2. Flame resistant
3. Backplane
Satisfies flammability rating UL94V-0
MU Backplane connector has a self-holding mechanism which does not transfer any force on the back panel when
both side of connector assemblies are fully connected. Back panel side connectors can be removed or inserted
even both sides are mated.
