CONNECTORS
The connectors used on the data logger are commercial versions of the MIL-C-26482
Series 1 family of connectors and are compatible with their military equivalents.
All pin-out diagrams on the following pages show the face of the chassis connector.
This is the same as the back of the mating cable connector.
There are several different manufacturers of connectors that will mate with the data
logger connectors, but not all manufacturers make all of the pin-out variations. The
part numbers we specify below are for Souriau connectors with solder cup
connections. Crimp connections are also available, but do not order these unless you
have the proper assembly tools.
Be particularly aware of problems in the 8-3 family, there are some variations that
look like they should mate, but the pins are in slightly different positions.
There are several different styles of environmental sealing, depending on the type of
wire used. The part numbers we have specified are for sealing to jacketed cables.
There are also types that are for loose wire bundles and thus seal the individual
wires, or are intended for potting. Not all manufacturers make all variations in sealing,
so check the catalog very carefully before ordering a different brand. The true military
equivalents usually do not seal to jacketed cable -- check with your supplier. Note
that individual wire seals require wires of a specific diameter to work.
Delivery can be slow from the suppliers -- there are so many possible variations of
these military style connectors that the suppliers often stock the raw parts and then
assemble the ordered combination when they get an order. Please call FTS for a
quote if you require connectors as FTS usually has a supply of connectors readily
available in our stockroom.
Warning:
If you are soldering wires to the connector, make sure you clean the flux off the
connector after soldering. Any moisture present inside the connector will combine
with the flux and cause corrosion and so failure of the connection will result. Water
soluble and no-clean fluxes are particularly bad in this respect.
Part number example:
851-06JC10-6PN50
851 Souriau series designation for this family of connectors
06 cable connecting plug (i.e., plugs into the datalogger connectors)
JC seals to jacketed cable, with cable clamp
10 shell size (connector diameter)
6 contact arrangement (6 pins in hexagon)
P pins (as opposed to sockets)
N insert not rotated (this is left out of the part number printed on the
connector)
50 Souriau series index
In general, all of the connectors will be of the form 851-06JCxx-xxYN50 where xx-xx
is the shell size and contact arrangement, and Y is the pin (P) or socket (S)
descriptor. This cable end connector is equivalent to MS3116Fxx-xxYN except that
the military has individual wire seals instead of sealing to jacketed cable. Check with
your supplier to see if a jacket seal is available.
