IEEE 1394 Connection System
for Harsh Environments
Description
FW Field allows you to use a standard IEEE1394 connection
in harsh environments:
• Sealed against fluids and dusts (IP67)
• Shock, vibration and traction resistant
• No timely in-field cabling operation necessary
• No assembly tools required
• Improved EMI protection
With FW Field, you can insert most
standard IEEE 1394
cordsets
into our metallic plug shell to protect it from
shocks, dust and fluids.
No hazardous in-field cabling and grounding required!
FW FIELD TV
Transform your IEEE 1394
cordset into a Harsh
Environment Connector !
The metallic plug connects into the receptacle using a
Tri-Start Thread coupling mechanism (MIL-DTL-38999
series III type) with an anti-decoupling device for high
vibrations.
On the receptacle side, an IEEE 1394 receptacle is
soldered onto a PCB with the following back
terminations:
• another IEEE 1394 receptacle
• solder board with 6 tined holes to solder your wires
Standard cordset shielding is transmitted to the IEEE
1394 receptacle through grounding fingers.
For added EMI protection, the shells are conductively
plated (Ni, Cd) and have metallized receptacle inserts
which transmit the shielding to the connector shells and
then the panel.

Assembly Instructions
Plug Assembly
1.
If a fully sealed (IP67) assembly is required: Install the
white tape around the plug to cover the 4 holes of the
overmolding. If there are no holes omit this step.
Insert the black O Ring around the front face of the IEEE
1394 plug. This O Ring will ensure the seal.
Insert the IEEE 1394 cordset into the metallic backshell.
Insert laterally onto the cable the retention spacer (this
spacer is soft so as to adapt to various overmolding styles)
and slide the IEEE 1394 plug into this retention spacer.
Insert the friction ring laterally onto the cable cordset.
Insert the IEEE 1394 plug into the metallic circular shell.
Note at this step that the main key is used for polarization.
Screw the backshell on the plug body. A spanner may be
required to fully close the backshell to the circular shell.

Important Note
: The sealing of the connector is not done by the
black retention spacers which are sloted, but rather by the
front face O-Ring (Fig 2).
