Function and features
This inductive sensor detects metals without contact and indicates their presence by
providing a switched signal.
The nominal sensing range (Sn) can be seen in the type designation on the type
label on the unit; operating distance (Sa) 0 ... 0,81 x Sn; (values based on standard
measurement with mild steel; a shorter sensing range for other metals).
Electrical connection
Disconnect power before connecting the sensor. Connection strictly to the indications
on the type label. The unit can be used as normally open ( ) or as normally
closed ( ).
Installation
Mounting by means of a mounting device.
Adjust the unit. Adjustment is correct
when the red LED does not light. Secure
by means of the nuts provided so that it
cannot work loose.
Non-flush installation.

Operation
Check the safe functioning of the sensor. Display by LEDs:
The yellow LED is lit when the output is switched.
The red LED is lit in case of faulty adjustment.

LED yellow No object in the detection range.
LED red
LED yellow Safe detection of the object.
LED red
LED yellow Unsafe detection of the object
(readjust the unit).
LED red
LED yellow Uncertain function: predamping of the
unit by metal deposits or insufficient
open space around the active face;
(clean the active face or readjust the unit).
LED red
The operation of the sensor is maintenance-free.
For perfect functioning make sure that:
the sensing face and the open space are kept free of metal deposits and foreign
bodies, particularly for installation with the sensing face facing upwards;
EMC: The unit conforms to the requirements of EN 60947-5-2.
