Fa'amatalaga Pupuu:

O ki fa'amagnetisi e aofia ai ki fa'amagnetisi eddy current, ki capacitive proximity, ki Hall proximity, ki photoelectric proximity, ki pyroelectric proximity, ki TCK magnetic ma isi ki fa'amagnetisi.
Talu ai e mafai ona faia ni masini fa'ase'e e tusa ai ma mataupu fa'avae eseese ma metotia eseese, ma e eseese fo'i metotia "iloilo" a masini fa'ase'e mo mea faitino, o lo'o i ai nei suiga masani o le latalata: vortex
Suiga o le auala e tafe ai
O lenei ki e ta'ua i nisi taimi o le inductive proximity switch. O le fa'aaogaina o mea e tafe ai le eletise i tafatafa ane e mafai ona fa'atupuina ai se fanua eletise.
