4 Pin Industrial Connector

Designed for real-world industrial abuse, our Third Generation High‑end Industrial Connectors provide stable connections for power and control circuits in environments where reliability matters most. Choose from heavy‑duty 4‑pin options covering the voltage ranges commonly specified in factories and job sites—110–130V, 220–240V, and 380–415V—along with a variety of current ratings and pole configurations. With IP44 and IP67 protection levels available, these connectors are suited for dusty workshops, damp areas, and outdoor installations. A reinforced housing and well‑engineered earth contact help deliver secure engagement, reduced vibration-related loosening, and long service life. Select the 4 Pin Industrial Connector that matches your system requirements.
