JRready Solid Pin Contacts Size 20 Purple Stripe, 50 Pairs — Tin‑Bronze Nickel‑Plated, 7.5A Crimp

These purple-striped, size 20 solid pins from JRready are made to fit DTM, Strike, HDP20, HD30, DRB and DRC series housings. Each pack includes 50 pairs (100 individual contacts) plated with nickel for corrosion resistance, and manufactured from tin bronze to improve conductivity and contact stability compared with basic brass. The contacts are optimized for crimp applications and rated for up to 7.5 A when crimped correctly to 16–22 AWG conductors.

How are these contacts best installed?

Proper crimping is the key to dependable performance. JRready recommends a four-indent crimp tool and professional crimping technique to achieve the tensile strength and electrical continuity these solid pins are engineered for.

• Use a dedicated four-indent crimp tool sized for size 20 contacts.
• Strip the conductor to the recommended length before inserting into the contact.
• Inspect crimps for correct compression and no wire strand splaying.
• Verify engagement with the mating housing after crimping to ensure retention.

What electrical and mechanical limits should I expect?

Each contact carries a maximum current rating of 7.5 A when used within the specified 16–22 AWG range. Mechanically, these contacts have demonstrated durability through repeated mating cycles.

• Current rating: 7.5 A (with correct wire gauge and crimp).
• Wire compatibility: 16–22 AWG solid conductors.
• Mating durability: no electrical or mechanical defects reported after 100 engagement cycles.
• Plating: nickel over tin bronze for wear and corrosion resistance.

Which connector families and applications match these pins?

These solid pins were produced to be compatible with several common automotive and industrial connector lines, making them appropriate for sensor, lighting, handheld, and control-panel wiring where DTM-style connectors are used.

• Compatible housings: DTM, Strike, HDP20, HD30, DRB, DRC series.
• Typical uses: vehicle wiring harnesses, sensors, diagnostics, and custom assemblies.
• Best with solid-core conductors for stable crimps and retention.
• Not recommended for loose-stranded cable without verifying crimp method.

How do material and plating affect performance?

Tin bronze provides better conductivity and mechanical stability than standard brass, while nickel plating adds an extra layer of protection against corrosion and wear. Together they help maintain low contact resistance and extend service life in demanding environments.

• Base metal: tin bronze — improved conductivity and strength.
• Surface finish: nickel plating — resists corrosion and abrasion.
• Result: stable electrical performance across repeated mate cycles.
• Suitable for environments where occasional exposure or handling occurs.

Who is this for: JRready ST6295 size 20 solid pin contacts are intended for technicians, harness builders, and engineers who assemble or repair DTM-style connectors and need a reliable, corrosion-resistant crimp pin for 16–22 AWG solid conductors. If you require consistent current capacity up to 7.5 A, durable mating cycles, and professional-grade crimp performance, this 50-pair kit is a practical choice for workshop, field-service, or small-batch production work.
