Motion Detectors: Precision Detection for Automated Environments
Motion detectors, also known as occupancy sensors, presence detectors, or PIR sensors (passive infrared), are essential components in modern automation and security systems. These devices detect movement within a defined area using various technologies such as passive infrared (PIR), microwave (radar), ultrasonic, or dual-technology (dual-tech) combinations. Key technical parameters include detection range (typically 2–12 meters for indoor units), detection angle (90° to 360°), mounting type (wall, ceiling, or flush-mount), and output type (relay, 0–10 V, or DALI for lighting control). Power supply voltages commonly range from 12–24 V DC or 110–240 V AC, with some models featuring adjustable time delays (from a few seconds to 30 minutes) and light-level thresholds (lux settings) to avoid false triggers. These sensors are rated with IP20 for indoor use or IP54/IP65 for outdoor installations, ensuring reliable operation in dusty or wet conditions.
Motion detectors are deployed across a wide spectrum of sectors, including residential, commercial, and industrial facilities. In building automation, they control lighting in offices, corridors, and restrooms to reduce energy consumption by up to 60%. In security systems, they trigger alarms or CCTV recording upon unauthorized movement. Industrial applications include warehouse occupancy detection for automated conveyor systems, HVAC optimization in large halls, and safety zones in robotic cells. They are also integral to smart home systems, enabling automated lighting, heating, and window shading based on occupancy patterns.
Our catalog includes several subcategories and key article codes for motion detectors. For example, the PIR sensor series with codes like MD-2000 (wall-mounted, 12 m range, 180° angle) and MD-3000 (ceiling-mounted, 360° coverage, 6 m diameter). The dual-tech series, such as DT-4000, combines PIR and microwave for reduced false alarms. The code structure typically follows: [Technology Prefix]-[Range Code]-[Mounting Type], e.g., PIR-12W for a 12-meter wall-mounted PIR. Other notable articles include the ultrasonic sensor US-5000 for open-plan offices and the outdoor detector OD-6000 with IP65 rating and pet immunity.
Partnering with Electric Automation Network ensures you receive genuine, certified motion detectors with full technical documentation, including datasheets and wiring diagrams.
