Even with a very high-quality sensor, defects can infiltrate. Causes of failure and sources of error usually begin with the connection of the sensor. Adapted cables and plugs are rarely considered, which can lead to mechanical failures after a relatively short period of continuous operation.
Damage to the cable insulation, broken plugs and broken cables are the consequences.
How to choose the right cable?
First of all, the mechanical load capacity should be determined. The prevailing tensile forces are as relevant as the question of whether the installation should be fixed or flexible. Furthermore, the ambient temperature should be known. Depending on the humidity, cables require longitudinal and transverse water resistance.
Special operating conditions also have a major influence on the selection of the cable, whether it is EMC, high vibrations, shocks, or the surrounding acids and alkalis.
How to choose the right connector?
The suitability of the cable for the operating conditions is determined by the respective degree of protection. An IP protection class protects against the ingress of foreign objects and water, in the plugged and unplugged state. The IK degree of protection is selected according to the intensity of the mechanical force.
It would also be important to know how many mating cycles the connector must allow.
Precautions must also be taken with the connectors with regard to special operating conditions, such as EMC, shock and vibration. Furthermore, attention should be paid to resistance to acids and alkalis., as well as extended temperature ranges.
