The IFM VSA001 is a single-axis MEMS acceleration sensor for vibration detection. It measures vibration from -25 to +25 g across a 1–6,000 Hz frequency range. The sensor provides a 0–10 mA analogue output with a maximum load of 300 Ω. Its stainless-steel housing uses an M8 × 1.25 mounting arrangement and operates from 7.2 to 10.8 V DC. IP67/IP68/IP69K protection makes it suitable for demanding machine-condition monitoring environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA001 uses a capacitive MEMS sensing principle. Its ±25 g range provides vibration measurement for machinery and equipment. The 1–6,000 Hz frequency range covers a broad range of mechanical vibration behaviour. The sensor provides one measurement axis. This makes it suitable for single-axis machine vibration monitoring.
The sensor provides a 0–10 mA analogue current output. The maximum output load is 300 Ω. This output can be connected to compatible IFM vibration diagnostic electronics. The sensor operates from a low-voltage 7.2–10.8 V DC supply. This arrangement provides a direct analogue representation of measured acceleration.
The VSA001 uses a stainless-steel 316L/1.4404 housing. Its M8 × 1.25 mounting interface provides secure mechanical installation. The sensor is rated IP67, IP68 and IP69K. It operates from -30 to 125°C, with cULus operation below 85°C. The supplied conical washer supports proper mechanical mounting.

The 6,000 Hz upper frequency limit allows the VSA001 to detect relatively high-frequency vibration components. The ±25 g range provides a useful measurement window for industrial machinery. The capacitive MEMS principle enables compact sensor construction. Single-axis measurement provides a defined measurement direction. This makes the sensor suitable for targeted vibration analysis.
The 316L stainless-steel housing provides a durable mechanical structure. IP67/IP68/IP69K protection supports harsh industrial environments. The M8 mounting thread provides a secure connection to the machine. The supplied conical washer supports proper mounting. The sensor is designed for connection to external IFM vibration diagnostic electronics.
