    G'day,

    I am building a device and housing electronic circuits, sensors etc together with a 12VDC 5W motor, in a small abs appliance enclosure.

    The pressure sensor advises not being near a motor as it can shorten it's life. How can I shield expensive components that are sensitive to magnetic field created by the motor?

    Apart from damage to the sensor, do I also need to worry about interference from the motor?

    Thanks.

    Magnetic fields from a motor are generally only a problem for sensitive circuits carrying low voltage analog signals. If that's actally a problem then you will need to place those circuits in a magnetic shielded box inside the enclosure.

    No worries!

    Thats a relief, as I have minimal spare space.

    Also, I just found this site descrining how to shield a magnet http://www.coolmagnetman.com/magshield.htm from your promt giving me a basic understanding, so your post was good value!

    Thanks!
