IMR Weld Field Immune Inductive from SICK
February 19, 2019
SICK is now offering a line of inductive sensors that are not the least bit bothered by magnetic interference or weld splatter, and a rugged PTFE and Factor 1 sensing guarantee the highest operational safety. This is why they are one of the top choices for use in the automotive industry!
The IMR inductive proximity sensors are not the least bothered by magnetic interference fields or weld spatter, such as arise in resistance welding applications. IMR sensors are made without a ferrite core, which makes them magnetic field resistant, and also have a very high electromagnetic compatibility. Thanks to the rugged non-stick coating made from PTFE, these sensors provide very good protection against flying sparks and slag deposits, thereby guaranteeing a high operational safety. Since IMR sensors operate on the reduction factor 1 principle, they can detect all metals within the same sensing range. The very high sensing ranges of up to 75 mm help reduce mechanical damage to the sensors and therefore sensor failures, and increase plant availability.
Wear-free and in practical terms unaffected by external influences, inductive proximity sensors detect the presence and distance of metallic objects. This means they are ideally suitable for a variety of detection, counting and positioning tasks in factory automation.
The most important requirements for inductive sensors are precision, maximum availability, and a long service life. Inductive sensors from SICK pack advanced technology into the smallest of spaces. Due to improved production tolerances, SICK sensors with ASIC technology deliver much higher precision than standard discretely mounted devices. They are not digitally synchronized until after the production process is complete, essentially ruling out production-related tolerances of the sensing range.
