Mounting Recommendations
for miniature cylindrical connectors
FLANGE MOUNTED CONNECTORS
All flange mounting PC and PT connectors use standard MS
mounting dimensions. They cannot be back panel mounted
due to coupling clearance. The PTB (thru-bulkhead) type con-
nector must also be back panel mounted on one side. Flange
gaskets are available for both series, see page 64.
JAM NUT MOUNTINGS
The jam nut design has become very popular because it allows
bench wiring of harness assemblies. The labor saving often off-
sets the added cost of the jam nut receptacle which is due to
the self contained “O” ring and the extra nut. The PC series
mounts in a round hole and can be pinned to prevent rotation.
The PT series mounts in a “D” mounting hole and does not
require pinning.
HERMETIC RECEPTACLE MOUNTINGS
This series must be mounted in such a way as to preserve the
hermetic seal provided by the glass insert. Mounting data for
box and jam nut receptacles is given above. Cut-out required
for solder mounting receptacles (N) is given below.

The finish of each of these hermetic
receptacles is fused electro-deposited
tin for easy solderability, and protected
by a special lacquer for optimum shelf
life. The lacquer will not interfere with
any soldering operation.
Low temperature solder should be used
and the addition of a solder fillet at
arrow points on drawing at right is rec-
ommended. Care must be taken that
the operating temperature of the final
assembly does not rise above the melt-
