Common Questions About MC4 Connector Crimping
Crimp with Confidence
We carry the complete range of MC4 solar
MC4 connectors typically come in male and female pairs, with the male connector having a protruding pin and the female connector having a recessed socket. Both male and female connectors are made from multiple components that work together to form a weather-resistant electrical connection, such as:
Housing
A durable plastic shell that protects the metal contact. It is typically made from UV-resistant and flame-retardant materials such as PPO (Polyphenylene Oxide) or PA (Polyamide).
Crimp Pin (Metal Contact)
Made of conductive elements and will be crimped onto the stripped wire. It ensures power transfer between connective cables.
Seal Rings and Gland Nut
These components work together to create a waterproof and dustproof seal around the cable. The rubber seal ring fits around the cable entry point, pressing against both the cable and the housing. The gland nut tightens down on the seal, further compressing it and securing the cable.
Locking Clips
Typically made from stainless steel and designed to engage in a snap-lock mechanism, creating a connection resistant to vibration, mechanical tension, or accidental pulls. They secure the male and female connectors together to prevent unintentional disconnection, ensuring a reliable electrical connection.
