Introduction
Cinch Dura-Con
TM
connectors are designed for applications that require a rugged, durable, and high-performance interconnect.
Dura-Con is the ideal connector for applications where weight and space must be kept to a minimum while maintaining maximum
reliability. Miniaturized airborne electronics and data processing equipment, where shorter signal paths are needed, represent
typical applications for these unique connectors.
The heart of the Dura-Con system is the Dura-Con pin contact. The Cinch Dura-Con pin contact is made from a precision minia-
ture spring cable with a welded tip. The expanded cable provides seven spring members peripherally around the pin so that con-
tact is maintained with the mating socket wall no matter what radial forces are applied. This spring may be flexed many times
without any evidence of metal fatigue. Reliable mating is further ensured by protecting the pin contact in a tightly toleranced
recessed cavity.
Cinch’s family of Dura-Con connectors includes MIL-C-83513 Series connectors along with our own commercial equivalents.
The commercial Dura-Con product line offers an expanded range of termination and hardware options for all-plastic and metal
shell wire versions and right-angle and straight PC board mount “terminal blocks”. Cinch also packages the Dura-Con contact
in a very low profile plastic strip connector on .050" centers and in a line of high-density microminiature edge (Microedge) board
connectors that meet the requirements of MIL-C-55302. Cinch has created a line of plastic and metal shell Dura-Con
connector savers for very high mating cycle applications such as test equipment.
Termination Options:
Cinch offers the following termination methods for its Dura-Con connectors:
Insulated Wire - Insulated wire is crimped to the Dura-Con contacts then epoxy backpotted at the factory. Wire is available in
standard lengths of 18, 24, 36, and 48 inches.
Uninsulated Wire - 24 AWG, gold-plated, uninsulated wire is crimped to the Dura-Con contact at the factory. Wire is available in
standard lengths of 0.5, 1.0, and 2.0 inches. This option allows the user greater flexibility when installing the connector.
Solder Cup - For applications that require the lowest contact resistance, Cinch offers Dura-Con connectors with solder cups for
termination by the user.
