Inductive ringsensors made by Proxitron detect metal objects inside the ring-shaped entry. In particular the supply of small objects e.g. nails or bolts is reliably observable.
The smallest design has a mere size of 60x30x16 mm while having an outlet opening of 10,1mm up to 25,1 mm.

Special characteristics:

• simple installation (since the product fits well in a row and is easily assembled:
  stacking distance of >20mm)
• fully reliable (due to its inductive sensor technology)
• optimized to capture small parts (due to its integrated impulse extension)

Application:

• detects nails, screws, studs etc.
• ejection detection
• parts counting
• wire break monitoring
• nailing machines for plate production
• flow control in assembly technology
• congestion reporting in delivery tubing
