Suggested Strain Relief - Insert Arrangements 9-5 or 19-18
with Quadrax Contacts
Due to the piggyback grommet interference with normal strain reliefs
on the shell size 9 only, the recommended strain relief for the connec-
tor is: Amphenol part number TGW-R-5309-10 (OD Cad) or TGF-
R-5309-10 (Electroless nickel)
.367 MAX.
- shell size 9 only. For 19-18 insert
.525
pattern, recommended backshell:
MAX.
Glenair 367-221-NF. This is
recommended due to the proximity
of the size 8 contacts in relation
to the shell.
