The models of copper wire terminals in the peephole series

1. Model Naming Convention (Example)

PEEK-CU-XXX-XX

●PEEK: Series code (indicating “peek-through” series).
●CU: Material identifier (copper).
●XXX: Core parameter code (e.g., current rating, wire gauge range).
●XX: Additional features (e.g., protection class IP, color, locking mechanism).

3. Key Selection Factors

1. Current and Voltage Ratings

●Low current (<10A): For sensors, relays, and small power devices (e.g., PEEK-CU-Mini-1.5).
●Medium-high current (10–60A): For motors, power modules, and heavy loads (e.g., PEEK-CU-35-6.0).
●High-voltage applications: Custom models with withstand voltage ≥1000V.

2. Wire Gauge Compatibility

●Match wire gauge to terminal specifications (e.g., 2.5mm² cables for PEEK-CU-10-2.5).
●Use compact models (e.g., Mini series) for fine wires (<1mm²).

3. Protection Class (IP Rating)

●IP44: Dust and water resistance for indoor/outdoor enclosures (e.g., distribution boxes).
●IP67: Fully sealed for extreme environments (e.g., industrial robots, outdoor chargers).
●IP20: Basic protection for dry, clean indoor use only.

4. Functional Extension

●Locking mechanism: Prevent accidental disconnection (e.g., suffix -L).
●Color coding: Differentiate signal paths (red/blue/green indicators).
●Rotatable design: Flexible cable routing angles.

5. Selection Summary

1.Define Load Requirements: Match current, voltage, and wire gauge first.
2.Environmental Adaptability: Choose IP67 for harsh conditions (outdoors/wet), IP44 for general use.
3.Functional Needs: Add locking mechanisms or color coding for safety/circuit differentiation.
4.Cost-Benefit Balance: Standard models for common applications; customize for niche needs (miniature, high-voltage).
