* The [] in the Spacer model number stands for a letter in the range A to U. (Refer to the table in the following
   explanation about Spacers.)

End Caps

End Caps are used on the Switch Units at each end and allow all the Switch Units to be securely mounted to a panel. They come in pairs, one for the left and one for the right. 

Spacers

  • Spacers are used for creating extra space or gaps between the Switch Units and have the same dimensions as the Switch Units themselves.
  • There are also Spacers with engraved characters or symbols that can be used for indicating units, such as time and length. (Refer to the following table.) Consult your OMRON representative for details.
