●GENERAL CHARACTERISTICS
In ring sensors, sensing is made within the ring itself. The sensors is activated when a metallic object is introduced within it. They are particularly suitable for applications where detection of small metal objects such as screws, nuts, washers etc...is requested and also for break detection of continuos metal wires that pass through it.
●USE WITH A DELAYED AMPLIFIERS
All types of ring sensor can work in combination with a delayed amplifier of the programmable ALTP series which ensures the sensing of small object in rapid movement.

●EFFECTS OF METAL IN THE CLOSE VICINITY
If a moving metal part is close to the sensing area the functioning can be disturbed. In Order to avoid this , install the units some distance from metallic object. Ensure that this dose not interfere with the functioning.

●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.
●SELECTION OF RING SENSOR
Selection should be made based on the minimum hole diameter required. In this way the sensitivity adjustment can be made within normal parameters

●SENSITIVITY ADJUSTMENT
After having followed the instructions regarding the choice of the most suitable unit it is recommended that the sensitivity adjustment be carried out when the sensor is installed in the final position taking into account how much metal mass is close by which could alter its functioning .The sensitivity increases turning the trimmer clockwise.
●SWITCHING FREQUENCY

The switch frequency of inductive ring sensors depends on delayed impulse time (when inserted) according to the formula:
Switching frequency (Hz) = 1/(T impulse+10) ms
Vice versa, switching frequency will be as per chart beside.

●DELAY ON DE-ENERGIZATION
All our inductive ring sensors, NPN and PNP amplified versions, are supplied with an ON-OFF switch to activate and disactivate delay on de-energization 100ms.This delay allows the sensor to detect small metallic objects passing rapidly through the sensitivity area of the ring.
