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 magnetika TCK" ary "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 "switch proximity" mahazatra maromaro: "switch proximity eddy current".
