Specification according to component manufacturer


Mini Coax has several interfaces. The most established ones are MATE-AX (by TE Connectivity) and HFM (by Rosenberger). The two connector systems are not mating-compatible with each other.

There are 1-, 2-, 4- and 6-pin housings.

For Mini Coax systems, common automotive Coax cables (RG174, RTK031, etc.) can be used.

In case of an unsealed variant, a partial assignment is possible. In case of a sealed variant, the unassigned cavity must be filled with an appropriate sealing element, a so-called ‘blind plug’.

Handling instructions for Mini Coax connector systems are available. They can be found under the following link.
