Many industries need to use multiple metals during manufacturing and processing. However, complications can arise when different types of metals are used with standard inductive proximity sensors. If a metal is less ferrous (less magnetic), for example, a larger proximity sensor may have to be used or the sensor may have to be moved closer to the object being detected. Production must stop to exchange and/or move the proximity sensor, using up valuable time. Reduction factor 1 (R1) inductive sensors eliminate this problem and increase productivity. Here are a few of the ways they can be applied:
Weld-immune R1 sensors with IP68 protection, like the new NRB8-18GM40-E2-IO-C-V1 from Pepperl+Fuchs, can be applied during electric welding operations. These sensors are immune to the electromagnetic fields that are generated during the welding process, ensuring that no interference occurs between the weld field and the sensor.
2) Automotive Assembly:
Multiple metals are used in vehicle construction. With R1 inductive sensors, the operating distances and switching frequencies remain the same for all metals. This means assembly can operate continuously and the position of car doors or skids can be reliably detected.
3) Food and Beverage Industries:
All food and beverage companies are required to conduct intensive washdowns on a daily basis. R1 inductive proximity sensors with V4A stainless steel housings made of FDA-certified LCP plastics withstand the harsh cleaning agents, high pressure, and high temperatures present in washdown areas to provide reliable detection.
4) Conveyer Systems:
Since R1 sensors are available in various sizes, they can be used to fit into areas under or alongside conveyer systems. The sensor’s output pulse extension feature can ensure that fast-moving targets will be detected by the control system, making it an optimal choice for detecting parts traveling on conveyor systems.
5) Error Proofing and Part Detection:
In all automated applications, accurate machine sequencing cycles are a must. This is required to prevent downtime and unverified process completion. R1 sensors can provide timely communication of the sensor process data via the IO-Link network, helping to ensure overall equipment performance.
