This is a circular connector with screw lock and solder terminals for front panel mounting.
The KFV series from Lumberg comprises circular connectors designed for front‑mounting with a threaded joint (IEC 60130‑9) and IP40 protection. The handbook lists the available pole configurations (3‑8 and 12 poles) and the compatible plug part numbers (033098, 033099, SV, WSV).
Key specifications include a temperature operating range of –40 °C to +85 °C, contact resistance below 5 mΩ, insertion force under 5 N for 3‑8 pole contacts, and withdrawal force above 1.2 N. Materials are specified as a Zn die‑cast housing with copper and nickel plating, and contact bushes of CuZn that are pre‑silvered or pre‑nickeled and gilded. This manual is written in German.
