MIL-C-28840 connectors were developed for the navy, for use with jacketed cable in shipboard applications. They are a high density circular connector series utilizing a high shock threaded coupling system with front release crimped contacts.

For these connectors dmc has added a new crimping tool to its range, the M22520/34-01 and other tools as follows:

The DMC GMT232 hand crimp tool, qualified to M22520/37-01 standards, is designed specifically for M81824/1, /6, /7, /8, /9, /10, /11, /13, & /14 environmental splices. It's the go-to choice for crimping low-profile environmental splices, including those designated as M81824/1.

Popular among professionals, the GMT232 covers a wide range of splice sizes—12 (yellow), 16 (blue), and 20 (red)—making it versatile for various low-profile environmental splice applications. Its unique locator feature ensures precise positioning of the splice during wire termination, akin to the functionality of the well-known Tyco AD1377.

Specifications:

• Qualification: Mil-Spec/AS Qualified
• Crimp Applications: Splices
• Crimp Tool Type: GMT/PMT Tools
• Power Type: Manual
• NSN: 5120011208721, 5120013619615
• Shipping Weight: 1.15 lbs

DMC AFM8 tool, which is designed for crimping miniature and sub-miniature connector types commonly used in electronic systems. The tool is qualified to MIL-DTL-22520/2 and AS22520/2 standards, accommodating wire sizes ranging from 20 to 32 AWG.

The AFM8 provides a Mil-Standard 8 impression crimp, ensuring maximum tensile strength, and features a cycle-controlled precision ratchet for consistently accurate crimps. It includes a built-in 8-step selector knob for easy adjustment of the crimp depth setting.

Positioners are available to adapt the tool frame to specific applications, with each positioner designated for particular wire sizes and indicating the selector position. Periodic gaging with the M22520/3-1 "GO/NO-GO" gage is recommended for accurate calibration.

The tool kit, DMC274, contains the AFM8 tool frame, tool gage, mil-spec positioners, instruction sheets, and a tool selection chart. The AFM8 is manual and requires no operator maintenance other than keeping it clean and properly stored when not in use.

Here are some key specifications:

• Wire Range: 20 - 32 AWG
• Qualification: MIL-DTL-22520/2* and AS22520/2*
• Crimp Tool Type: Indent Tools
• Power Type: Manual
• NSN: 5120013358572, 5120001653910
• Shipping Weight: 0.75 lbs

It seems like a versatile and reliable tool for crimping a variety of wire sizes commonly found in electronic systems.

Qalified to mil-dtl-22520/7*, the DMC MH860 is a recent addition to the military specification. It was developed to meet the demonstrated need for supporting the majority of electrical systems with one versatile crimp tool frame.

The mh860 accepts the entire middle wire range of 16 through 28 awg, with positioners which adapt it to virtually all applications consistent with others in the mil-dtl-22520 family.

Pneumatic versions of this tool can be found here.

The dmc123 tool kit contains the mh860 tool frame, tool gauge, and all mil-spec positioners.

Also included in the dmc123 are tool instruction sheets and a tool selection chart.

The DMC HX4 and HX3 series crimp tools feature a system of interchangeable dies which eliminate the need of separate fixed die crimp tools for each and every different application. Many maintenance and manufacturing concerns have standardized on one of these models, thus eliminating the cost associated with maintaining and calibrating bulky inventories of single purpose tools.

Tremendous flexibility and cost advantages exist with this crimping system due to the wide variety of interchangeable dies which are available for these tool frames. As new requirements evolve, a new set
of dies is all that’s required to meet the demand. A truly modern concept which will not require major change with time…only simple additions.

Crimping dies are snapped into the tool frame and retained in place by internal spring clips. They may be permanently secured, if desired, by driving a roll pin into the holes provided.

The tool frames are equipped with a positive ratchet assembly which controls complete handle movement in both directions.

Qualified to Mil-DTL-22520/2*, the dmc afm8 is designed for most of the miniature and sub-miniature connector types that are so widely used in electronic systems. The afm8 meets the need for a miniature tool accommodating wire sizes 20 through 32 awg.

The AFM8 gives a mil-standard 8 impression crimp, which assures maximum tensile strength. The cycle controlled precision ratchet assures consistently accurate crimps every time. The tool frame has a built-in 8 step selector knob for ease in dialing the correct crimp depth setting for the wire being used.

Positioners adapt the tool frame to a particular application. The data plate on each positioner designates which contacts the positioner accommodates for its wire size and indicates selector position. The positioner is easily removed and changed.

Periodic gaging is recommended to insure accurate calibration. This is easily accomplished with the m22520/3-1 “go/no-go” gage (dmc part no. G125) on sel setting #8. The afm8 is 6 3/4" in length and weighs approximately 10 oz.

Other than keeping the tool clean and properly stored when not in use, no operator maintenance is required. Pneumatic versions of this tool can be found here.

The DMC274 tool kit (pictured right) contains the AFM8 tool frame, tool gage, and all mil-spec positioners. Also included in the dmc274 are tool instruction sheets and a tool selection chart.

DMC is dedicated to serving the connector tooling needs of the electronics industry. we, therefore, top off our product package with a wide variety of installing and removal tools.

Although we supply both plastic and metal tools, we recommend the use of the metal tools because of their durability.

When used properly they are more cost effective in that they withstand thousands of contact insertion and removal cycles. The trend to all metals tools is being actively encouraged by most departments of the government.

DMC installing and removal tools are of proven high quality and reliability. in addition to the tools listed in these reference table, we have many more for other connector applications. please contact us for more details.

DMC’s general purpose insertion and removal tool kit (p/n: dmc1155) contains metal insertion and removal tools for common mil-spec circular connectors, d-sub miniature connector, arinc connectors and as81714 terminal junctions. Consult dmc for further details.
