Description of Standard Dimensions (1)

  • Lead wires: in the case of AWG28, lead wires conform to UL1061; in the case of AWG26, they conform to UL1007 and UL1430.
  • Apart from discrete wire input connection, we also offer input connection by FPC.
  • Please refer to the diagram for a standard front plate.
  • Where the gear is attached to the shaft by press fitting, the length of shaft should be selected such that the end of the shaft extends more than 0.5mm beyond the end face of the gear. This reduces problems with press fitting.
