OMRON Corporation has launched the E2EW Series Full Metal Proximity Sensors, which boast the world’s longest sensing distances. The sensors enabled both detection stability for different material components and durability with the full metal body. They help enhance productivity in the automotive industry, where downtime leads large production opportunity losses, by reducing risks of sudden stoppages due to sensors occurred in the welding processes for automobiles.
Automotive industry needs lighter weight of automobiles in accordance with the trend of electric vehicles and low fuel consumption, encouraging the material change in automotive components from iron to aluminum. This will increase mixed production lines containing iron and aluminum. Full metal proximity sensors are mainly used in harsh welding processes. However, previous full metal proximity sensors have short sensing distances. In particular, the sensing distance for aluminum is shorter than the one for iron. Therefore, higher accuracy is required for installing proximity sensors for aluminum than iron, making the design, start-up, and maintenance of production lines complicated. With skilled labor shortages becoming severer, however, demand is growing for ways to maintain and enhance facility operation rates without relying on human experience or skills.
The sensing distance are approximately twice as long as previous models for iron, and six times as long as previous models for aluminum, meaning equivalent sensing distances to detect iron and aluminum components. In addition, OMRON’s technologies prevents coating abrasion which allows 60 times longer-lasting spatter resistance than previous models. The E2EW Sensors with its durable body and long sensing distance increase sensor installation flexibility, and they help enhance productivity by streamlining production lines which require skills from the start-up, operation, to maintenance.
