■ Precautions
● Please refer to “PCB Relays Common Precautions” for correct use.
Correct Use
PCB Power Relay
● Mounting
? When mounting a number of relays on
a PCB, be sure to provide a minimum
mounting space of 5 mm between the
two juxtaposed relays as shown
Refer to the following table for
examples of positive-lock connectors
made by AMP. Contact the
manufacturer directly for details on
connectors including availability.
Therefore, do not use the Relay in a
strong magnetic field environment.

● Handling
? 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.
Also, do not insert terminals at an
angle, or insert/remove multiple
terminals at the same time. Be sure to
insert and remove terminals carefully
one at a time.

air-feeding.
● Minimum Pulse Width of Double-
winding Latching Relays
? The minimum pulse width shown in
the table of characteristics are values
measured under conditions of ambient
temperature at 23°C with rated
operating voltage imposed on coil. The
Relay may not provide a satisfactory
performance as its holding ability
decreases depending on the operating
circuit conditions and ambient
temperature, or decreases due to
degradation over time.
In actual operation, impose to the coil
a rated operating voltage with a pulse
width that is suitable to the actual load,
and reset the setting at least once a
hard magnetic material, and the rate
of degradation over time depends on
the ambient environment (e.g.,
temperature, humidity, vibration, and
presence or absence of external
magnetic fields).Perform maintenance
at least once a year by resetting,
applying the rated voltage again, and
then setting.
● Wiring High Capacity (-E) Models
? High-capacity models (-E) have a
structure that connects two terminals
from one contact.
When designing the circuit, use both
terminals.
If you use only one terminal, the relay
may be unable to satisfy specified
performance.
year, to correspond to the degradation
over time.
? When using the Relay in a strong
magnetic field environment, the
magnetic body may be demagnetized
due to the influence of environment,
causing the Relay to malfunction.
