1 Dual-action prole seal provides absolute impermeability.
2 Reaching a torque of 0.6 Nm activates the mechanical vibration protection.
This dual-acting interlock oers high shock and vibration resistance up to
50 G.
3 Integrated xed stop prevents the plug connector from being screwed too
tight.
4 High-quality material: Long service life and corrosion resistance veried by
Ecolab certication.

Shielding
The devices must be made such that:
1. The generation of electromagnetic interference is limited
to a level where it is possible to operate the devices as
intended;
2. The devices have adequate resistance to electromagnet-
ic interference so that it is possible to operate them as
intended. With round connectors it is important to ensure
that the braided shield of the cable is attached carefully to
the shield connection of the plug connector. A wraparound
attachment (360°) is best in this regard. However, good
shielding values, often adequate in practice, can also be
achieved by connecting the braided shield rmly to the con-
ductive housing. Plug connectors made only of plastic with
no metal sleeves cannot be used for this as the braided
shield cannot be attached to them.
It is also important that when the connector is being plugged
in that perfect contact is made with the mating connector, and
that the mating connector also has a good contact with the
device chassis.
Silicone free
In some areas, such as paint shops, silicones must be avoid-
ed. This is because silicones have low surface energy which
can cause surface defects in paint lms and adhesive layers,
which are known as craters. It can even cause areas of glue
to peel o. To avoid these paint wetting impairments SICK
provides silicone free cables.

Suitability for drag chains
A drag chain (also known as an energy chain) is a device used
in mechanical engineering and construction which guides and
protects exible cables and pneumatic or hydraulic hoses.
Drag chain cables are connected to machine parts exposed
to repetitive movements, e.g., in machine tools, lathes, and
high-bay warehouses, and they supply the connected machine
parts with power and information. Drag chain cables must
meet widely diering mechanical requirements depending on
the application in dierent industry sectors, e.g., in terms of
exibility, bending and torsional properties, number of bend
cycles, bend cycle frequency, travel speed, service life, wear
resistance, and bend radius. If cables meet these require-
ments they are said to be suitable for drag chains.
