial equipment.

PHD Pin Header

       As the core supporting structure of the connection system, the PHD Pin Header adopts high-quality nylon PA66 insulating material and features a UL94V-2 flame-retardant rating. It can maintain structural stability and electrical insulation performance even in high-temperature environments. The terminals of the Pin Header are made of high-elasticity phosphor bronze and processed with a precision tin-plating technique, which not only ensures sufficient electrical conductivity but also significantly enhances corrosion resistance and mating cycles.
      The PHD Pin Header adopts a 2.0mm standard pitch design and offers a variety of pin count configurations, ranging from 2×2P to 2×22P, to meet the connection requirements of different devices. Its through-hole mounting structure design makes the assembly process simple and efficient. With an insulation resistance as high as 1GΩ or more, it effectively prevents electrical leakage and signal interference.

PHD SMD

        Addressing the connection needs of miniaturized and high-density electronic devices, the PHD Surface-Mount Series utilizes advanced SMT (Surface-Mount Technology) to provide efficient connection solutions for microelectronic devices. The insulators are made of high-temperature-resistant PA9T material, which can withstand the high-temperature reflow soldering process without deformation, ensuring stable and reliable soldering quality.
      The PHD Surface-Mount Connectors also maintain a 2.0mm standard pitch, with a pin count range from 2×2P to 2×22P, meeting connection needs of different densities. Compliant with the RoHS environmental standard, they balance environmental requirements while ensuring performance. Additionally, their precision positioning design and excellent flatness control ensure a high yield rate during the surface-mount process, making them highly suitable for large-scale automated production.

PHD Series Terminal Connectors

Technical Advantages and Selection Value

       Compared to traditional connectors, the core advantage of the PHD Series lies in balancing high density and high reliability: The 2.0mm pitch design saves 40% of installation space compared to the conventional 3.5mm pitch, while the dual-row arrangement doubles the number of interfaces within the same area. For devices requiring multi-channel signal transmission (such as multi-parameter sensor arrays in medical testing instruments), the 34-pole model can significantly reduce the number of connectors used, simplifying the device structure.
       In practical applications, this series supports both through-hole and right-angle soldering methods. When paired with specialized crimping tools (such as PCR-04 AB), it enables efficient assembly, reducing labor costs in mass production. Whether in precision assembly of consumer electronics or rapid maintenance in industrial sites, the PHD Series provides suitable connection solutions.
