Request Information
The LVP-25-Z20 sensors are used for monitoring the clamping position in machine tools. These inductive sensors are integrated in the release device and directly measure the clamping stroke of the drawbar onto which the target ring is glued. Due to their extremely compact design, these sensors are used for different types of tools while providing high-precision and continuous monitoring. No adjustment is necessary when changing the tool.

Additional Information

N/A The LVP-25-Z20 sensors are designed for monitoring the clamping position in machine tools.
The cylindrical sensors are integrated into the release device and detect the clamping stroke of the drawbar.
The measuring object is a ring which is glued onto the drawbar. The sensors can be universally used for different types of tools due to their extremely compact sensor design. The sensors provide an analog signal according to the stroke motion of the drawbar when clamping the tool. Consequently, continuous monitoring is possible without the switching point having to be set mechanically.
The miniature sensor controller can either be accommodated at the point of measurement or in the control cabinet. Thanks to their high accuracy, the sensors contribute significantly to meeting the ever increasing requirements for precision and availability of machine tools.
