Delock DL4 Solar Connector – Plug-to-Socket Pair for Crimped Solar Cables
The Delock DL4 Solar connector is a plug-to-socket pair designed for crimping onto solar cables. It provides a secure, weather-resistant connection point in photovoltaic systems, ensuring reliable power transmission between solar modules and installation components.
Plug-to-socket design enables quick, tool-free connection and disconnection of solar cables
Black housing withstands UV exposure and outdoor environmental conditions
Set of 2 pieces — one plug and one socket — sufficient for a single cable joint
Compact, lightweight design (27 g total) fits into tight junction boxes and enclosures
What Sets the Delock DL4 Apart
Unlike multi-piece connector systems that require separate sealing elements, the DL4 integrates the contact and housing into a single compact unit. The crimp-on design eliminates the need for soldering, reducing installation time and eliminating solder-related failure points in outdoor solar installations.
Ideal For
Photovoltaic system installers and maintenance technicians working on residential or commercial solar arrays. The DL4 is suited for connecting MC4-compatible solar cables on rooftops, ground-mounted systems, and solar carports where a clean, secure, and weatherproof joint is required.
Application of the Delock DL4 Solar Connector
Strip the solar cable end to expose the conductor
Insert the conductor into the crimp contact
