Marking systems
It is important to mark cables, connectors and devices
so that there is unambiguous, logically arranged and
permanently legible identification. This helps to prevent
mis-wiring, increases safety and reduces work levels, which
in turn reduces manufacturing and maintenance costs
including those caused by production down-times. Our line
of marking products offers a practical solution for labelling
all types of equipment.
Housings
A wide variety of housings are available in different sizes
and materials (polystyrene, polycarbonate, polyester,
ABS and aluminium); these offer solutions for protecting
electronic circuits and for installing devices or terminal rails.
The application’s requirements determine which material
should be used for the housing.
Our line of accessories are well designed to fit with our
users’ requirements. Our accessories allow you to move
forward on a great number of technical applications with a
minimum of effort and parts. An overview of the portfolio:
• Cabling ducts
• Wire-end ferrules
• Cable gland systems
• Insulated connectors
• DIN rails

Tools
There is also a wide range of tools available for the efficient
processing of conductors, wires and cables. Our product
line includes diagonal cutters, stripping tools, one-hand
cable cutters, crimping tools, screwdrivers, as wells as
punching and cutting tools for mounting rails and profiles.
