Amphenol broadens their Miniature Cylindrical Family of
Connectors with the addition of the Matrix^® Product line
of MIL-C-26482, Series 2 connectors.
This series provides a bayonet coupling connector with crimp
rear insertable, rear releasable contacts.
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 con-
nector 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 MIL-C-39029 requirements – BIN
coded (three color bands), and are crimped with standard
crimp tools per MIL-C-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 tri-
ple 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 con-
tact bent within pre-established limits
• Elastomer interfacial seal on the pin side has raised barri-
ers around each pin which displace into the socket cham-
fer when mated, providing a positive moisture seal
CUSTOMER OPTIONS

Wall mount with either a narrow or a wide flange, jam nut

gers, in shell sizes 8 to 24
