CRB — Rectangular Backshell
Rectangular backshells for Micro-D, micro crimp and D-Sub connectors
The backshell is the component that manages the cable exit from the connector. On rectangular connectors, the variable that matters is the exit geometry: top, side, 45°, dual, elliptical or split.
- Three series: CMH Micro-Hood, C7H and C2H
- Twenty-one exit configurations in the catalog
- For MIL-DTL-83513 (Micro-D), special micro crimp and D-Sub M24308 High Performance connectors
- Six finishes, operation up to +200 °C · ITAR EAR FREE
CRB series
Rectangular Backshell — three series
For rectangular connectors. Here the variable isn’t sealing but the exit geometry: top, side, 45°, dual, elliptical or split. Twenty-one configurations in all across the three series.

Materials and finishes
Six finishes, each with its own application
The finish determines conductivity, corrosion resistance and operating temperature. The CRB catalog matches each one to its typical applications.
Rectangular backshells — 6 finishes
Electroless nickel
EN−65…+200 °C
Excellent conductivity and wear resistance. Used in avionics boxes, exoatmospheric equipment and missiles.
Passivated stainless steel
SS−65…+200 °C
Maximum strength and corrosion resistance. Aircraft engines, landing gear, armored vehicles, marine applications.
Black zinc-nickel
BN−65…+175 °C
RoHS-compliant, approved for MIL-DTL-38999 and AS85049 as a replacement for cadmium and hexavalent chromium. Backward-compatible with cad-plated accessories.
High-phosphorus nickel
PN−65…+175 °C
Up to 1000 hours of salt spray when deposited over electroless nickel. Highly conductive, good lubricity.
Olive drab cadmium
CO−65…+175 °C
Up to 500 hours of salt spray over electroless nickel. The long-standing defense and aerospace standard.

Applications
Where these components end up
The backshell catalog does not list industries for the product line itself: it lists the CPE Group’s industries and the programs in which its products have been used. We report both, adding nothing.

Let’s check compatibility together
With the connector part number and the exit configuration you need, we can confirm the exact part number. If what you need isn’t in the catalog, we’ll tell you right away — and assess whether it makes sense to build it to specification.
