Note 1. Tighten the connector by hand to a torque of 0.39 to 0.49 N·m. If the con-
nector is not tightened sufficiently, it will not provide the expected degree
of protection and may become loose due to vibration. Do not use pliers or
other tools to tighten the connectors, because these tools may damage the
connectors.
2. The OMRON S8@@ Power Supply Unit is recommended for the I/O power
supply. The load short-circuit detection function uses the transistor's ther-
mal shutdown, so when a Power Supply Unit with a low-capacity rating or
instantaneous shutoff overcurrent protection is used, the load short-circuit
may not be detected. Always use a Power Supply Unit with a rating of 50
W or higher if it uses dropping overcurrent protection characteristic. Always
use a Power Supply Unit with a rating of 150 W or higher if it uses intermit-
tent overcurrent protection. The current limiter will protect the transistor
even if short-circuit detection is disabled.
Connect the I/O wiring to the Environment-resistive Terminal with the XS2-
series Round Waterproof Connectors listed in the following table.
Cable with connector on one end (male plug)
Cable with connectors on both ends (socket and plug)
Connector plug assembly (male)
(Crimp-connector or solder type)
Sensors that are pre-wired with a connector can be connected directly.
Refer to the catalog or manual for details on the device's pin arrangements
before connecting any device.
