Proximity sensors from Omron

Sensors detect iron and aluminum

Manufacturers in the automotive industry are striving to meet the demand for electric vehicles and reduce fuel consumption through lighter vehicles by favoring aluminum over iron. As the prevalence of mixed production lines containing both metals increases, so does the demand for proximity sensors with a suitable switching distance.

The new E2EW series from Omron has been developed to meet these requirements. According to the manufacturer, the proximity sensors currently offer the widest switching distance in their category and have been optimized to withstand the harsh conditions of typical automotive welding processes with a fluoroplastic coating that offers increased spray resistance.

The switching distance of the E2EW series is about twice as far as previous models for ferrous metals and six times as far as previous models for aluminum. They therefore offer a solution for mixed metal production lines. Due to the identical switching distances for both metals, the sensors support a common design for position detection. They also reduce unexpected system failures by minimizing detection errors with unstable objects.

In addition, the E2EW sensors have a lifetime 60 times longer than previous models in typical automotive welding applications. Support for IO-Link enables real-time collection of detection level and temperature change data from proximity sensors from a single location. as
