The strong magnetic fields generated by industrial spot welders cause unprotected sensors to malfunction or fail. To prevent misalignment during assembly, a valve manufacturer requires inductive proximity sensors that withstand the exceptionally high currents needed to weld aluminum parts. Contrinex S600 Weld-Immune inductive sensors are immune to electromagnetic interference and sense targets in steel and aluminum equally effectively. Highly reliable and robust, they provide a cost-effective solution with a best-in-class service life.
Customer benefits
- Rugged inductive sensors ensure accurate positioning of aluminum components, eliminating assembly rejects and minimizing downtime
- Weld-Immune sensors provide immunity to electromagnetic interference from 50Hz and medium-frequency weld fields
- Exceptionally high currents needed for welding aluminum do not inhibit accurate detection of targets
- Factor 1 sensors require no reduction in sensing distance for aluminum targets, reducing the chance of accidental collisions
- Proven technology ensures reliable operation with extended service life and minimal down-time
- Optional addition of high-performance ACTIVSTONE® ceramic coating prevents spatter accumulation and inhibits sensor-performance degradation
