Ring sensors control the feed of screws, nails, and similar small parts. Their output is static, i.e. it remains active as long as there is a metal part in the detection range.
Benefits
Easy installation (can be mounted side-by-side and universally, stacked with a gap of > 20 mm)
Extremely reliable due to inductive sensor principle
Ideal for the detection of small parts (with integrated pulse extension)
Applications
Detection of nails, screws, welded studs, and similar
