A range of shallow, limpet type, gripping magnets using ferritemagnet material set in mild steel shells. Magnetic field depths are in-between those of cast alloy pot magnets and magnets. Ideal for use as ""bases"" to machine tool accessories and industrial light fittings, where temperatures do not exceed a maximum of 80° C. A deep cylindrical permanent magnet assembled concentrically in a steel pot. These magnets are primarily for gripping applications and can be used to construct positioning jigs and soldering fixtures.
