Plug into modularity

21 June 2013

In modern production the clear trend toward modular systems and customised production necessitates short setup times, says Thomas Maier of Eisele Pneumatics

Systems are becoming ever more complex and confusing, which makes retrofitting and troubleshooting more difficult, so well-organised pneumatic power supply lines in a production facility are increasingly important. To connect every hose and every line as a single element is not only a nuisance, but also costs money. The more often connections have to be uncoupled and recoupled, the greater the savings that can be achieved using multiple connectors.

Bundling of four, six, eight, ten or twelve hoses in one plug-in connection facilitates simple installation. That is why Eisele developed MultiLine multiple connectors for applications with a large number of plug-type connections. The line consists of connectors for air ducts, fluids and a multiple connector that combines both types of lines in one connection.

The MultiLine 1811 series features one- or two-sided shut-off valves, enabling coupling and uncoupling with little physical effort, also under pressure. To guarantee a secure threaded connection, the connector is optimised to establish a leak-free connection even before the connecting union nut is tightened. The union nut has an end position that eliminates leaks due to incorrect installation.

More combinations

With the 1870/1871 series it is now possible to combine compressed air and electric lines in one connector. To ensure the required flexibility in production, pneumatic actuating energy is increasingly being supported by servo systems. Electronics help pneumatic actuators to remain competitive with respect to positioning accuracy and control in comparison with purely electric actuators. To include this connection in the media supply therefore seems obvious.

With the new MultiLine 1870 and 1871 multiple connectors Eisele has succeeded in developing an innovation that opens up new possibilities for connection solutions: Until now there was no way to combine electrical wiring and compressed air lines in one connector. However, reacting to customer requests, Eisele  has developed a solution that makes it possible to connect up to eight hoses and three to 26 electrical wires.

In addition to the new application possibilities, the light weight, compact design enables high power density and facilitates ease of installation. The Eisele multiple connector can be coupled and uncoupled under pressure and voltage. The design of the pneumatic shut-off valves is optimised so that only minimal pressure has to be overcome to establish the connection.

The purely pneumatic connectors of the 1811 series are also equipped with shut-off valves, so that they can be coupled and uncoupled under pressure. The customer decides whether the shut-off valve should be mounted on the plug side or the socket side. Shut-off on both sides is also available as an option.

Modularity

Highly flexible, the new connector enables the connection of different sized hoses in one unit via removable sleeves. This makes it easier for the user to establish or change connections as needed. The connector also allows reductions from large to smaller hose diameters. Mix-ups can easily be avoided by colour and geometrical coding of the connections.

Connection of the plug and socket is intuitive and, if necessary, is also possible without visual contact. The connection is secured by a union nut, which also ensures loss-free coupling and uncoupling under pressure. If the full number of hoses is not needed, the plug positions can be securely sealed with blind plugs from the extensive line of accessories. The quality of the single components is what makes this new dimension of connection technology possible and allows mounting in the switch cabinet or decentral installation.

Key Points

  • Bundling of four, six, eight, ten or twelve hoses in one plug-in connection facilitates simple installation
  • With the 1870/1871 series it is now possible to combine compressed air and electric lines in one connector
  • The new connector enables the connection of different sized hoses in one unit via removable sleeves
