For reliable plug connections – even after many plug cycles

The benefits of our plug connections are clear: they create detachable connections between a cable and a device, for example, and withstand hundreds of plug cycles. EPIC® industrial plug connections are used for power supply as well as signal and data transmission in various industrial environments and support the cable in its tasks: they supply another piece of equipment with power, control the signal transmission and guarantee data exchange. We offer a variety of plug connection variants for a wide range of applications and with different ordering options. Receive individual parts, kits or customised assemblies.

What are the plug connections used for?

While electrical connections were previously fixed, soldered installations often subsequently left for long periods, this task is now adopted by plug connections that can be disconnected and reconnected again thousands of times, always creating reliable contact. A plug connection is therefore the elementary component of a detachable, secure plug connection between two cables or for connecting a cable to a device or machine.

Which plug connectors are available at LAPP?

Overview of possible plug connections with connectors

Not all plug connectors are made equal. The shape defines the function. Below you will find an overview of our plug connector range; from there, you can navigate much more easily to the product of your choice.

Find out on the respective sub-pages how industrial plug connectors are structured, which connection technologies are suitable for assembly, which areas of application result from the respective product group and much more.

Rectangular connectors

Suitable for industrial applications in mechanical and plant engineering, control cabinet construction, lighting and sound technology, etc. as they are robust in harsh environments and easy to use. They are largely used to supply power and transmit signals. However, the modular rectangular connector systems EPIC® MC modules and EPIC® MH enable flexible mixed assembly and are therefore also used for data transmission.

Housings and inserts: There are robust, versatile and highly corrosion-protected housing series available. With the inserts, you can choose between fixed pole or modular, and thus absolutely customised inserts.

Circular connectors

These are particularly suitable for special applications in measurement, control and regulation technology, servo drive technology, conveyor technology or industrial robots.

In this product group, you will find power connectors and signal connectors in the sizes M12 to M58, as well as single-pole EPIC® POWERLOCK connectors for use with mobile and stationary energy or emergency power generators or battery storage systems.

Solar connectors

Suitable for direct current applications within photovoltaic systems, i.e. for cabling solar modules, inverters and stand-alone systems. The plug connectors can be freely assembled.

Data connectors

Suitable for data transmission with copper-based electrical data cables (fieldbus, sensor-actuator, Ethernet) as well as optically transmitting fibre optic cables. In this product group, you will find the most common plug connectors for harsh industrial environments, structured building cabling, and use in data centres or control cabinets.

An industrial connector is, so to speak, the icing on the cake at the end of a cable that supplies another piece of equipment with energy, controls it, reads signals or transmits data from a transmitter to a receiver. 

Plug connectors can be found in all industrial environments: in mechanical and plant engineering, in control cabinets and of course in outdoor applications. The different shapes, sizes and variants enable a wide range of applications. 

Whether you want to connect the field level to the control cabinet, the control unit or machine-to-machine communication, you are sure to find the right product at LAPP, including all the necessary comprehensive information.

The trend towards miniaturisation and performance compression is not only evident in the cable area, but is also reflected in the plug connectors. Ideally, new connectors should be all-rounders, take up less space in the application, be PROFINET-compliant and vibration-resistant, and have comprehensive shielding for maximum electromagnetic compatibility.

At LAPP, we do everything we can to tackle new challenges with you as a customer and to develop the perfect plug connector for your respective operation site.

Smallest power connector available on the market- EPIC® POWER M12L

Two that fit together like a pot and a lid: cables and plug connectors

Cables and plug connectors are simply in perfect symbiosis. This is what Oskar Lapp (1921-1987) thought when he founded the LAPP family company in 1959 and brought the first industrially produced ÖLFLEX® power and control cables with coloured cores to the market. Shortly afterwards, the first rectangular connectors from the EPIC® product brand appeared and rounded off the portfolio.

EPIC has always stood for "Environmentally Protected Industrial Connectors".

Our EPIC® products also meet your individual requirements:

For voltages up to 1.5kV

For currents up to 660A

With 1 to 280 contacts

EPIC® industrial connectors- We connect innovations

From loose to assembled – you have the choice!

Kits and sets for minimised ordering effort

Don't feel comfortable researching and then purchasing all the individual components required for manufacturing a plug connector? Do you therefore want to reduce your ordering effort and eliminate the risk of incorrect orders? 

Understandable – you're not alone in this! Many customers prefer assembled plug connector sets with optimally coordinated components. 

That is why you will find our kits for rectangular, circular and solar connectors in each plug connector product group, consisting of a housing, insert, contacts and conduit gland, for example.

The worry-free ÖLFLEX® CONNECT package

If you like keeping things really convenient, effective connection technology also means we can produce plug & play solutions for you. Suitable for immediate use and perfectly assembled. Either with products from the standard range or customised. Get to your desired cable including a moulded plug connector in just a few steps!

Plug connector term definitions

In recent years, the wrong individuals have become involved in technical language relating to plug connectors. Things that are usually still easily understood in casual language and oral communication can often lead to misunderstandings in written communication. We're tidying up incorrect designations! 

When used correctly, the commonly used term plug actually only describes the male variant, but not the whole plug connector. A plug connection consists of a male part, known as the plug, and a female part, known as the socket.

In the interior of the plug connector, a distinction is made between the pin and the socket.
