SICK now offers connection cables for almost all inductive, magnetic and optoelectronic sensors to meet greater demands.

The polyurethane-coated sensor cables are free of halogens and silicon, withstand cooling and lubricants, are suitable for drag chains and are resistant to torsion.

As a result they are suitable for harsh operating conditions, such as those found in automobile construction, on machine tools and processing machines, or on robots.

M8 and M12 device plugs with varying numbers of pins, straight or angled cable inlets, and differing cable lengths, meet almost all installation conditions.

In many locations major demands are placed not just on sensors, but also on the connection technology.

Fire protection regulations require there be no halogens; coating processes in automobile construction require absolute freedom from silicone; drilling oils and other lubricants attack conventional PVC cables; conveyor, handling and robotic systems require cables that are both flexible and resistant to torsion.

In addition to the usual orange-coloured PVC cables Sick now offers suitable black, and thus colour neutral, control cables (proven in exhaustive trials) for inductive, magnetic and optoelectronic sensors that are used in such environments.

Thus, among other things, cooling and lubrication resistance were tested by three-week storage in a test bath heated to 70°C. Drag chain trials resulted in high acceleration and speed values as well as bending radii of only 10 x D in addition to more than 2 million guaranteed bending cycles.

Sick maintains a comprehensive range of connection technology for raised demands. M8 connection plugs are available with 3 or 4 pins, and M12 connection plugs with 4or 5 pins. For each variant there is a choice of straight or angled cable inlets.

Differing cable lengths cover all distances between the sensor and the control system. The PUR cables are UL/CSA-approved and can thus be used all over the world.
