Radar Sensor for Industrial Object Detection

Product Specifications

Technical details and manufacturing context for Radar Sensor

Definition

A radar sensor is an electronic measurement device that operates by transmitting radio frequency electromagnetic waves and analyzing the reflected signals to determine the presence, range, velocity, and angle of objects within its detection field. It functions independently of light conditions and is capable of penetrating various non-metallic materials like fog, dust, and plastic, making it suitable for applications requiring reliable object detection in challenging environments. The sensor is designed for integration into industrial systems, with a compact form factor and multiple output interfaces for data communication. It operates in the 24–24.25 GHz frequency band, compliant with FCC Part 15.245, and offers a maximum range of 100–250 meters with a range resolution of 0.1–0.5 meters. The update rate ranges from 10 to 50 Hz, and the azimuth field of view spans ±60 to ±90 degrees. The sensor supports CAN, RS-485, and Ethernet interfaces, conforming to ISO 11898 for CAN. It requires a DC supply voltage of 9–36 V, operates over a temperature range of -40 to 85 °C, and has an ingress protection rating of IP67 to IP69K, suitable for harsh environments including high-pressure washdown. Power consumption is 5–15 W, and the device weighs between 200 and 500 grams, with dimensions ranging from 80×60×30 mm to 120×80×40 mm. Typical materials include a printed circuit board, semiconductor MMIC, antenna elements, plastic/polymer housing, and metal shielding. The sensor is intended for use in industrial applications such as level measurement, traffic monitoring, and safety systems. For any specific model, verify all parameters and standards with the legal manufacturer or supplier.

Working Principle

The sensor operates on the principle of radar (Radio Detection and Ranging). It generates and emits a modulated radio frequency signal via a transmitter. When this signal encounters an object, a portion is reflected back towards the sensor. The receiver captures this echo. By analyzing the time delay between transmission and reception (Time of Flight), the distance to the object is calculated. The Doppler shift in the frequency of the returned signal is used to determine the object's radial velocity. Advanced signal processing techniques interpret the amplitude, phase, and frequency of the echo to provide detailed information about the target.

Components / BOM

Radio Frequency Integrated Circuit (RFIC/MMIC)
Generates the transmitted radio frequency signal and processes the received echo signal. It contains the oscillator, mixer, amplifier, and often an Analog-to-Digital Converter (ADC).

Material: Semiconductor (Gallium Arsenide or Silicon Germanium)
Antenna Array
Radiates the transmitted electromagnetic waves into space and collects the reflected waves from targets. Its design determines the beam shape and directivity.

Material: Copper on PCB substrate or stamped metal
Digital Signal Processor (DSP)
Executes algorithms (e.g., FFT, CFAR) on the digitized signal to extract target information like range, speed, and angle. It handles data processing and filtering.

Material: Semiconductor (Silicon)
Power Management Unit
Regulates and supplies stable DC voltage levels from the input power source to all other components within the sensor.

Material: Semiconductor (Silicon) with passive components (capacitors, inductors)
Housing / Radome Part
Provides mechanical protection, environmental sealing (IP rating), and electromagnetic shielding. The radome portion is transparent to RF signals.

Material: Plastic (e.g., ABS, PBT) or metal alloy for shielding
