Easy-wire Connectors for Industrial Components
Easy-wire Connectors with
* 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
AWG28 (0.08 mm2) to AWG20 (0.5 mm2).
(External sheath diameter: 1.5 mm max.)
Note: These specifications are currently being promoted for
standardization by manufacturers of FA components and
connectors. Connector specifications are disclosed only
for the mating portions.
• No special tools are required, making wiring easier.
• Compact design assists in conserving space in equip-
ment and machines.

Assembly Instructions
Preparing the Cable
Align the cable with the guide
marked STRIP GAUGE on the
side of the Connector, strip 7 to
8 mm of the cable sheath, and
then twist the wires several
times.
Connecting the Cable to the Connector
1. Use a flat-blade screw-
driver to push down the
operating lever inside
the operation slot until
it locks.
2. Insert the wire fully to the back of the wire insertion hole. Make
sure that the cable sheath is inserted into the hole, and that the
end of the wire has passed through the contact section.
3. Insert the screwdriver into the
release slot, and gently pull
back the lever until a click is
heard by resetting the lever.
4. Make sure that the following operations
have been performed.
• Check that the operating lever is reset.
• Check that the procedure in step 2 has
been followed. (Pull gently on the cable
to make sure that there is resistance, in-
dicating that the Connectors are wired
correctly.)
Removing Cables from the
Connector
1. Press down on the operating lever to lock
the lever before removing the cable.
2. After removing the cable from the Con-
nector, always reset the operating lever,
except when rewiring the Connector. The
Connector can be rewired without reset-
ting the operating lever.

Safety Precautions
■General Precautions
• 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 Connec-
tors.
• Do notuse the Connectors if the lock lever is bent or broken. Do-
ing so may cause the Connector to become loose or the device
to malfunction.
• Before mounting Connectors to a PCB, make sure that the Con-
nectors 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 Con-
nectors 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
Wiring
• Insert one wire into each insertion hole. Inserting two or more
wires into a single hole may cause unexpected problems.
• Makesure that no power is being suppliedto a Connector before
wiring, inserting, or removing the Connector. Doing somay 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 op-
eration manual, making sure not to damage the wires.
• Do notuse 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 screw-
driver.
• Using other screwdrivers may cause damage to the adjacent
poles.
