Easy-wire Connectors for Industrial Components

XN2 Easy-wire Connectors for Industrial Components

Easy-wire Connectors with e-CON * Specifications; Ideal for Connecting Sensors.

  • Use industry-proven spring clamps for wiring.
  • No special tools required for easy wiring.
  • Rewiring (repairing) is possible.
  • Each Connector accepts any wire size from stranded wire AWG28 (0.08 mm2) to AWG20 (0.5 mm2).
    (External sheath diameter: 1.5 mm max.)
  • With the simple tool Jig, assembly can be completed for 4 wires simultaneously, is available.

Note: *E-con specifications are currently being promoted for standardization by manufacturers of FA components and connectors. Connector specifications are disclosed only for the mating portions.

Precautions for Safe Use

· Do not pull on the Connectors or cables. Doing so may cause damage to the Connectors or cause the cables to disconnect.
· Install the Connectors in a location where they will not be stepped on, to prevent disconnection of the cables or damage to the Connectors. If the Connectors have to be installed in such a location, use a protective cover.
·Make sure that the Connectors are mated in the correct direction. Mating the Connectors incorrectly will damage to the Connectors.
· Do not use the Connectors if the lock lever is bent or broken. Doing so may cause the Connector to become loose or the device to malfunction.
· Before mounting Connectors to a PCB, make sure that the Connectors are positioned in the correct direction.
· Before bending a cable to connect it to a Connector, check the bending specifications of the cable to be used.
· Do not exceed the rated current of the cable. Always check the rated current of each cable to be used.
· Do not use pliers or other tools to remove the Connectors.
· Hold the Connectors firmly by hand when handling them. Do not use excessive force to push the Connectors. Forcing the Connectors may result in injury.
· These Connectors do not resist water. Do not use Connectors in places where water or oil may be sprayed onto the Connectors.

Precautions for Correct Use


·Insert one wire into each insertion hole. Inserting two or more wires into a single hole may cause unexpected problems.
·Make sure that no power is being supplied to a Connector before wiring, inserting, or removing the Connector. Doing so may result in electric shock.
·Follow the wiring diagrams for the device being used when wiring the cables.
·Strip the cables according to the instructions in the applicable operation manual, making sure not to damage the wires.
·Do not use a screwdriver with a tip larger than the specified width when wiring the Connectors.
·Make sure short-circuits are not created, e.g., by protruding wires.

Inserting and Removing Connectors

·When connecting or disconnecting Connectors, always hold the case of the Connector.
·When mating Connectors, insert the Connector fully into the back of the socket, and then make sure that the Connector will not become loose by lightly pulling it in the opposite direction.

Recommended Screwdriver

·Use a flat-blade screwdriver with a tip of 2 mm max. Do not use screwdrivers that gradually widen towards the base of the screwdriver.
·Using other screwdrivers may cause damage to the adjacent poles.
