• (*1)The figure represents the pitch of the gear to be detected. If the gear pitch (crest-to-crest) is assumed as p, p (mm) = mπ is obtained. (Where, m represents a gear module, and π indicates the circular constant.)
• (*2)This presents the output terminal voltage when 5 V is applied to both ends of SMRE in non-magnetic field.
• (*3)This represents the change (rate) of the resistance value when a magnetic field is applied. R(B) and R(0) are defined as follows:
  R(B): Resistance value at the magnetic field B = 0.45(T),
  R(0): Resistance value at the magnetic field B = 0(T)
  ΔRin/Rin = (Rin(B) - Rin(0))/Rin(0)), ΔRout/Rout = (Rout(B) - Rout(0))/Rout(0))
