Connectors
Information
Introduction
The D-subminiature is one of the most popular styles of connectors in the I/O category. It is used in computer,
telecom, datacom, medical, and test instrumentation applications as well as in the military and aerospace fields.
Types of D-subminiature connectors manufactured by Cinch
•
Printed Circuit Board connectors:
- Vertical connectors for panel mounting with Dip Solder PC tails.
- Right-Angle connectors for board mounting with Dip Solder PC tails.
Wire Termination connectors for cable assemblies or wire harnesses:
- Crimp and Poke connectors.
- Solder Cup connectors.

D-subminiature contact arrangements - see page 4-5.
Panel mounting specifications/hardware - see page 4-6.
D-subminiature shell dimensions - see page 4-7.
D-subminiature and combo D layouts - see pages 4-5, 4-8 thru 4-10, and 4-56.
General Performance Specifications - see page 4-2.
PCB thickness chart - see page 4-8.
D-subminiature pages are grouped by series. A series is a family of connectors with a similar performance level.
Each series shares a set of features and specifications, from economical and commercial grade product to
high-reliability and military connectors. Each series begins with a page outlining general features and
specifications of connectors, followed by the pages on individual connectors with drawings or features specific
to that connector. Drawings reflect clarifications of dimensions not called out in the information pages of this
catalog. The features of each series can be found in the chart on page 4-4.
Accessories including backshells, junction shells, and hoods as well as hardware can be found on pages 4-80
thru 4-99.
Termination tooling for Cinch connectors can be found at the end of the D-subminiature section of this
catalog on pages 4-100 thru 4-104.

Introduction
All connectors are intermateable with any Cinch D-subminiature of comparable pin count and density, or the
D-sub connector of any other manufacturer complying dimensionally with MIL-C-24308.
Solder terminations and boardlocks meet the requirements for solderability in accordance with MIL-STD-202,
Method 208.
DURABILITY
- Mated connectors are subjected to cycles of insertions and withdrawals specified on the catalog
page. After the prescribed cycles the connectors will meet the Cinch requirements concerning insertion-
withdrawal force, individual contact insertion-withdrawal force, and contact resistance.
APPROVALS
- Most Cinch connectors have UL recognition and CSA approval; however, the specific approvals are listed
on the individual catalog pages.

Cinch connector contacts are generally offered in Gold Flash or 30µin. gold plating for commercial product,
and 50µin. gold plating for M24308 Series Military D-subminiature connectors.
Cinch connectors utilize economical stamped and formed contacts and/or screw machine contacts for
enhanced performance.
Standard density connectors utilize size 20 contacts.
Cinch 1.5 Density Series connectors utilize size 22 contacts for greater density in a standard size
D-subminiature outer shell.
Commercial-grade steel shells are usually available in zinc plating with yellow chromate finish or tin plating.
Tin-plated plugs have grounding indents.
Military grade M24308 Series connector shells are generally steel or in certain cases non-magnetic brass with
cadmium plating and yellow chromate finish.
Insulator materials are glass-filled polyester, glass-filled nylon, and diallyl phthalate.

Introduction
Cinch provides connectors in various footprints, contact diameters, and lengths in both vertical and right-angle
PC mount styles with dip solder tails.
Cinch PCB connectors have metal shells.
Connectors for Terminating Cable Wire
•
Wire Wrap connectors are available in two tail lengths for two-wrap and three-wrap terminations. The contact
is terminated by wrapping wire around it using a wire wrap gun. This connector is especially useful for
prototyping since the wire can be unwrapped and rewrapped if necessary.
Solder Cup connectors allow reliable long-term termination by soldering the wire directly into the connector
contact. Cinch Solder Cups accommodate up to 20 AWG wire.
Crimp and Poke connectors allow the wire to be terminated more economically than wire wrap or solder cup
styles. Contacts are crimped and inserted into the connector. In our D*U Series, the contact is crimped around
the conductor wire. In our D*A Series, the contact is crimped around the wire and the insulation. Crimp and Poke
connectors can be selectively loaded to save labor and material cost.
IDC connectors are an alternative to other types of wire termination connectors. IDC is much faster and very
reliable when all contacts are terminated and the volume is high. IDC utilizes mass termination of the cable wire.
This can save considerable time and expense in the cable assembly process. The estimated time of terminating
two ends of a 25-conductor discrete wire cable with 25-position D-subminiature connectors is about 5-1/2 to 6
minutes less per cable assembly using IDC connectors and Cinch Auto-Clinch termination tooling versus using
Crimp and Poke connectors. This may vary considerably based on the operator, cable wire, and process.
Cinch offers IDC connectors in two versions-for discrete wire or flat ribbon termination.
