Abstract
The invention relates to a linear sensor, comprising a sleeve, a pin which comprises a permanent magnet and is linearly displaceably supported in the sleeve, and a magnetic field sensor which is fastened to the sleeve and used to detect a displacement of the permanent magnet, characterized in that the pin is guided by way of a substantially cylindrical guide and has a magnet or pin holder.
Claims20
A linear sensor comprising:
- a sleeve;
- a pin comprising a permanent magnet where the pin is linearly displaceably supported in the sleeve and guided by way of a substantially cylindrical guide, the pin including a contact surface abuttable against a measurement object;
- a magnetic field sensor fastened on the sleeve and configured to detect a displacement of the permanent magnet;
- and
- a pin holder rigidly connectable at a distal end to the measurement object and at a proximal end resiliently biased against the pin configured to resiliently bias the contact surface against the measurement object.
