Insulated Ring Lugs | 1.5mm – 4mm
Blog Article
Here’s a detailed breakdown of insulated ring lugs (or ring terminals) in the 1.5mm² – 4mm² range, including specifications, standards, and crimping recommendations:
Insulated Ring Terminals (1.5mm² – 4mm²) – Key Features
Material:
Conductor: Tin-plated copper for corrosion resistance.
Insulation: Color-coded PVC or nylon sleeve (provides strain relief and electrical insulation).
Hole Sizes: Typically M3, M4, M5, or M6 (for screw/stud connections).
Standards: Compliant with DIN 46234, UL, or IEC.
Color Coding & Size Chart (1.5mm² – 4mm²)
| Wire Size (mm²) | Insulation Color | AWG Equivalent | Common Hole Size |
|---|---|---|---|
| 1.5 mm² | Blue | 16–14 AWG | M3, M4 |
| 2.5 mm² | Blue/Yellow | 14–12 AWG | M4, M5 |
| 4.0 mm² | Gray/Yellow | 12–10 AWG | M4, M5, M6 |
Types of Insulated Ring Terminals
Standard Insulated – Basic PVC insulation.
Heat-Shrink Insulated – Provides a tighter seal (better for harsh environments).
Flanged/Non-Flanged – Flanged design prevents over-insertion into terminals.
Recommended Crimping Tools
For 1.5–4mm²:
Hand Crimpers (e.g., Weidmüller PZ 6 R, Phoenix Contact ATC 1.5-4).
Ratchet Crimpers (e.g., Klein Tools 1005, Ideal 30-429).
Die Compatibility: Use hexagonal or indent crimp dies for secure connections.
Common Applications
Automotive wiring (battery terminals, grounding).
Control panels (terminal blocks, relays).
Industrial machinery (power distribution).
Top Brands to Consider
Phoenix Contact (high reliability).
TE Connectivity (wide range of options).
Weidmüller (industrial-grade).
3M (heat-shrink variants).https://store.unigulfsupply.com/product/insulated-ring-lug/
