Inductive Ring Sensors

Ø 10 - 270 mm

Detection of metallic objects

Nails - Welding bolts - Counting of parts - Ejection monitoring - Wire crack indication

The response sensitivity can be adjusted. The nominal sensitivity is referred to a ball of steel (St37). In case of pins or wires considerably smaller diameters are detected. Brass, aluminium or copper reduce the sensitivity.

The output of the ring sensor operates statically, the output is switched as long as a metallic object is in the aperture. When objects fall through the ring sensor quite quickly the output pulses can be very short. The optional pulse extension acts as an adjustable switch-off delay and enables reliable detection even with very short dwell times for the connected signal processing.
