The modular interface

The fully modular design principle of this multiple connector makes it possible to combine such different operating media as compressed air, vacuum, gases, coolants, liquids, as well as electrical and electronic signals in a single interface. MULTILINE ADAPTIVE + E is an individually configurable multiple connector that is available with or without shut-off, a drip-free version and also inserts for electrical and electronic signals.

Modular kit system for multiple and multi-media connectors

The optimally compatible adaptive inserts of the MULTILINE ADAPTIVE + E allow flexible integration of different diameters, connection types and media in one modular multiple connector.

MULTILINE ADAPTIVE + E is a significant improvement over previous multiple connectors: After selecting a base body with the required number of connections consisting of a plug and socket, the adaptive inserts allow the user to combine exactly those connections that are needed for a particular application. If the requirements change, the connector can easily be adapted by hand, without the use of tools.

A multiple connector for compressed air, gases, liquids, electrical and electronic signals

The E-connector line offers the widely used and standardised M12 connectors in different constructions for diverse applications. They include different codings and two versions of the M12 power plug for power electronics up to 600 volts. When combining the M12 power plug with connectors for liquids we recommend drip-free adaptive inserts and the locking lever.

The modular multiple connector provides the first complete multi-media interface that also allows fast and easy adaptation. The adaptive inserts can be configured as needed, regardless of tube size and material. Various materials (stainless steel, brass), different diameters, and different shut-off functions and seals make this modular multiple connector a genuine modular kit system.

In addition to combined concepts for different control lines, it is also possible to create complete solutions for electrical and electronic connections.

The MULTILINE with union nut

Thanks to the modular kit system, our versatile multi coupling adapts to any application and is available with both a locking lever and a union nut
