Narrow-Beam FMCW Radar Sensor

Service Description

End Product + Design Documents + Production Documents

This radar-based sensor utilizes true-presence FMCW (Frequency Modulated Continuous Wave) technology to reliably detect both moving and stationary objects. Designed with a narrow beam pattern and high sensitivity, it offers precise target detection while minimizing interference from surrounding areas.

Key features include:

• Adjustable detection range and sensitivity, allowing the sensor to ignore objects beyond a user-defined threshold.
• Simple configuration via DIP switches for quick setup of range, sensitivity, and output parameters.
• Environmental resilience, ensuring consistent operation regardless of wind, rain, snow, fog, humidity, extreme temperatures, or lighting conditions.
• Operates within the ISM (Industrial, Scientific, and Medical) band, making it suitable for a wide range of industrial applications.
• Encased in a durable IP67-rated housing for long-lasting performance in harsh environments.

Ideal for use in traffic monitoring, security systems, industrial automation, and outdoor detection applications.
