The S3231R is an inductive ring sensor designed to detect metallic objects passing through its bore, suitable for counting and automation in manufacturing systems. It has a 100 mm internal diameter, operates on a 10-30 Vdc supply with a power drain below 18 mA, and provides PNP, NO+NC outputs via a connector. The sensor features a plastic housing with IP65 protection, short circuit and reverse polarity protection, a 100 ms programmable delay, and adjustable sensitivity. Its operating frequency is 100 Hz, with repeatability under 0.3 mm, and it functions within a temperature range of -25 to +70°C. The sensor is non-flush mounted and includes an LED function indicator.
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.
