HIGH-PERFORMANCE ALTERNATIVE TO OLDER MIL-DTL-5015 SOLDER TYPESThe Amphenol MS3450 MIL-DTL-5015 Rear-Release Threaded (Matrix®) series connectors use rear-release crimp contacts with a retention clip. These Amphenol connectors fill the gap between older MIL-DTL-5015s and the environmental and higher-performance needs of new technologies. They are sealed to withstand moisture, condensation, vibration and flash-over. Over 165 contact layouts are available, in variations that allow for just power, just signal, or a mix of both contact types. These were formerly MIL-C-5015. For more detailed product information on MS3450 series connectors, please see the specifications below.
Get shopping! Mil spec part number prefixes include MS3450, MS3451, MS3452, MS3454, MS3456 and MS3459.

AMPHENOL MS3450 SERIES FEATURES
- Broad Operating Temperatures
The electroless nickel plating and stainless steel shell connectors will operate in temperature ranges from -75°F to +392°F (-55°C to 200°C). The cadmium olive drab plating connectors will operate in temperatures ranging from -75°F to +347°F (-55°C to 175°C).
- Environmental
These connectors will perform in the full range of operating conditions defined in MIL-DTL-5015 and are recommended for conditions where vibration, moisture, pressure, and/or temperatures are extreme.
- Rugged Shell
The rugged aluminum alloy or steel shell are highly resistant to damage and corrosion with firewall capabilities. Shells are available in four different styles, like a self-locking coupling nut in seventeen different sizes.
- Wide Range of Wire Gauges and Current-Carrying Capacity
Up to 150 amps for standard military contacts and wire gauges from size 20 to size 0 AWG.

AMPHENOL MS3450 SERIES WIRE-STRIPPING AND CONTACT-CRIMPING
.245 (6.2) for #16/16S Contact .465 (11.8) for #8 Contact .540 (13.7) for #0 Contact
.245 (6.2) for #12 Contact .465 (11.8) for #4 Contact
STEP 1: Strip wires. (See above for correct strip length by contact.) Insert wire into rear of contact. Wire insulation must push against rear of contact. Wire must be visible through inspection hole.
STEP 2: Use M22520/1-01 crimp tool with proper crimp locator M22520/1-02. Click here for additional tooling.
STEP 3: Insert contact and wire into tool jaws. To crimp, squeeze handles together fully until ratchet releases and allows handles to expand, otherwise contact cannot be extracted from tool jaws. Maintain slight insertion pressure on wire while crimping contact to wire.*
AMPHENOL MS3450 SERIES CONTACT INSERTION
STEP 1: Remove backshell and put wired contacts through cable clamp opening.
STEP 2: Use colored end of CIET tool for insertion. Place wire into tool at large opening. To facilitate contact insertion, a six-inch minimum of free wire is recommended.
STEP 3: Slide back tool on wire while holding thumb against wire at opening. Wire will slip into tool.
STEP 4: With tool pressed against shoulder of contact, starting at the center cavity, insert wired contact and tool into properly-identified cavity at rear of plug with firm, even pressure. Do not use excessive pressure.
STEP 5: When contact touches bottom, a slight click can be heard as tines of metal retaining clip snap into place behind contact shoulder.
STEP 6: Check face of plug or receptacle for proper contact installation. In socket inserts with a large number of contacts, cavities are identified in a spiral pattern. A projecting line from the spiral indicates omission of a letter; a broken circle around a cavity indicates transition between capitals, and lower case and double letters.
STEP 7: Withdraw tool from rear of plug. To be sure that contact is locked, pull back lightly on wire. Remove tool from wire and proceed with other contacts.
STEP 8: After all contacts are inserted, fill unwired cavities with sealing plugs (insert head first and leave end protruding for ease of removal), assemble backshell on rear of connector.
* IMPORTANT NOTE: Microsection the contact to verify crimp quality.
AMPHENOL MS3450 SERIES CONTACT EXTRACTION
STEP 1: Remove backshell and slide back along wires to allow access. To extract a contact, use white end of CIET tool. Place wire into tool at large opening. Slide back tool on wire while holding thumb against wire at opening. Wire will slip into tool.
STEP 2: Push tool into rear of plug until it touches bottom. At this point, tool releases tines on retaining clip so that contact can be extracted.
STEP 3: While maintaining slight insertion force on tool, firmly hold wire against serrated shoulder at center of tool and extract both wired contact and tool from plug.
Note: LJT Series shown.
