Available Area

Japan, the US, Canada, China, Taiwan, South Korea, and Europe*1

This item is not available in Mexico due to the Radio Act.
Please check the "Available Area" of each product page.
*1: Only the black (-BK) model can be used in Europe.


  • The built-in motor rotates the feed screw, grasping the current position via the encoder and stopping at the target position. Positioning is automated with the feed screw.

EPU-220Wireless Positioning Units

  • For EPU-220 control, a dedicated transceiver (sold separately) is required. The required transceiver differs depending on the host/connection method.
    EPC-200-CCEPC-200-CC----PLC control (CC-Link connection) *1
    EPC-210-EIPEPC-210-EIP----PLC control (EtherNet/IPTM connection)*1

*1: Control with a PC is also possible.

  • One dedicated transceiver can control up to 32 units at the same time. Signals from the transceiver to each unit are transmitted wirelessly, with no troublesome cable wiring required.*2

*2: Wired connection is also possible. When connecting multiple units, the use of the separately sold repeater hub EORP-200 (EORP-200) enables easy wired connection and reduces wiring work.

  • Mounting can be completed simply by replacing the installed operation handle with EPU-220. Compared with the use of a combined handle and indicator, it is thinner and more compact.

EPU-220Wireless Positioning Units

  • IP65 dust-proof and waterproof structure. It can be used safely even in environments where it may be exposed to dust or water.
  • For initial setting and PC control, the dedicated software EPU-COM is required. The dedicated software is available free of charge. Please download from the NBK website.
  • The dedicated software function enables registration of up to 100 setups.
    EPC-200-CCEPC-210-EIP----Max. 100
  • Cable terminal specifications can be selected by the product code. When using the repeater hub EORP-200 (EORP-200), select the connector type.
    EPU-220-A----Discrete wire
