The IFM VSA004 is a single-axis MEMS acceleration sensor for machine vibration detection. It measures -25 to +25 g over a 1–10,000 Hz frequency range. The sensor provides a 0–10 mA analogue output and uses a 3 m shielded halogen-free PUR cable. Its stainless-steel 316L housing and IP67 protection provide robust industrial construction. The sensor is designed for connection to external VSE vibration diagnostic electronics.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VSA004 uses a capacitive MEMS measurement principle. It provides one measurement axis with a ±25 g range. Its frequency range extends to 10,000 Hz for detailed vibration detection. The 142 µA/g sensitivity provides a defined analogue response. This makes it suitable for monitoring vibration behaviour in industrial machinery.
The sensor includes a 3 m shielded PUR cable. The cable is halogen-free and contains four 0.14 mm² conductors. The analogue output is 0–10 mA with a maximum load of 300 Ω. A drain wire is connected to the sensor housing. This arrangement provides a practical connection for external vibration diagnostic electronics.
The VSA004 uses a 316L stainless-steel housing and mounting screw. Its IP67 protection supports industrial environmental exposure. The operating temperature range is -20 to 80°C. The sensor is mechanically rated for 500 g overload and 50 g shock resistance. Drag-chain suitability allows use in suitable dynamic cable installations.

The 3 m cable provides useful reach between the machine and diagnostic electronics. The shielded construction supports reliable analogue signal transmission. Halogen-free PUR provides suitable industrial cable performance. The cable is designed for drag-chain use within the specified bending requirements. This makes the VSA004 useful for machinery where the diagnostic unit is located away from the sensor.
The stainless-steel housing provides a durable mechanical structure. The supplied M5 × 20 mm head-cap screw supports installation. A 5 Nm tightening torque provides the specified mounting condition. IP67 protection supports industrial environments. The sensor is therefore suitable for permanent machine vibration monitoring.
