■Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
Correct Use
● Mounting
• Make sure that sufficient space is
provided between relays when
installing two or more relays side by
side to facilitate heat dissipation.
Insufficient heat dissipation may result
in the relay malfunctioning.
Pitch:
2.54 mm × 4 min.

● Quick-connect Terminal
Connections
• Do not pass current through the PCB
of the load contact terminals
(quick-connect terminals).
• The terminals are compatible with
Faston receptacle #187 and are
suitable for positive-lock mounting.
Use only Faston terminals with the
specified numbers. Select leads for
connecting Faston receptacles with
wire diameters that are within the
allowable range for the load current.
Do not apply excessive force to the
terminals when mounting or
dismounting the Faston receptacle.
Insert and remove terminals carefully
one at a time. Do not insert terminals
on an angle, or insert/remove multiple
terminals at the same time.
The following positive-lock connectors
made by AMP are recommended.
Contact the manufacturer directly for
details on connectors including
availability.

● Charged Terminals
• The section marked with dotted circles
(indicated by arrows) in the following
diagram includes the charged
terminals of the relay.
When the relay is mounted on a PCB,
make sure that there are no metal
patterns on the section of the PCB
facing the portion of the relay shaded
in the following diagram.

● Other Precautions
• The G5CA is a power relay designed
for applications switching power loads
such as heaters in electric household
appliances. Do not use the G5CA to
switch micro loads less than 100 mA,
such as in signal applications.
• Use fully sealed models if the relays
will require washing. Flux-protection
models may malfunction or the relay's
performance may be otherwise
adversely affected if cleaning fluid
enters the relay.
The numbers shown in parentheses are for
air-feeding.
• 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.
Note: Do not use this document to operate the Unit.
