BacNav OFS
Outstanding repositionable
backshell for harsh-environment
applications
D
esigned for use in rugged shipboard applications as well as military ground systems
such as armored vehicles, the Glenair BacNav OFS delivers outstanding mechanical,
electrical, and environmental performance. The innovative design incorporates an
environmentally-sealed, EMI shielded core with a locking pivot that facilitates cable
routing and eliminates the need to stock discrete straight, 45° and 90° variants of
standard wire sealing, strain relief, and EMI shield termination backshells. Built to
withstand the handling abuse that topside and below-deck electrical and ber optic
interconnect systems are routinely subjected to by ham-sted sailors and marines, the
BacNav OFS is purpose-designed to deliver life-of-ship and life-of-system performance
and durability. Available
for the broad range
of power, signal, and
ber optic connector
systems—including
MIL-PRF-28876 and MIL-
PRF-64266 (ber optics)
to MIL-DTL-28840,
AS50151, and more—
BacNav OFS meets every
current requirement
for backshell-equipped
connectorized cabling.
Easy repositioning from
straight, 45° and 90°
cable-exit orientations
Submersible performance
without the need for
shrink boots
Durable, flexible EMI/
RFI and environmentally-
sealed core with locking-
pivot Swing-Arm™ frame
Accommodates power,
signal and fiber optic
jacketed cables
Reposition terminated
cables with no impact on
signal integrity or system
performance
Easy repeatable assembly
process using standard
tools
SERIES 390
Designed for above and
below deck shipboard use and
other harsh environmental
applications, BacNav OFS delivers
submersible environmental
protection for electrical and ber
optic interconnect systems.

BacNav OFS is the only fully-sealed
EMI/RFI backshell and strain relief
device that delivers fast and easy
cable angle conguration in the
eld—using a common 7/64” hex
wrench, and without decoupling
from the connector and/or cable.
The exible connector backshell
adjusts to straight, 45° and 90°
cable angles with zero impact
on signal integrity or system
performance.
