Solderless D‑Sub Terminal Connectors (sizes DB9 to DB78) Key benefits Fast, tool‑friendly installation: solderless design saves time and reduces assembly errors during prototyping, repairs, or production runs. Reliable signal and power contacts: gold‑plated pins minimize contact resistance and corrosion for stable connections in data and control circuits. Safe and durable construction: metal terminals combined with insulated, flame‑retardant housings provide mechanical strength and meet industrial safety requirements. Broad compatibility: available in standard D‑Sub sizes from DB9 up to DB78 to match common serial, parallel and custom interface needs. What this product solves Eliminates the need for soldering, speeding up field service, system integration, and iterative development. Improves long‑term connection reliability in communications and industrial environments through corrosion‑resistant plating and a sturdy terminal design. Simplifies wiring and reuse with easy insertion/removal of conductors and robust housings that protect contacts from mechanical stress. Key features Solderless terminals for quick assembly and rework Gold‑plated pins for low contact resistance and corrosion protection Metal contact terminals for mechanical durability Insulated, flame‑retardant housings for safety and electrical isolation Size range: DB9 through DB78 to cover common D‑Sub configurations Typical applications Industrial control panels: quick replacement and field wiring for PLCs, I/O modules, and machine interfaces. Communications equipment: reliable serial and parallel connections in routers, test equipment, and telecom racks. Engineering and hobby projects: rapid prototyping and custom cable assemblies for lab work, sensors, and embedded systems. Why choose these connectors Practical engineering choice for technicians and designers who need dependable, easy‑to‑use D‑Sub interfaces without soldering. Built to integrate into existing systems with standard D‑Sub form factors while offering improved durability and safety features.
