Radiall QM Series Connectors

QM – Quick-Mount – Connectors are Commonly Used in Commercial and Private Jets

QM series has a compact design, high-performance and quick installation attributes. Generally used in civil aviation and business jets applications. QM connectors series comes in various shell options: QM size A and size B in order to improve density and weight requirements in the wiring processes. QM shells offer broad spectrum of mounting device. QM series is a budget friendly option since it uses EPX contacts a variety of modular inserts.
