Classic Applications
A high-precision machined circular press-fit terminal with a built-in split female socket (TYZ101-037), designed for solderless, high-performance, and pluggable blind-mating in advanced multi-layer PCB assemblies.
🏗️ High-End Board-to-Board Stacked Modules
• 🔌 Serving as the female mating sockets embedded in an upper logic PCB to accept long header pins from a lower power board.
🚗 Automotive Sensor & Radar Modules
• 🛰️ Solderless interconnection inside LiDAR housings where internal modular components require tool-less pluggable replacement.
⚙️ Military & Aerospace Avionics
• ✈️ Heavy-duty machined pins inside harsh-environment rectangular or circular multi-pin connectors demanding extreme vibration resistance.
🏥 Medical Equipment Interconnects
• 📟 Signal routing inside plug-and-play patient monitoring cartridges or modular scanning sub-systems.
