DESIGN CHARACTERISTICS
• Medium size, environmentally resistant connector
• Recommended operating voltage to 1,000 VAC (RMS)
at sea level
• Quick positive coupling assured by 3 point bayonet
coupling system
• Visual confirmation of complete coupling
• Eliminates mismating by the use of five key/keyway design
• Insertion and removal of contacts from the rear of the
connector assures no damage to the front that might affect
the sealing characteristics
• Utilizes same standard qualified rear-release type plastic
tool for contact insertion and removal
• Contacts are qualified to SAE AS39029** requirements
– BIN coded (three color bands), and are crimped with
standard crimp tools per MIL-DTL-22520
• Grommets are constructed of tear-resistant elastomer
and experience no degradation when exposed to a broad
range of fluids
• Sealing over a range of wire diameters is assured by a
triple webbed grommet at the rear of the connector
• Closed entry socket side of the insert is designed with a
lead-in chamfer and a hard face that will accept a pin
contact bent within pre-established limits
• Elastomer interfacial seal on the pin side has raised
barriers around each pin which displace into the socket
chamfer when mated, providing a positive moisture seal

Wire Stripping
1. Strip wire to required length. (See Figure at right). When
using hot wire stripping do not wipe melted insulation
material on wire strands; with mechanical strippers do not
cut or nick strands.
2. See Table 1 for proper finished outside wire dimensions.
3. Twist strands together to form a firm bundle.
4. Insert stripped wire into contact applying slight pressure until wire insulation
butts against wire well. Check inspection hole to see that wire strands are
visible. If there are strayed wire strands, entire wire end should be re-twisted.
When wire is stripped and properly installed into contact, the next step is to crimp
the wire inside the contact by using the proper crimping tool.

3. Next align the tool and contact up
to the properly identified cavity at
rear of connector plug. Use firm,
even pressure; do not use excessive pressure. It is recommended
to start at the center cavity. Contact
must be aligned with grommet hole
and not inserted at an angle. Push
forward until contact is felt to snap
into position within insert.

Crimping
See table on preceding page for
recommended M22520 series crimping tools,
turret head or positioner selection settings
according to contact size, part number and
wire gauge size.
1. Insert stripped wire into contact crimp pot.
Wire must be visible through inspection
hole.
2. Using correct crimp tool and locator, cycle
the tool once to be sure the indentors
are open, insert contact and wire into
locator. Squeeze tool handles firmly and
completely to insure a proper crimp. The
tool will not release unless the crimp indentors in the tool head have been fully
actuated.
3. Release crimped contact and wire from
tool. Be certain the wire is visible through
inspection hole in contact.

6. Reassemble plug or receptacle hardware
- slide forward and tighten using connector pliers. Connector holding tools are
recommended while tightening back
accessories. When using strain relief,
center wires at bar clamp. Slide clamp
grommet into position and tighten clamp
bar screws. When tightening screws,
pressure should be applied in the same
direction that clamp is threaded to rear
threads of connector. When not using
clamp grommet, build up wire bundle
with vinyl tape so clamp bar will
maintain pressure on wires.

PT-SE, SP-SE, MS/PT-SE
Commercial/MIL-DTL-26482, Series 1
These are a derivative of the PT line, bayonet type.
However, they incorporate crimp contacts that are rear
insertable, front releasable. An MS approved spring tower
retention system holds the contacts in place.
Matrix|Pyle
There are 8 shell styles in the PT, SP and MS/PT series,
and shell sizes are 6-24. The PT solder is UL recognized.
Hermetics are also available.
All miniature circular are intermateable and
intermountable with each other except for the threaded
coupling PC Series.

The SP is a modification of the PT providing special shells
with a wide mounting flange for back panel mounting. The
SP also has a durable non-conductive hard anodic
“Alumilite” coating which provides abrasion and corrosion
protection.
The PC is offered with solder contacts. The PC-SE has
crimp contacts in a spring tower retention system, while
the PC-CE has crimp contacts in a nylon wafer retention
system. Hermetics are available
83723 III
Socket contacts are closed entry design. Printed circuit
board contacts are also available in this series.
PC, PC-SE, PC-CE
Commercial solder and crimp type
The PC series within the Amphenol® miniature circular
family is threaded coupling, rather than bayonet coupling.
The threads are double-stubbed so they can not be
cross threaded.

PT, SP, MS/PT
Commercial/MIL-DTL-26482, Series 1
These are bayonet type with solder contacts. Both the
insert and main joint gasket are molded from resilient
neoprene. This provides excellent moisture sealing at the
gasket and superior electrical isolation of the contact in
the inserts.
PT-CE, SP-CE
Commercial crimp type
Another derivative of the PT line, bayonet type. These also
have crimp contacts that are rear insertable, front
releasable, but the contacts are held in place by a nylon
wafer retention system. The voidless one-piece insert and
grommet assembly provide continuous dielectric
separation between contacts.
