ʻO nā kuapo kokoke Magnetic e komo pū me nā kuapo kokoke eddy current, nā kuapo kokoke capacitive, nā kuapo kokoke Hall, nā kuapo kokoke photoelectric, nā kuapo kokoke pyroelectric, nā kuapo magnetic TCK a me nā kuapo kokoke ʻē aʻe. No ka mea hiki ke hana ʻia nā sensor neʻe e like me nā loina like ʻole a me nā ʻano hana like ʻole, a he ʻokoʻa nā ʻano "ʻike" like ʻole o nā sensor neʻe no ka hoʻomaha kino, aia nā kuapo kokoke maʻamau: nā kuapo kokoke kahe pulu. Ua kapa ʻia kēia kuapo i kekahi manawa he kuapo kokoke inductive. ʻO ka hoʻohana ʻana i nā mea conductive kokoke i kēia hiki ke hoʻoulu i kahi kahua electromagnetic.
