| High Light | 24.125GHz Doppler detector ，microwave motion sensor with planar antenna ，temperature resistant motion detector | ||
This 24.125GHz Doppler Detector is a high-adaptability motion sensing solution for automatic door, commercial access and light industrial automation scenarios, engineered with a high-gain planar antenna, robust temperature resistance and fully adjustable sensitivity—delivering consistent, tailored performance across diverse environmental and usage conditions. Tuned to the reliable 24.125GHz microwave band, its integrated planar antenna is optimized for uniform signal transmission, creating a smooth, blind-spot-free detection field that captures motion targets moving at ≥5cm/s with clear, unbroken signals; the antenna’s design also enhances signal focus, avoiding over-sensing of irrelevant areas and ensuring precise detection aligned with your specific setup, whether mounted at the standard 2.2m height or max 3m for commercial entryways.
A key advantage is its exceptional temperature resistance, operating stably in an extreme range of -20℃ to +55℃ without signal drift or performance degradation. It performs reliably in cold outdoor covered entryways during winter, hot indoor commercial spaces like mall atriums in summer, and even temperature-fluctuating industrial areas, far outpacing ordinary detectors in environmental adaptability. The customizable sensitivity feature lets you fine-tune the detection range via a gentle-rotate potentiometer—lower sensitivity for narrow passageways to prevent false triggers from ambient movement, or raise it for high-traffic zones to ensure full coverage—no professional tools or technical expertise required for calibration.
Built for long-term usability, this detector features an IP54 dustproof and waterproof rating, resisting daily splashes and dust accumulation, with ultra-low power consumption (≤2W) and 12-24V AC/DC wide voltage compatibility for seamless integration with existing control systems. A clear LED status indicator provides real-time power and detection feedback for quick setup and troubleshooting, and it complies with R&TTE and EMC international standards for interference-free operation near neon lamps and electronic equipment. Blending planar antenna precision, all-climate temperature resistance and flexible sensitivity, this 24.125GHz Doppler Detector is a versatile, low-maintenance motion sensing choice for diverse commercial and light industrial applications.
