The IFM VSA002 is a single-axis MEMS acceleration sensor designed for vibration detection. It measures -25 to +25 g across a 1–10,000 Hz frequency range. The sensor provides a 0–10 mA analogue output and operates from 7.2 to 10.8 V DC. It uses a stainless-steel housing with IP67 protection and an M16 × 1.5 mounting arrangement. A 0.76 m screened PUR cable with M12 connector provides the electrical connection.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA002 covers a frequency range up to 10,000 Hz. Its ±25 g measuring range allows detection of a broad range of vibration amplitudes. The capacitive MEMS sensing element provides single-axis acceleration measurement. This makes it suitable for detailed vibration monitoring of rotating machinery. The sensor is designed for connection to external IFM VSE diagnostic electronics.
The 0–10 mA analogue output provides the vibration signal to compatible diagnostic equipment. The maximum load is 300 Ω. The sensor requires 7.2–10.8 V DC and consumes less than 15 mA. Reverse-polarity protection helps protect the sensor during electrical installation. This makes the VSA002 suitable for integrated machine-monitoring systems.
The VSA002 uses a stainless-steel 316L/1.4404 housing. Its M16 × 1.5 mounting interface provides secure installation on machinery. The sensor has IP67 protection and operates from -30 to 85°C. The 0.76 m screened PUR cable provides a compact prewired connection. Its 87.5 g construction is suitable for industrial machine installation.

The 10 kHz frequency range allows the VSA002 to detect higher-frequency vibration components. This makes it suitable for detailed machinery analysis. The ±25 g range provides a useful dynamic measurement window. The MEMS sensing element provides compact single-axis measurement. The analogue output allows the sensor to interface with diagnostic electronics.
The integrated 0.76 m PUR cable provides convenient connection to the monitoring system. Its screened construction helps support signal integrity in industrial environments. The M12 connector provides a standard connection interface. The sensor can be mechanically fixed using its M16 × 1.5 mounting. This provides a practical combination of mechanical and electrical installation features.
