Safety Precautions
Precautions for Correct Use
Do not use the product in any atmosphere or environment that
exceeds the ratings.
●Automatic Soldering
Automated Soldering Conditions (Jet Flow)
(1) Soldering temperature: 250 ± 5°C
(2) Continuous soldering time: within 5 ± 1 s
●Storage
Do not store the Connectors in locations subject to dust or high
humidity. Do not store the Connectors in locations close to sources of
gasses such ammonia gas or sulfide gas.
●Terminal Shapes
The terminals will deform if they are subjected to an excessive load,
which will in turn reduce solderability when mounting. Do not drop the
Connectors or handle them carelessly. Do not connect anything when
the Connectors are not mounted to a board. Doing so may deform the
terminals.
●Using an Automatic Solder Bath
Mask the mating portion with tape before you perform automatic
soldering to prevent flux or solder from entering the mating portion of
the Connector. Select and use a suitable masking tape.
●Application Precautions
• Confirm that there is no excessive misalignment or inclination in
the mating contact portion between the plug and socket before
mating the Connector. Make sure that the Connector is mated all
the way to the back. If the Connector is not mated all the way to the
back, contact reliability may be lost.
• Do not apply an extreme load during Connector insertion or
removal. The Connector may be damaged, and contact failure may
result. Twist the plug and socket as little as possible when mating
the Connector. Not doing so may deform the terminals or housing
or crack the housing.
• Do not insert a foreign object, such as tweezers, into the Connector
mating contact portion. Doing so may cause the plating to peel off
or deform the terminals.

• Application examples provided in this document are for reference only. In actual applications, confirm equipment functions and safety before using the product.
• Consult your OMRON representative before using the product under conditions which are not described in the manual or applying the product to nuclear control systems, railroad
systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, and other systems or equipment that may have a serious
influence on lives and property if used improperly. Make sure that the ratings and performance characteristics of the product provide a margin of safety for the system or
equipment, and be sure to provide the system or equipment with double safety mechanisms.
