VSM103 is a three-axis MEMS acceleration sensor for industrial vibration diagnostics. It provides a -40…40 g measuring range and 0…4500 Hz frequency range. The sensor uses an IEPE interface and compact stainless-steel housing. Its short 0.3 m PUR cable is terminated with an M12 connector. The sensor is designed for connection to external vibration diagnostic electronics.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VSM103 detects vibration across three measurement axes. Capacitive MEMS technology provides dynamic machine vibration measurement. The 100 mV/g sensitivity enables detailed signal acquisition. Multi-axis monitoring supports radial and axial machine analysis. It is suitable for predictive maintenance applications.
The sensor uses a compact stainless-steel body. A mounting screw provides mechanical fixation. The sensor has IP67, IP68 and IP69K protection. It withstands industrial vibration and shock conditions. Drag-chain suitability supports applications requiring cable movement.
VSM103 provides IEPE communication to external evaluation electronics. Its 0.3 m PUR cable terminates in a five-pin M12 connector. The cable is shielded to improve signal integrity. A dedicated self-test connection supports diagnostic functionality. This makes the sensor suitable for integrated vibration-monitoring systems.
