Non-interchangeable security on flexible media interfaces

The requirements for flexible media interfaces are varied and go far beyond a fast connection of mobile components with stationary systems. In many production processes, it is important to avoid an incorrect fluidic media line coupling already during the design phase of system planning. The basic idea is the Poka yoke principle which means eliminating incorrect actions through appropriate precautions:

Process reliability and thus protection against mix-ups is a sensitive issue of increasing importance especially when dealing with aggressive and hazardous substances like those used in the chemical and pharmaceutical industries. As a technology leader in the area of industrial quick coupling systems, WALTHER-PRÄZISION addressed this challenging issue early on and developed a series of pioneering locking and signal elements designed to connect media interfaces safely, flexibly and without any mix-ups. In this way, optical, mechanical, electronic and a combination of these construction elements are used today.

Mechanical locking elements
With monocouplings, for example, various ring diameters can ensure designs on the guide parts of the locking coupling or mechanical coding so that only coupling halves which belong to each other can be be connected to each other with the corresponding closure. Differently coloured guide parts continue to facilitate the optical classification.

Classic shapes for non-interchangeable monocouplings are triangular, square or pentagonal heads. The distinctive forms of closure make an optical classification easily possible.

Multicouplings – built-in non-interchangeable security
Multicoupling systems by WALTHER PRÄZISION are non-interchangeably designed. A variety of liquid, electrical or gas lines can be process-reliably and non-interchangeably connected at the same time with customised systems for multichannel media interfaces.

Depending on customer requirements, the multicouplings are equipped with additional signal elements. The use of these sensors allows monitoring of individual coupling conditions. This enables the integration of the multicoupling into an automatically controlled process.

Customised high-tech solutions
With the remote monitoring of processes, electronic safety and signal elements play a decisive role in the constant monitoring of the status of a separable connection. Especially in complex production plants, the apparent condition check is often dangerous or even impossible.
