The IFM VSA204 is a single-axis MEMS acceleration sensor for machine vibration detection. It provides a -150 to +150 g measuring range over 1–10,000 Hz. The sensor provides a 0–10 mA analogue output and uses a screened cable for external VSE diagnostic electronics. Its stainless-steel 316L housing provides robust industrial construction and IP67 protection. The VSA204 is a phase-out article with a listed discontinuation date of 31 March 2026 and VSA201 as the alternative article.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA204 provides a ±150 g measurement range. Its 1–10,000 Hz frequency range allows detection of both lower and higher-frequency vibration components. The capacitive MEMS principle provides single-axis acceleration measurement. The 35.5 µA/g sensitivity provides the analogue response required by compatible diagnostic electronics. This makes the sensor suitable for industrial vibration monitoring.
The VSA204 is designed for connection to external VSE diagnostic electronics. It provides a 0–10 mA analogue output with a maximum 300 Ω load. The sensor operates from 7.2–10.8 V DC and consumes less than 15 mA. Reverse-polarity protection is included. This enables integration into established IFM vibration-monitoring systems.
The sensor uses stainless-steel 316L construction and a mounting-screw installation. It provides IP67 protection and supports drag-chain cable routing. The operating temperature range is -20 to 80°C. Mechanical overload resistance is 500 g. These features provide durable operation in industrial machine environments.

The ±150 g range provides substantial measurement capacity for industrial vibration applications. The 10 kHz frequency range supports detailed vibration analysis. The analogue output allows the sensor to communicate with external diagnostic electronics. This makes it useful for machines where vibration amplitude and frequency both need monitoring. The single-axis configuration provides focused measurement.
The VSA204 is identified by IFM as a phase-out article. IFM lists 31 March 2026 as the discontinuation date and VSA201 as the alternative article. Replacement selection should account for the different technical specifications and mounting requirements. Existing VSA204 installations can therefore be reviewed for suitable replacement planning. This is important for maintaining established vibration-monitoring systems.
