Pre-Insulated Crimp Terminals
Pre-insulated crimp terminals are supplied in three standard wire-size formats and in the red, blue, and yellow colour scheme. While PVC insulation is typical, insulation materials such as nylon, polycarbonate, and Kynar are also available. We offer wire size compatibility from 0.2 mm² up to 150 mm² to suit a wide range of applications.
1. Standard Colours & Materials
The standard materials and colour coding help with rapid identification and specification matching:
- PVC insulated terminals (typical insulation material) in red, blue, yellow
- Alternative insulation materials offered including nylon, polycarbonate, Kynar
- Colour coding correlates with wire gauge ranges (small, medium, large)
2. Size & Wire Gauge Range
These terminals are designed to fit a wide range of wire sizes to meet various current and insulation needs:
- From very small wire sizes (0.2 mm²) up to heavy-gauge terminals (150 mm²)
- Wire-terminal compatibility depends on material (copper, etc.), insulation thickness, and crimping tooling
3. Choosing Insulation Type
The insulation material affects durability, environmental resistance, and mechanical properties:
- PVC – standard budget-friendly insulation, suitable for many non-extreme conditions
- Nylon – improved mechanical strength, better resistance to abrasion and temperature
- Polycarbonate – robust, impact-resistant, wider temperature range
- Kynar – high-performance polymer with excellent chemical resistance
4. Applications & Considerations
When selecting pre-insulated crimp terminals, consider the following factors:
- Operating temperature and environmental exposure (humidity, chemicals, UV)
- Current capacity relative to wire gauge and cross-section
- Mechanical stresses and vibration at installation point
- Compatibility of insulation with conductor type (e.g. copper)
- Crimp tool type and calibration to ensure a secure connection
