The IFM VSA201 is a high-range single-axis MEMS acceleration sensor for industrial vibration detection. It measures -250 to +250 g across a 1–6,000 Hz frequency range. The sensor provides a 0–10 mA analogue output and uses an M8 × 1.25 mounting interface. Its 316L stainless-steel housing provides IP67/IP68/IP69K protection and high mechanical durability. An M12 A-coded connector provides the electrical interface to external VSE diagnostic electronics.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA201 provides a ±250 g vibration measurement range. This gives it a significantly higher acceleration range than the ±25 g VSA models. Its 1–6,000 Hz frequency range supports vibration detection across industrial machinery. The capacitive MEMS principle provides single-axis measurement. This makes the VSA201 suitable for high-vibration environments.
The sensor provides a 0–10 mA analogue output for external diagnostic electronics. It operates from 7.2–10.8 V DC. The M12 connector provides a defined interface for compatible connection cables. Reverse-polarity protection is included. This allows the sensor to operate as part of an IFM VSE vibration-monitoring system.
The VSA201 uses a cylindrical 316L stainless-steel housing. Its M8 × 1.25 mounting interface is tightened to 8 Nm. The sensor measures approximately Ø17 × 53 mm and weighs 49 g. IP67/IP68/IP69K protection provides strong environmental protection. The supplied conical washer supports proper mechanical installation.

The ±250 g range allows the VSA201 to measure substantially higher vibration amplitudes. This makes it suitable for machinery where lower-range accelerometers may not provide sufficient measurement capacity. The 6 kHz frequency range supports detailed vibration monitoring. Single-axis sensing provides a defined measurement direction. This makes the sensor useful for heavy industrial equipment.
The M8 × 1.25 interface provides secure machine mounting. Stainless steel 316L provides strong mechanical durability. The supplied conical washer supports correct installation. The 8 Nm tightening torque provides the specified mounting condition. IP67/IP68/IP69K protection supports industrial environmental exposure.
