Appendix C: Guidance for the use of 90° Backshells
It is important when specifying connector backshells that the correct backshell is used according
to the application and cable routing. If the correct backshell is not used it could cause damage to
the cables and put undue stress on the contacts. This in turn could affect its performance or
shorten the service life of the connector.
When routing cables through a 90° bend behind the c onnector. It is important to use a 90° outlet
for this purpose.
While it is recommended that a 90° outlet is used i n all such applications. This document provides
a guide to the minimum bend that can be applied to a cable without the use of the correct
backshell.
The bend radius shown is through the centre of the connector body.
It is important to note that the bend radius shown is for the connector in it’s uncoupled state as
when the connector is uncoupled it reduces the bend radius of the cables.
