Famaritana fohy:

Ireo "switch proximity" magnetika dia ahitana ny "switch proximity" eddy current, "switch proximity capacitive", "switch proximity Hall", "switch proximity photoelectric", "switch proximity pyroelectric", "switch magnetic TCK" ary ireo "switch proximity" hafa. Satria azo atao araka ny fitsipika sy fomba samihafa ny "sensor displacement", ary samy manana ny fomba "fahitana" ny zavatra ny sensor displacement tsirairay, dia misy ireto "switch proximity" mahazatra ireto: "switch proximity eddy current". Indraindray antsoina hoe "switch proximity inductive" ity "switch". Ny fampiasana zavatra mitondra herinaratra akaiky azy dia afaka miteraka sehatra elektromagnetika.
