Cable installation guidelines

Please follow recommended cable installation practices for industrial applications. Described below are both appropriate and inappropriate installation practices for sensor/actuator cordsets. By following these recommendations, you will guarantee long service life and reduce maintenance costs.

Bending radius

Installation of sensor/actuator cabling: bending radius  

Cable installation guidelines: bending radius

Ensure a sufficient bending radius. This is important because a greater bending radius will better absorb energy that results from cable movement.

In fixed installations, the minimum bending radius is generally 5 times the diameter.  For flexing/moving installations a minimum of 10 times the diameter is recommended.

Strain relief

Installation of sensor/actuator cabling: loads  

Cable installation guidelines: strain relief

A sufficient cable loop at the connection point can prevent the cable jacket and inner conductors from stress and premature wear. 

In applications with stress loops, sufficient clearance is needed for additional energy to be absorbed.

Moving and continuously flexed installations

Installation of sensor/actuator cabling: cable length  

Cable installation guidelines: moving and continuosly flexed installations

In the case of linear or torsional flexing installations, the cable length should be sufficient to provide adequate slack for absorbing tensile stress.

This can be achieved using mechanical supports and cable loops

Cable track installation

Installation of sensor/actuator cabling: cables in power track chains  

Cable installation guidelines: cable track installations

Cables should be laid individually and loosely next to each other within drag chains. Those cables with very different diameters should be isolated with bridges. If bridges cannot be used, we recommend our cables with an outside diameter <10 mm should be laid loose within a guide tube in the cable track. 

Arrange heavy cables on the outer side of the track and light weight cables, such as our sensor cordsets, laid inwards. They should have adequate strain relief at both ends. A distance of 20 to 30 times the outside diameter of the cable is recommended between the connection point and where the bending motion ends. 

Important: when laying the cables, observe the information provided by the drag chain manufacturer.

Cable bundling

Installation of sensor/actuator cabling: cable bundling  

Cable installation guidelines: cable bundling

When bundling cables together, always ensure that they can move freely within the bundle. 

If the bundle is too tight the cables could be pinched and stressed.
