Ultrasonic proximity switch with one switching output and IO-Link
lcs+340/F/A
lcs+600/F/A
Product Description
The lcs+ sensor offers a non-contact measurement of the distance to an object which must be positioned within the sensor’s detection zone.
The switching output is set conditional upon the adjusted detect distance. Via the Teach-in procedure, the detect distance and operating mode can be adjusted. One LED indicates operation and the state of the switching output.
The lcs+ sensors are IO-Link-capable in accordance with IO-Link specification V1.1 and support Smart Sensor Profile like Digital Measuring Sensor.
Safety Notes
- Read the operating manual prior to start-up.
- Connection, installation and adjustments may only be carried out by qualified staff.
- No safety component in accordance with the EU Machine Directive, use in the area of personal and machine protection not permitted.
Proper Use
lcs+ ultrasonic sensors are used for non-contact detection of objects.

Installation
- Mount the sensor at the place of fitting.
- Connect a connection cable to the M12 device plug, see Fig. 1.
Start-up
- Connect the power supply.
- Set the parameters of the sensor, see Diagram 1.
Factory setting
- Switching output on NOC
- Detect distance at operating range
Operating Modes
Three operating modes are available for the switching output:
- Operation with one switching point
The switching output is set when the object falls below the set switching point. - Window mode
The switching output is set when the object is within the window limits. - Two-way reflective barrier
The switching output is set when the object is between sensor and fixed reflector.

Synchronisation
If the assembly distance of multiple sensors falls below the values shown in Fig. 2, the internal synchronisation should be used. For this purpose set the switching outputs of all sensors in accordance with Diagram 1. Finally interconnect each pin 5 of the sensors to be synchronised.
Maintenance
microsonic sensors are maintenancefree. In case of excess caked-on dirt we recommend to clean the white sensor surface.
Notes
- The sensors of the lcs+ family have a blind zone, within which a distance measurement is not possible.
- The lcs+ sensors are equipped with an internal temperature compensation. Due to the sensors self heating, the temperature compensation reaches its optimum workingpoint after approx. 30 minutes of operation.
- In the normal operating mode, an illuminated yellow LED signals that the switching output is switched through.
- The lcs+ sensors have a push-pull switching output.
- In the »Two-way reflective barrier« operating mode, the object has to be within the range of 0-85 % of the set distance.
- In the »Set detect point – method A« Teach-in procedure the actual distance to the object is taught to the sensor as the detect point. If the object moves towards the sensor (e.g. with level control) then the taught distance is the level at which the sensor has to switch the output.
- If the object to be scanned moves into the detection area from the side, the »Set detect point +8 % – method B« Teach-in procedure should be used. In this way the switching distance is set 8 % further than the actual measured distance to the object. This ensures a reliable switching distance even if the height of the objects varies slightly.

| detection zones for different objects: The dark grey areas represent the zone where it is easy to recognise the normal reflector (round bar). This indicates the typical operating range of the sensors. The light grey areas represent the zone where a very large reflector–for instance a plate – can still be recognised. The requirement here is for an optimum alignment to the sensor. It is not possible to evaluate ultrasonic reflections outside this area. |
