Type Selection
Capacitive level detector with specialized and opti­mized features for level detection in plastic and rub­ber applications. The sensor will adapt auto­matically to the application when power-on for the first time. The adjustment is easy to change by means of the
remote teach-in function. The sensor front can with­stand temperatures up to 120
°C. 3-wire DC output with selectable make (NO) or break (NC) switching. Grey polyester housing with 2 m PVC cable or M12 plug (Only M30).

Wiring Diagram
The PNP- or NPN-load will automatically be detected.
Always connect the white wire to (+) supply for running mode (Locked setup)
Installation
First time calibration
Install and wire the sensor according to the above wiring diagram. Remember to connect the white wire, the 4th wire, to (+) supply The very first time the sensor is powered up, the sensor will
automatically adapt to the surroundings and calculate an optimal sensitivity by itself – no matter what kind of plastic material to be detected. As long as the white wire is connected to (+) supply, the sensor will be locked and be in running mode.

Locked sensor set-up
No other adjustment is needed. As long as the white wire is connected to (+) supply, the set-up of the sensor is locked, and will not change during another power down/up.

Re-calibration of the sensor
If needed, a new Self-Teach can be activated by discon­necting the white wire from (+) supply, and then connect it again to (+) supply.
You have now activated a new Self-Teach and the sensor will now re-calibrate and calculate a new sensitivity accord­ing to the application. Be sure that the application is empty – no object to detect.

Installation Hints
Dimensions
Relief of cable strain
Protection of the sensing face Switch mounted on mobile carrierTo avoid interference from inductive voltage/ current peaks, separate the prox. switch pow­er cables from any other power cables, e.g. motor, contactor or solenoid cables
Not correct
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the cable should be avoided
