The SW-200D-15A10G is a vibration sensor with ROHS (Restriction of Hazardous Substances) compliance, manufactured by XKB. This vibration sensor is capable of detecting tiny vibrations and movements in metal objects over wide areas. It utilizes a piezoelectric transducer to detect movement and generate electrical signals that can then be monitored and analyzed. The sensor is small in size and lightweight, making it a great choice for applications that require high-sensitivity vibration sensing in tight and confined spaces. The sensor is also RoHS compliant, making it suitable for use in applications that require compliance with environmental and safety regulations.
