Two elements (phase A/B, phase Za/Zb) are packed in a package.A holder for bias magnet is also included.

The DIP package shall be aligned so that the rotational direction of the gear is normal to the longitudinal direction of the DIP package. In other words, the lines connecting the rotational direction of the gear and two elements shall be normal to each other. A space for a tooth on either element (shown in the figure at the right) shall be detected as the phase Z.

• (※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) = mp is obtained. (Where, m represents a gear module, and p indicates the circular constant.
• (※2)Package size does not include the leads.
• (※3)This represents the output terminal voltage when 5 V is applied to both ends of SMRE in non-magnetic field.
• (※4)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))
