microsonic crm plus Ultrasonic Sensors with One Analogue Output
Specifications:
- Model Variants: crm+25/IU/TC/E, crm+35/IU/TC/E, crm+130/IU/TC/E, crm+340/IU/TC/E, crm+600/IU/TC/E
- Output: One analogue output
- Transducer Surface: Laminated with PEEK film
- Additional Features: Three-color LEDs, Teach-in procedure, Add-on menu
Product Description:
The crm+ sensor with one analogue output measures the distance to an object
within the detection zone contactlessly. The sensor creates a signal
proportional to distance based on the adjusted window limits of the analogue
characteristic curve. The ultrasonic transducer surface is sealed against the
housing by a PTFE joint ring, providing high resistance against aggressive
substances.
Usage Instructions
Setting up the Sensor:
- Press T1 and T2 simultaneously for about 3 seconds until the welcome message has passed.
- Use T1 and T2 buttons to set the sensor-close window limit in mm or cm.
- Set the sensor-distant window limit using T1 and T2 buttons.
- Choose between rising or falling output characteristic curve using T1 and T2 buttons.
Proper Use and Safety Notes:
crm+ ultrasonic sensors are designed for non-contact detection of objects.
Always read the operating instructions before startup. Connection,
installation, and adjustment should be done by expert personnel only. Do not
use the sensor in areas related to personal and machine protection as it does
not comply with safety regulations.
Synchronization:
If using multiple sensors, ensure the assembly distance is within specified
values for synchronization. Connect Sync/Com channels of all sensors for
proper operation.
Multiplex Mode Installation:
Refer to Fig. 1 for assembly distances and synchronization/multiplex
information. Follow the pin assignment as shown in Fig. 2 for correct
installation.
Factory Settings:
The crm+ sensors are factory set with a rising analog characteristic and
window limits already configured.
crm+ Ultrasonic Sensors with one analogue output
- crm+25/IU/TC/E

- crm+340/IU/TC/E
- crm+600/IU/TC/E
Product Description
- The crm+ sensor with one analogue output measures the distance to an object within the detection zone contactless. A signal proportional to distance is created according to the adjusted window limits of the analogue characteristic curve.
- The ultrasonic transducer surface of the crm+ sensors is laminated with a PEEK film. The transducer itself is sealed against the housing by a PTFE joint ring. This composition ensures a high resistance against many aggressive substances.
- All settings are done with two pushbuttons and a three-digit LED display (TouchControl).
- Three-colour LEDs indicate all operation conditions.
- Choosing between rising and falling output characteristic is possible.
- The sensors are adjustable manually via TouchControl or via Teach-in procedure.
- Useful additional functions are set in the Add-on menu.
- Using the LinkControl adapter (optional accessory) and the LinkControl software for Windows®, all
Teach-in and additional sensor parameter settings can be optionally undertaken. The crm+ sensors have a blind zone in which distance measurement is not possible. The operating range indicates the distance of the sensor that can be applied with normal reflectors with sufficient function reserve. When using good reflectors, such as a calm water surface, the sensor can also be used up to its maximum range. Objects that strongly absorb (e.g. plastic foam) or diffusely reflect sound (e.g. pebble stones) can also reduce the defined operating range.
Safety Notes
- Read the operating instructions prior to start-up.
- Connection, installation and adjustment works may only be carried out by expert personnel.
- No safety component in accordance with the EU Machine Directive, use in the area of personal and machine protection not permitted
Proper Use
crm+ ultrasonic sensors are used for non-contact detection of objects.
Synchronisation
If the assembly distance of multiple sensors falls below the values shown in
Fig. 1 the integrated synchronisation should be used. Connect Sync/ Com-
channels (pin 5 at the units receptable) of all sensors (10 maximum).
Multiplex mode
The Add-on-menu allows to assign an individual address »01« to »10« to each
sensor connected via the Sync/ Com-channel (Pin5). The sensors perform the
ultrasonic measurement sequentially from low to high address. Therefore any
influence between the sensors is rejected. The address »00« is reserved to
synchronisation mode and deactivates the multiplex mode. To use synchronised
mode all sensors must be set to address »00«.
Installation
- Assemble the sensor at the installation location.
- Plug in the connector cable to the M12 connector, see Fig. 2.
Start-up
- Connect the power supply.
- Set the parameters of the sensor manually via TouchControl (see Fig. 3 and Diagram 1)
- or use the Teach-in procedure to adjust the detect points (see Diagram 2)
Factory setting
crm+ sensors are delivered factory made with the following settings:
- Rising analogue characteristic
- Window limits for the analogue output set to blind zone and operating range
- Measurement range set to maximum range
Maintenance
crm+ sensors work maintenance free. Small amounts of dirt on the surface do not influence function. Thick layers of dirt and caked-on dirt affect sensor function and therefore must be removed.
Notes
- As a result of the design the assembly of PEEK film and PTFE joint ring is not gas-proof.
- The chemical resistance has to be tested experimentally if necessary.
- crm+ sensors have internal temperature compensation. Because the sensors heat up on their own, the temperature compensation reaches its optimum working point after approx. 30 minutes of operation.
- If an object is within the set window limits of the analogue output, then LED D1 lights up green, if the object is outside the window limits, then LED D1 lights up red.
- The load put to the analogue output is detected automatically when turning supply voltage on.
- During normal mode operation, the measured distance value is displayed on the LED-indicator in mm (up to 999 mm) or cm (from 100 cm). Scale switches automatically and is indicated by a point on top of the digits. Alternatively, a percentage scale may be set in the add-on menu. In this connection 0 % and 100 % correspond to the set window limits of the analogue output.
- If no objects are placed within the detection zone the LED-indicator shows »– – –«.
- The sensor can be set to its factory setting, see Diagram 3.
- If no push-buttons are pressed for 20 seconds during parameter setting mode the made changes are stored and the sensor returns to normal operating mode.

In normal operating mode shortlypush T1. The LED display shows »PAr.« Each
time you tap push-button T1 the actual settings of the analogue output are
shown.

FAQ
Q: What is the purpose of the three-color LEDs on the sensor?
A: The three-color LEDs indicate various operation conditions of the sensor.
Q: Can the sensor measure distances through materials that absorb sound?
A: Objects that strongly absorb sound may reduce the defined operating range
of the sensor.
