X-CONTACT: It's what's inside that counts …


As a specialist for industrial plugs and sockets, MENNEKES presents with X-CONTACT a completely new contact sleeve solution. Innovative, simple, durable and safe.

Industrial connectors and receptacles of 63 A and 125 A are often exposed to the toughest conditions. On construction sites, in mines and tunnels or in heavy industry, they have to operate reliably while often covered in dirt and surface water.  

Conventional connectors and receptacles of this category have always been a compromise between ease of handling and contact quality. Easy handling was only possible where contact quality was compromised, and vice versa. Due to the physical conditions, this dilemma seemed to be inevitable.

With X-CONTACT, Mennekes launches a new system, which combines a totally reliable electrical connection with the ultimate in ease of handling.

More Contact…

For connectors and receptacles the contact sleeves are essential for the quality of the contact closure.  It is important to achieve the best possible balance between a safe contact closure and ease of insertion. We have successfully implemented this with X-CONTACT in an entirely new way.

Due to a completely new manufacturing process, the X-CONTACT sleeve obtains resilient properties based solely on its material characteristics without the need to use any additional spring elements. Thanks to the shape of the X-CONTACT sleeve, a particularly safe contact closure can be achieved.

… less effort!

The special design of the X-CONTACT reduces the effort of insertion and withdrawal. An advantage that simplifies work processes and improves safety especially with high electrical currents. With X-CONTACT, MENNEKES creates a safe contact closure and easy handling at a new, equally high level.

But how does X-CONTACT achieve these benefits even with currents of 63 A or 125 A?  Essentially with the special pretreated material, an innovative work process and of course
a new shape.

A glance into the opening of an X-CONTACT sleeve reveals the intelligent functional principle: the X-shaped slot and groove in the inner wall provides four advantages

of the new design: innovative, simple, durable and safe. The X principle.

Reliable even under the toughest conditions

Innovative, simple, durable and safe – the X principle is not a promise, it’s a fact. But it is even better because X-CONTACT sleeves withstand the toughest conditions due to their simple, brilliant functional principle. The interaction of the resilient material and groove is not only the guarantee for a secure contact closure, it also has the practical side affect that any contamination is removed when connecting and disconnecting the plug. Even surface corrosion is removed by the spring effect of the X-CONTACT sleeves.

For particularly corrosive environments – such as irritant chemical substances like ammonia – we offer the nickel-plated contact sleeves with all their known advantages.


With X-CONTACT Mennekes sets the standard for all industrial connectors and receptacles. Mennekes will incorporate this new technological design in their entire product range. In future, all MENNEKES connectors and receptacles for currents of 63 A and 125 A will have X-CONTACT, this means that you will benefit from the advantages of the X-CONTACT in all applications.
