The S3220R is an inductive ring sensor designed to detect metallic objects passing through its annular sensing area, suitable for applications such as part counting and machine automation. It features a plastic housing with IP65 protection, operates on a 10-30 Vdc supply, and provides NPN or PNP, NO+NC outputs via a Type C connector. The sensor has a 22 mm internal diameter, a switching current of 200 mA, a voltage drop under 1.8 Vdc, and a power drain under 18 mA. It offers adjustable sensitivity, a 100 ms output delay, and short circuit and reverse polarity protection. Operating frequency is 600-800 Hz, with repeatability under 0.3 mm. The operating temperature range is −25 to +70°C. Flush mounting is not supported.
Features:
In inductive ring sensors, the sensing area is located inside the ring. These sensors are designed to detect metallic masses entering or passing through the ring. They are ideal for sensing, counting and checking of small metal parts such as: screws, washers, nuts etc. and the control, detection, position, inspection and automation of machine tools & manufacturing systems.
They operate on a 10-30 Vdc supply and offer NPN or PNP, NO+NC outputs. They are sealed in a rugged, plastic housing with a protection degree of IP 65. All versions have short circuit and reverse polarity protection and are available in either prewired cable or connector output connection. Each unit is supplied with a sensitivity adjustment and a delay ON/OFF switch that fixes the output pulse for 100mS. This makes them ideal for detection of fast moving small metal objects. Special version NAMUR output is available.
The operating distance of the sensor depends on the actuator shape and size and is strictly linked to the nature of the metal. For minimum target size, see Table 1.
