내용에 따르면
One important quality of the switch is its sensitivity, the amount of magnetic field necessary to actuate it. Sensitivity is measured in units of Ampere-turns, corresponding to the current in a coil multiplied by the number of turns. Typical pull-in sensitivities for commercial devices are in the 10 to 60 AT range. The lower the AT, the more sensitive the reed switch. Also, smaller reed switches, which have smaller parts, are more sensitive to magnetic fields, so the smaller the reed switch's glass envelope is, the more sensitive it is.

스펙을 보면 같은제품같던데 무슨차이가 있나요?? 다른상품의 답변을 보니 숫자가 높을수록 감도가 낮아진다고 하던데 그러면 10~15가 감도가 가장 높은것인가요?
