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. |
