HRS DF56-50P-0.3SD: Technical Value Analysis of High-Density Ultra-Fine Coaxial Micro Interconnection Components

In high-end applications such as intelligent devices, medical imaging, and drones, the combination of ultra-fine coaxial cables and high-end miniature interconnect components often has a higher cost than that of ordinary cable assemblies. This is not only due to the cost of materials and processes, but also closely related to high-frequency high-speed signal design, reliable locking mechanisms, and strict environmental certifications. HRS DF56-50P-0.3SD is a representative of this, with its technical details being the core support for high-value applications.

Part 1: Technical Features

DF56-50P-0.3SD belongs to the HRS DF56 series of 50-pin miniature components, with a pitch of only 0.3 mm, an rated current of about 0.5 A, and a voltage up to 50 V. The contact is gold-plated with a thickness of about 0.10 µm, and is installed using a tin-welded wire method, ensuring good contact and corrosion resistance. The design with a 1.25 mm mating height and a 2.6 mm depth is suitable for extremely small spaces, and the vertical mating method between the board and the wire enhances installation reliability, making it particularly suitable for space-sensitive applications such as smart glasses and folding hinges.

The reasons behind high quotations

The ultra-thin coaxial cable and DF56 series components are expensive, mainly due to various factors. Micro coaxial cables use AWG42-46 ultra-fine wire gauges, combined with multi-layer shielding and compact geometrical structures, which require extremely high manufacturing accuracy. Precision contact processing, reliable locking, and anti-vibration design increase costs. At the same time, high-frequency signal transmission requires strict impedance matching, shielding, and grounding design. Added to this are RoHS halogen-free certifications, high-temperature resistance, and supply chain limitations, which make the unit price significantly higher than that of ordinary cable components.
