The Applications

1. Wear Detection on Conveyor Belt Clamps

In conveyor systems used for bulk materials or logistics handling, metal belt clamps face continuous movement and wear. The IQ40-40NNSKK0S can be mounted near these moving sections to detect the metal clamps passing by with precision. Its 40 mm sensing range and non-flush design enable reliable operation even with vibration or misalignment. The IP69K protection ensures durability against dust, moisture, and cleaning processes, allowing early wear detection before mechanical failure occurs — minimizing costly production stoppages.

2. Rack Positioning in Automotive Production Lines

In vehicle assembly areas, heavy metal racks carry body parts through welding and coating zones. The IQ40-40NNSKK0S provides accurate positioning feedback for these racks, even when surfaces are oily or coated with paint mist. Its robust rectangular housing withstands shocks and heat, while the non-contact inductive sensing maintains precision through thousands of cycles. This guarantees reliable rack identification and smoother transitions between automated stations, reducing manual checks and preventing collisions.

3. Metal Part Presence Detection in Fast Assembly Lines

During automated component assembly, every part must be precisely located to prevent downstream errors. The IQ40-40NNSKK0S excels here with fast 100 Hz switching and high repeatability, detecting even small metallic parts without physical contact. Its wide temperature tolerance and mechanical resistance make it ideal for vibrating assembly stations. This ensures continuous quality control, accurate part feeding, and reduced maintenance interruptions in mass-production lines.

4. End-Position Monitoring for Machine Tools and Cylinders

Machine tools and hydraulic systems require dependable feedback to confirm when a moving element reaches its end position. The IQ40-40NNSKK0S delivers precise detection with its extended 40 mm range, accommodating mounting variations and part wear. Its sealed PA 66 housing resists coolant splash, oil, and metal chips. This stability under harsh workshop conditions prevents false readings, enhances safety, and ensures smoother automation control during machining or assembly operations.
