The TURCK BS4140-0/9 is a cylindrical inductive proximity switch designed for use in explosion-prone or intrinsically safe areas. It features a NAMUR (2-wire) output suitable for Ex-compliant applications. Housed in a robust cylindrical brass body, this sensor is ideal for reliable metal object detection in environments where standard proximity switches are not safe to use. Its compact design, high resistance to environmental stress, and long switching life make it suitable for heavy-duty sensing tasks in process automation and safety applications. Key Features: • Inductive proximity sensor with NAMUR output (2-wire) • Cylindrical housing – compact form factor • Brass construction for industrial durability • Suitable for use in Ex-rated hazardous areas • Reliable metal detection in intrinsically safe circuits • High switching precision and long service life • Ideal for process automation and explosion-proof zones
