A photovoltaic system is only as good as its smallest components. Starting with its connectors. The connectors need to be able to withstand the effects of wind and weather, as well as any temperature fluctuations. And they need to do this for up to 25 years. They also need to be economical and easy to use.
The WM4 C is a classic plug-in connector for crimp connections that meets the high requirements of the DIN EN 50521 standard. In addition to its high load-bearing capacity, it also stands out thanks to its compatibility with the entire range of plugs.
Suitable for use either as a housing or a field plug-in connector: the WM4 C is very versatile and is perfectly suited for use in automated production. Its innovative anti-twisting protection makes it even more convenient for assembly in housings.
In addition to meeting the highest standards, a plug-in connector should also be easy to handle. Thanks to its high level of quality and good installation properties, the WM4 C successfully meets all of the latest practical requirements.
