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, dirt-resistant, plastic housing with a protection degree of IP65.
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.
The operating distance of the sensor depends on the actuator shape and size and is strictly linked to the nature of the metal.
Choosing an inductive Ring sensor is as easy as follows …
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 surround metal to be considered.
Sensitivity increases by turning the trimmer clockwise and decreases by turning it counterclockwise.
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.
The devices are protected against overload, short circuit and reverse polarity. They generate an output signal when there is metal in the detection zone, so for example they can be used for jam control in feed processes.
