Description:

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.

SELECTION OF RING SENSOR: Select the minimum ring diameter required. This enables the sensitivity adjustment to be made within normal parameters ensuring proper functioning of the unit.
SENSITIVITY ADJUSTMENT: After selection of the ring diameter, it is recommended that the sensitivity adjustment be made while the sensor is installed in its final position, enabling any surrounding metal to be taken into account. Sensitivity increases by turning the trimmer clockwise and decreases by turning it counterclockwise.
EFFECTS OF METAL IN THE CLOSE VICINITY: Moving metal parts close to the sensing area can affect the performance of the sensor. In order to ensure proper functioning, mount the sensor away from metallic objects.
USE OF SENSOR: A distance equal to the width of the sensor should be left between each object that passes through the sensor. If more than one sensor is to be installed in close vicinity, the minimum distance indicated between sensors should be observed.
