The IFM VSA205 is a high-range single-axis MEMS acceleration sensor for vibration detection. It measures -150 to +150 g across a 1–10,000 Hz frequency range. The sensor provides a 0–10 mA analogue output with 35.5 µA/g sensitivity. Its stainless-steel 316L housing, IP67 protection and 10 m screened PUR cable provide robust industrial installation. The sensor is designed for connection to external VSE vibration diagnostic electronics and supports drag-chain installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA205 provides a ±150 g measurement range for higher-vibration applications. Its 1–10,000 Hz frequency range supports detailed analysis of rotating machinery. The capacitive MEMS sensing principle provides single-axis measurement. A sensitivity of 35.5 µA/g provides the analogue response. This makes the VSA205 suitable for demanding machine-condition monitoring.
The VSA205 includes a 10 m screened PUR cable. The cable uses four 0.14 mm² conductors and includes a drain wire connected to the housing. The long cable allows the sensor to be installed away from the diagnostic electronics. PUR construction supports industrial cable routing. Drag-chain suitability provides additional installation flexibility.
The sensor uses a stainless-steel 316L housing and mounting-screw installation. The specified tightening torque is 5 Nm. IP67 protection supports industrial environmental conditions. Mechanical overload resistance is 500 g. The 309.7 g sensor construction provides a robust solution for high-range vibration measurement.

The ±150 g range gives the VSA205 substantial acceleration measurement capacity. The 10 kHz frequency range allows detection of high-frequency vibration components. This combination is useful for demanding machinery. The analogue output provides a continuous signal to the diagnostic system. The single-axis design provides a defined measurement direction.
The 10 m cable provides significant installation reach. This is useful when diagnostic electronics are installed away from the machine. The screened cable helps protect the analogue signal from electrical interference. PUR construction supports industrial cable handling. Drag-chain suitability allows use in suitable dynamic routing applications.
