JRready Deutsch DTM connector kit ST6484 — 2–12-pin housings, 54-pair nickel-plated solid terminals

JRready ST6484 Deutsch DTM Connector Kit is a complete wiring set that supplies DTM housings (2–12 cavities), 54 pairs of size-20 solid male and female contacts, waterproof seals, and a removal tool for reliable automotive and industrial connections. This kit bundles the commonly used Deutsch DTM parts you need for building, repairing, or customizing sealed 20‑gauge wiring harnesses. All connector bodies are molded from PA66 nylon for mechanical strength and environmental resistance; the solid contacts are nickel‑plated for improved conductivity and corrosion protection. Included accessories such as wedgelocks, red sealing plugs and a compact removal tool make the system easier to assemble and service in field or shop environments.

What exactly is included and how many contacts are supplied?

The ST6484 kit provides a selection of DTM connector shells in 2, 3, 4, 6, 8 and 12 cavity configurations, along with wedgelocks and seal plugs to secure unused cavities. You also get 54 pairs of size-20 solid male and female contacts suitable for 20–22 AWG wire, and a Deutsch-style contact removal tool. Everything is designed to let you build multiple connectors without sourcing parts separately.

• DTM connector shells: 2, 3, 4, 6, 8, 12 cavities (PA66 nylon)
• 54 pairs of solid male and female size-20 contacts (20–22 AWG)
• Wedgelocks, red sealing plugs and seal inserts for unused cavities
• Compact contact removal tool compatible with 16–22 AWG stamped contacts

How do the terminals perform and what are they made of?

The kit’s solid terminals are nickel‑plated for wear resistance and stable conductivity, making them suitable for repeated mating cycles and harsh environments. Their solid construction simplifies crimping compared with stamped contacts, producing reliable mechanical and electrical connections when used with an appropriate 4‑indent crimping tool. Nickel plating helps minimize corrosion where exposure to moisture or road salts is a concern.

• Solid (not stamped) size‑20 contacts for consistent crimps
• Nickel plating for corrosion and wear resistance
• Recommended crimp method: professional 4‑indent crimper for best results

Are these DTM connectors waterproof and suitable for outdoor use?

The connector housings are injection‑molded from PA66 nylon and paired with silicone-style seals and red sealing plugs to block unused cavities. Combined, these elements provide protection against moisture and contaminants in many outdoor, automotive, and industrial applications. As with any sealed connector, proper assembly and intact seals are required to maintain environmental resistance.

• PA66 nylon housings resist heat, chemicals, and impact
• Seal plugs and silicone seals protect unused cavities
• Waterproof performance depends on correct assembly and undamaged seals

How do I service or remove contacts without damaging the connector?

The compact plastic contact removal tool included is designed to release stamped and solid contacts safely without harming the wire insulation, seal or housing. Its shape lets you depress the terminal retention tang and extract the contact smoothly, which speeds repairs and reduces the risk of connector replacement. The tool is appropriate for most 16–22 AWG applications encountered with DTM systems.

• Removal tool built for safe, damage‑free extraction of terminals
• Works with 16–22 AWG wires common in DTM harnesses
• Saves time during diagnostics and field repairs

Who is this for? This assembly kit is aimed at electricians, automotive technicians, builders of custom wiring harnesses, off‑road vehicle enthusiasts and small manufacturers who need ready access to sealed Deutsch DTM hardware. It’s useful for anyone who wants a balanced inventory of housings, reliable solid contacts and service tools to build or repair 20‑gauge sealed connections without buying parts individually. For consistent crimps, pair this kit with a JRready 4‑indent crimping tool as recommended.

FAQ

Q: What wire gauge do these terminals fit?

A: The size‑20 solid contacts are designed for 20–22 AWG wire; the removal tool supports 16–22 AWG.

Q: Do the connectors resist water?

A: Housings are PA66 nylon with seals and sealing plugs; correct assembly is required for waterproofing.
