Hi Tonyx,

For the displacement sensor, you can use a combination of a magnet and a linear Hall-effect sensor like the DRV5056. Two common magnet to sensor configurations are the head-on and slide-by configurations, which are described in the following documents:

In addition, the following tool allows you to experiment with different magnet types and configurations to find a suitable magnet for your application: Magnetic Sensing Proximity Tool

Can you tell me what the displacement sensor would be used for?

Thank you,

Mekre
