The IFM VSA007 is a single-axis MEMS acceleration sensor designed for vibration detection. It measures -25 to +25 g over a 1–6,000 Hz frequency range. The sensor provides a 0–10 mA analogue output and uses a 1/4"-28 UNF mounting thread. Its stainless-steel 316L housing and IP67/IP68/IP69K protection provide robust industrial performance. The sensor is a phase-out article with VSA001 identified by IFM as the alternative article.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA007 uses capacitive MEMS technology for single-axis vibration measurement. Its ±25 g range provides a defined acceleration measurement window. The 1–6,000 Hz frequency range supports vibration detection across a broad machine spectrum. Its 142 µA/g sensitivity provides an analogue output proportional to measured acceleration. This makes the sensor suitable for machine-condition monitoring.
The sensor uses a 1/4"-28 UNF mounting thread. Its stainless-steel 316L housing provides mechanical durability. The supplied conical washer supports proper installation. The specified tightening torque is 8 Nm. This provides a secure mechanical connection to the monitored machine.
The sensor is designed for connection to external VSE diagnostic electronics. Its IP67/IP68/IP69K protection provides multiple levels of environmental protection. The operating temperature range is suitable for industrial machinery. Reverse-polarity protection helps protect the electrical circuit. These features support reliable vibration detection in demanding installations.

The 1/4"-28 UNF mounting thread provides compatibility with suitable machine mounting points. The conical washer supports proper sensor seating. Stainless steel provides a durable mechanical interface. The 8 Nm tightening torque provides the specified installation condition. This makes the sensor practical for machine vibration measurement.
IFM identifies the VSA007 as a phase-out article and lists VSA001 as an alternative. The replacement should therefore be evaluated against the required measurement range and mechanical interface. The original VSA007 remains a defined vibration-sensing component. Its specifications support established VSE installations. This is useful for maintaining existing vibration-monitoring systems.
