Inductive sensors are considered virtually failure-proof components, yet they still regularly “burn out” and bring production lines to a standstill.

Based on an analysis of 100 real-world cases from maintenance departments, we present the 12 most common causes of failure – from mechanical impacts and water ingress, through EMC interference and vibrations, to errors in sensor selection and installation.

The Most Common Causes of Inductive Sensor Failures

In the article, you will find practical information on issues such as:

• mechanical damage and impacts,
• water ingress and moisture,
• EMC interference,
• vibrations,
• incorrect sensor selection,
• improper installation.

Practical Diagnostics and Preventing Downtime

We also discuss practical diagnostic methods and provide checklists to help identify the source of a problem more quickly, reduce the risk of recurring failures, and minimise unplanned production downtime.

Inductive Proximity Sensors: From Detection Physics to Advanced Diagnostics Discover the technical intricacies of how inductive sensors operate. We explain how they function, why the choice between PNP and NPN is critical for machine safety, and how to eliminate EMC interference. Read our comprehensive guide and minimize downtime in your facility using proven preventive methods.
