Baumer inductive proximity sensor, specifically identified by the "Baur 0920" marking visible on the device.
Here's some information about inductive proximity sensors:
Function: Inductive proximity sensors are non-contact electronic sensors that detect the presence of metal objects without physical contact.
Applications: They are widely used in industrial automation for position sensing, counting, and control applications.
Features: They are typically available in various designs and sizes, with different sensing distances and connection types (e.g., cable or plug).
