D-subminiature Connectors Introduction Information 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. - Insulation Displacement connectors IDCS to terminate discrete wire or flat cable. - Wire Wrap connectors. How to read this section The information pages provide standard data common to all D-subminiature connectors. These include: - 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 4 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.

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. CONTACTS - Cinch connector contacts are generally offered in Gold Flash or 30in. gold plating for commercial product, and 50in. 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. METAL SHELLS - Commercial-grade steel shells are usually available in zinc plating with yellow chromate finish or tin plating. 4 - 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. The connectors are usually available in plugs and sockets in 9, 15, 25, 37, and 50 position sizes. Call Toll Free: 1 (800) 323-9612 4-2
