Radar sensors

Your Benefits

  • Quick and precise object detection
  • Monitored areas can be adapted individually to applications
  • Freely programmable transistor outputs for quick, break-free and stable data transmission
  • Output of identification number, speed and direction of movement of the object via Ethernet
  • Simultaneous determination of object distance and speed as well as the angle between sensor and object
  • Simple configuration and installation


The RMS3xx radar sensor combines the high-performance radar technology from SICK on a foundation of trusted hardware and efficient software. The sensor reliably identifies objects such as obstacles within its detection range. It not only outputs the identification number of the object, but also its direction of movement, speed and distance to the sensor. Thanks to the individually adjustable monitored areas, the RMS3xx identifies objects on-time, e.g. to detect collision risks for driver assistance systems in a timely manner and prevent damage. Simultaneous detection of several objects and provision of associated object data secure operation even in areas in which several objects have to be monitored or in harsh environments.

At a glance
  • Detection of static and movable objects
  • 4 freely programmable transistor switching outputs
  • Output of identification number, speed, direction of movement of the object via Ethernet
  • Large scanning range for detection angles of ± 50° (azimuth) and ± 8° (elevation)
  • Dust-free, waterproof housing (IP67)


Modern FMCW radar technology for industrial use

The RMS3xx is one of the world’s first 2D radar sensors that was designed for industrial use and consistently geared to the application requirements of countless branches. Not least due to the use of extremely powerful algorithms adapted to industrial applications, the RMS3xx stands out due to its detection performance, especially under very harsh ambient and weather conditions such as fog, rain, snow, dust and extreme temperatures.
The RMS3xx is not influenced even by rain, fog, dust, snow and extreme temperatures and is independent of light influences. The sensor can therefore be used during the day or night.
The FMCW (FMCW = frequency modulated continuous wave) technology enables the RMS3xx, in combination with object tracking, to detect the spacing, horizontal angle, radial speed, movement pattern and direction of movement of objects at the same time.

High availability even under very unfavorable ambient conditions and very good reliability when detecting objects

SICK LifeTime Services

SICK’s services increase machine and plant productivity, enhance the safety of people all over the world, provide a solid foundation for a sustainable business operation, and protect investment goods. In addition to its usual consulting services, SICK provides direct on-site support during the conceptual design and commissioning phases as well as during operation.

The range of services not only covers aspects like maintenance and inspection, but also includes performance checks as well as upgrades and retrofits. Modular or customized service contracts extend the service life of plants and therefore increase their availability. If faults occur or limit values are exceeded, these are detected at all times by the corresponding sensors and systems.

Consulting and design Application-specific advice on the product, its integration and the application itself.
Commissioning and maintenance Application-optimized and sustainable ─ thanks to professional commissioning and maintenance by a trained SICK service technician.
Service contracts Extended warranty, SICK Remote Service, 24-hour helpdesk, maintenance, availability guarantees and other modular components can be individually combined on request.
