To mate the Connectors, align the mating marks on the Plug
and Socket (see following figure), insert the Connectors
completely, and tighten the lock nut, being careful not to
damage the threads.

XS3
Safety Precautions
Do not use the product in atmospheres or environments that exceed product ratings.
Connections
The XS3 and XS2 Sensor I/O Connectors cannot be
connected to each other.
You cannot mate Connectors that have a different number
of poles.
When using Sensors with Connectors or Limit Switches,
use the Sensor I/O Connectors specified in the catalog.
Do not connect M8 screw-on models and S8 snap-in
models together, otherwise the proper degree of protection
of the Connectors will not be maintained.
Connector Connection and Disconnection
Before connecting or disconnecting Connectors, make sure
that no power is being supplied to the Connectors.
When connecting or disconnecting Connectors, be sure to
hold the Connectors by hand. Do not disconnect the
Connectors by pulling the cable.
Do not touch the mating surface of the connectors with wet
hands. If there is any water on the Connector or near the
Connector, be sure to wipe off the water before connecting
or disconnecting the Connector, otherwise the Connector
may short-circuit internally or not ensure good insulation.
Make sure that mating section of any Connector is free of
metal dust or power.
Do not use pliers to tighten mounting the thread bracket,
otherwise the thread bracket may be damaged. Be sure to
tighten each thread bracket by hand within a torque of
0.2 N·m. If the thread bracket is not tightened securely, the
Connector may not maintain its proper degree of protection
or the thread bracket may fall off due to vibration.
When you tighten or loosen a thread bracket, hold onto only
the thread bracket.
If you hold onto the cover or cable, excessive rotational
force will be applied to the Connector and may damage it.
Fully insert S8 snap-in models until the Connectors are
hidden by the metal casing of the opposite parts,
otherwise the Connectors will not maintain their proper
degree of protection or the thread brackets may become
loose due to vibration.
Degree of Protection
Do not impose external force continuously on the joints of
pin blocks and covers, otherwise the Connectors may not
keep its proper degree of protection (i.e., IP67).
Connectors are not fully watertight. Do not use them
underwater.
The Connectors are not oil-resistant. Do not use them
where they would be subject to oil.
If Connectors are used in places with vibration or shock,
secure the mating section of each Connector, otherwise the
Connectors may be disconnected or fail to maintain their
proper degree of protection.
Connectors are of resin mold construction. Do not impose
excessive force on them.
Storage
Do not store Connectors for long periods of time in the
following locations
Locations subject to dust or high humidity
Locations subject to ammonia gas or sulfide gas
Setup
Do not make any cable bends near the base of the Unit.
Any bends made must have a minimum radius of 36 mm.
