Stäubli touts crimp-free MC4 connector

Stäubli launches a new crimp-free cable coupler

With the MC4-Evo ready Stäubli launches a new crimp-free cable coupler within its Original MC4 product portfolio. The MC4-Evo ready is an easy-to-use and quickly-to-assemble PV connector for solar installations up to 1500 V DC.

The assembly of this new connector is crimp-free based on Stäubli’s snap-in-technology. This feature eases and speeds up assembly and installation time while still offering safe and reliable operation for in-string and homerun applications. The new MC4-Evo ready is mateable with the existing connectors of the Original MC4 product portfolio.

Crimp-free connectors do not require special tools as the contact is made by an automatically closing spring clamp. The connectors come pre-assembled and are eady to use. Simply insert the stripped PV cable, listen to the click, screw on the cap nut and you’re ready to connect.
