A set of three magnetic mounts can be supplied to provide a simple solution for mounting the GridKey MCUs on metal panels without the need to drill holes in the panels. The mounts use strong Neodymium pot magnets with a countersunk hole on the magnetic face. The magnetism is concentrated on one face to provide the maximum holding force. The mounts come kitted with screws, nylock nuts and washers as required to be fitted to the MCU.
