We consider the elastic interaction with matter of the light neutral fermion that arises as a natural candidate for dark matter in an extension of the minimal supersymmetric standard model. We particularly address its detectability in proposed cryogenic detectors and find that the rates to be expected are O(1)/kg day, if the particle's mass, Mx, is in the range Mx≈5-20 GeV. These rates are within reach of cryogenic detectors, and the mass range is not excluded at present by the experiments at LEP.
