Murata launches vibration sensor device for predictive maintenance capable of detecting high-frequency range up to 20 kHz

　　Murata Manufacturing Co., Ltd. announces the SMD-type vibration sensor device PKGM-210D-R. Mass production has already begun.

　　In the factory automation (FA) industry, maintenance has traditionally consisted of scheduled maintenance at fixed intervals and corrective maintenance after failures.

　　In recent years, however, predictive maintenance, which detects early signs of failure to prevent unexpected equipment stoppages, has become increasingly important. In rotary machinery such as bearings and motors, component damage or insufficient lubrication generates minute abnormal vibrations in the high-frequency range up to 20 kHz before failures become serious. Measuring such high-frequency vibrations is challenging due to interference from noise, and detection has often relied on the experience of skilled technicians using auditory inspection.

　　By combining its long-established piezoelectric ceramic vibration detection technology with advanced circuit packaging expertise, Murata has developed the PKGM-210D-R, capable of detecting vibrations up to 20 kHz, the upper limit of the audible range. This enables detection of subtle high-frequency abnormal vibrations that were previously identified only by human hearing.

　　The product supports early prediction of equipment issues, helping to reduce downtime, optimize maintenance timing, extend component life, and minimize excess inventory. In addition, its compact size of 0.20 × 0.20 × 0.14 inches (5.0 × 5.0 × 3.5 mm) allows easy retrofitting to existing equipment or direct integration into motor components.

　　Key features:

　　Z-axis direction detection up to 20 kHz

　　Compact size (0.20 × 0.20 × 0.14 inch / 5.0 × 5.0 × 3.5 mm) for easy retrofit and built-in mounting

　　Built-in driver and filter circuits

　　Versatile single analog output

　　Built-in temperature sensor
