The Ring DC 4 Wire Inductive Ring Sensor, part number S3219R, is designed for detecting metallic objects passing through its sensing area. It operates on a supply voltage of 10-30 Vdc and features NPN or PNP outputs with normally open and normally closed configurations. The sensor is equipped with adjustable sensitivity, a delay ON/OFF switch, and an LED function indicator. It provides short circuit and reverse polarity protection, ensuring reliable operation in various environments. This sensor is housed in a rugged plastic casing with an IP65 protection rating, making it dust-tight and resistant to water jets. It is available with pre-wired cable or connector output options, with cable lengths of 2 meters standard, and longer lengths available upon request. The sensor is suitable for applications involving the detection, counting, and inspection of small metal parts, such as screws and washers, and is effective in machine tool automation and manufacturing systems. The operating temperature range is -25 to +70¬8C (-13 to 158¬8F), and the sensor's performance is influenced by the shape and size of the metallic target.
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.
