All description
Manufacturer: Pepperl+Fuchs
Description:

Inductive proximity sensors are essential components in automation technology, enabling non-contact detection of metallic objects. These sensors operate on the principle of electromagnetic induction, generating an oscillating electromagnetic field that can detect changes caused by nearby metallic materials. This functionality makes them highly effective in numerous applications, including position sensing, object counting, and speed monitoring.

The sensors in this product family feature durable housing materials such as PA and LCP, ensuring longevity and reliability even in harsh environments. With a rated operating distance of 20 mm and a flush installation design, they can be easily integrated into a variety of machinery and equipment. The 4-wire output configuration allows for straightforward connections and compatibility with various control systems, making them a versatile choice for industrial automation tasks.
