This document introduces the specifications of the KGV series round connectors, including connector type, temperature range, materials, mechanical data, electrical data, etc.
The KGV series from Lumberg are circular connectors with a threaded joint (IEC 60130‑9) and IP 40 protection, designed for back‑side mounting. The document provides temperature ranges, material options, mechanical forces, and electrical contact data for 3‑ to 12‑pole variants.
Key information includes insertion and withdrawal forces, contact resistance, material finishes (CuZn pre‑silvered/gilded, Zn die‑cast), and ordering designations for each model (KGV 30, 40, 50, 60, 70, 71, 80, 120). This manual is written in German.
