BEA Motion Radar Sensors, Voltage : 12-24VAC

Motion Radar Sensors are advanced sensing devices used in industrial automation to detect motion, speed, and presence of objects or personnel using radio wave technology. They emit microwave signals and analyze the reflected waves to identify moving targets in their detection zone. Unlike optical sensors, radar sensors work effectively in harsh environments where dust, smoke, fog, or darkness can affect visibility. Principle of Operation Motion radar sensors operate based on the Doppler Effect. The sensor transmits a continuous or pulsed microwave signal toward the detection area. When an object moves within this area, it reflects the waves back to the sensor with a frequency shift proportional to the object's speed and direction. The sensor’s internal processor analyzes this frequency shift to determine: Whether an object is moving, The speed of movement, The direction of movement (in some advanced sensors), Presence detection (even stationary objects after initial detection in some models). Components Radar Transmitter and Receiver: Emits and receives microwave signals, usually in the GHz frequency range (e.g., 24 GHz, 60 GHz). Signal Processor: Converts the received signals into actionable data such as movement detection or speed. Output Interface: Provides digital (ON/OFF), analog (distance or speed proportional), or communication signals (e.g., Modbus). Housing: Rugged and often IP-rated for industrial conditions, resistant to dust, water, and temperature extremes. Mounting Accessories: Brackets or housings for fixed or adjustable installation. Features and Advantages All-weather Operation: Functions reliably through dust, smoke, fog, rain, or darkness. Long Detection Range: Can detect motion from several meters up to hundreds of meters depending on design. Penetration Ability: Radar waves can penetrate some non-metallic materials, useful for concealed object detection. Speed Measurement: Unlike simple motion sensors, radar can measure velocity, enabling advanced control. Low False Alarm Rate: Advanced signal processing reduces false triggers from environmental noise. Wide Field of View: Configurable detection angles for specific applications. Energy Efficient: Many modern radar sensors consume low power. Industrial Applications Intrusion Detection and Security: Detect unauthorized movement in restricted areas, warehouses, or factories regardless of lighting conditions. Automated Lighting Control: Turn lights on/off in industrial buildings or outdoor areas based on detected motion to save energy. Conveyor and Material Handling Systems: Monitor movement and speed of items on conveyor belts for process control and safety. Robotics and Automated Guided Vehicles (AGVs): Detect obstacles and moving objects to avoid collisions and ensure safe navigation. People Counting and Flow Monitoring: Analyze movement patterns in factories or public facilities for safety and efficiency. Vehicle Detection: Detect movement of vehicles at entry gates or parking areas for automated barrier control. Integration with Industrial Automation Motion radar sensors output signals compatible with common automation platforms: Digital Outputs: Relay or transistor outputs for simple motion detection signals. Analog Outputs: Provide speed or distance proportional signals. Communication Protocols: Advanced models support industrial fieldbus or IoT protocols for remote monitoring and diagnostics. These sensors are connected to PLCs, SCADA systems, or building management systems to trigger alarms, control equipment, or log data for analysis. Installation Considerations Mounting Position: Optimal height and angle to cover the required detection zone without blind spots. Environmental Conditions: Choose sensors rated for the specific temperature, humidity, and exposure expected. Interference: Radar sensors can be affected by strong electromagnetic sources; proper grounding and shielding hel
