Geared Limit Switch


  • – Two types of geared limit switches are available: the standard ME type, and S type without a terminal block.
  • – The stop position can be set at one touch of a large button. The reproducibility error is ±10º to the input rotation angle.
  • – Due to the unique and rational structure, the geared limit switch works reliably, has superior durability, and realizes smooth rotation.
  • – Adopting the enclosed construction, the geared limit switches are compact and easy to install.
