The Hirose DX30M-20-CV is a two-piece backshell and cover designed for the DX30 series of 20-position connectors. It wraps the cable exit in a shielded metal shell with a stainless steel and plastic cover, terminating the cable shield at the connector backshell rather than leaving it floating. The 180° cable exit routes the round cable straight out the back, which keeps the assembly profile tight against the panel or enclosure wall. A latch lock on the cover secures the two halves together, and the integrated strain relief clamps the cable jacket so pull forces don't reach the crimp terminals inside the connector.
Shielding and Strain Relief — What's Included
The strain relief is built into the assembly, not a separate add-on; it clamps the round cable jacket at the exit point. For a 20-position cable assembly in an electrically noisy environment, this backshell handles both the mechanical retention and the shield termination in one part.
Hirose has marked the DX30M-20-CV as Last Buy. This means the part is in its final production run — once current stock is exhausted through the channel, it will not be manufactured again. For a BOM that calls this backshell, the procurement window is closing. No official successor part number has been published by Hirose for this backshell.
