Photovoltaic Solar Panel Connectors – Dependable PV Connectivity from elmex

With the drive for greener energy the utilisation of solar power is a popular choice, from the large-scale solar farms you can see dotted around the countryside to small scale solar panel installations fitted to the roof of a house. All these systems require a reliable and secure method of connector technology to ensure the power they create is safely transferred to where it should be.

Where reliability and compatibility matters elmex Photovoltaic (PV) Connectors are a dependable solution, offering a large array of designs to suit a wide variety of applications. Here, we take a quick look at just a small selection of some of the solar panel connectivity solutions manufactured by elmex and available to purchase from Kempston Controls today.

Photovoltaic Connectors

Photovoltaic Straight Connectors

The elmex PV (Photovoltaic) Solar Straight Connectors, with NEC interlock, have been designed for applications in PV power generation systems, featuring a male plug and female socket design and are constructed from a UV resistant flame retardant thermoplastic. These solar panel connectors incorporate a flexible water-tight sealing (providing IP68 protection) and come in male and female connector versions to minimise the chance of incorrect connections.

These hardwearing PV straight connectors are certified for PV solar cables 2.5, 4.0, 6.0 mm² diameter. The cables used should be TUV certified as per standard 2Pfg 1169/EN 50618 to ensure a proper connection.

ATEX Rated Industrial Power Socket and Plugs from Pepperl + Fuchs

There are an untold number of industrial manufacturing industries in existence today, from the manufacture of ceramics, automotive components and the processing of flour, to chemical and fuel production to name just a few. Within all of the industries, some will take place in a relatively safe environment where the chance of a dangerous explosive atmosphere occurring due to build-up of volatile chemicals or particulates in the air is next to nothing, to precisely the opposite.

In the later situation, it stands to reason that you will need to ensure that the machinery, devices and the means to provide them with power, are as safe as possible these areas will ideally be ATEX rated(1) to various degrees. You can never be too safe when it comes to operating machinery in an environment that demands intrinsic safety for obvious reasons. To that end and for a power connectivity solution you can rely on, you need look no further than Pepperl + Fuchs to help you make that safe connection in dangerous environmental atmospheric situations.
