of use.
- ifm electronic gmbh hereby declares that the device LW2120 is in compliance with Directive 2014/53/EU.
- The full text of the EU Declaration of Conformity, technical data, instructions, approvals, contacts and further information at documentation.ifm.com.
- In case of operation with an activated 10-Link interface, EMC category Class A applies for the unit, otherwise Class B. For class A. the following warning must be observed: This unit is not intended to be used in residential areas and cannot ensure adequate protection of radio reception In such environments.
- The unit transmits in the frequency band 77 to 81 GHz with a max. transmission power of 3 dBm.
- Due to radio frequency exposure limits this device should be instated and operated with a minimum distance of 20 an between the device and the body of the user or nearby persons.
- The device emits radio waves that may interfere with the operation of electronic devices in the vicinity, Including pacemakers, hearing aids and defibrillators. If you have a pacemaker or other implanted medical device, do not use the sensor without first consulting your doctor or the manufacturer of your medical device. Keep a safe distance between the device and your medical products and refrain from further use of the device if you observe permanent impairment of your medical devices.
Open air Installations (LPR, Level Probing Radar)
This device when fitted with the antenna extension E33705 complies with ETSI
EN 302 729 and EN 62311.
For open air installations, restrictions exist in several EV and EFTA member
states in the proximity of Radio Astronomy sites. Locations of Radio Astronomy
sites completely or partially using the same frequency band as LW2120 (77 to
81 GHz) vary over time. Therefore, the Installer and the user of LW2120 is
obligated to check if their installation location is affected.
The current list of Radio Astronomy sites including their corresponding operating frequencies may be found at www.craf.eu. The following restrictions apply to affected installation locations:
- Install at a separation distance of > 4 km from Radio Astronomy sites measuring at 77-81 GHz, unless a special authorization has been provided by the responsible National regulatory authority.
- Between 4 km to 40 km around any Radio Astronomy site the LPR antenna height shall not exceed 15 m height above ground.
Closed tank installations (TLPR, Tank Level Probing Radar)
- This device without the antenna extension complies with ETSI EN 302 372 and EN 62311.
- The device must be installed in closed tanks (metal, reinforced concrete tanks or similar enclosure structure made of comparable attenuating material). Install according to requirements in ETSI EN 302 372 (Annex E).

Radio approval South Korea
FCC ID: UN6-LW2120
IC: 6799A-LW2120
Non Contact Level Transmitter:
This device contains licence-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science and Economic Development Canada’s licence-exempt
RSS(s) and complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference
that may cause undesired operation of the device.
Changes or modifications made to this product not expressly approved by ifm
electronic gmbh could void the user’s authority to operate this product. This
equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna
- Increase the separation between the equipment and receiver
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help
Radiofrequency radiation exposure information
This equipment complies with FCC and ISED radiation exposure limits set forth
for an uncontrolled environment. This equipment should be installed and
operated with minimum distance of 20 cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
Use in Closed Tank Installations
- This device is designed to measure the level of liquid media in an enclosed space.
- Installations shall only be in metal tanks, concrete tanks or enclosures with similar attenuating properties.
