Measurement: after the relay kept static by
applying a rated voltage, leave the relay at room
temperature of 20°C to 30°C, and high temperature
of 80°C ± 2°C respectively, to measure how the
keep-power varies with time.

● 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

below.

● 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.

Refer to the following table for

examples of positive-lock connectors

made by AMP. Contact the

manufacturer directly for details on

connectors including availability.

Note: The numbers shown in parentheses are for

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

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.

Therefore, do not use the Relay in a

strong magnetic field environment.

● Degradation over Time of Double­winding Latching Relays Holding
Ability

• If a double-winding latching Relay is

used left set for an extended period,

changes over time will degrade the

magnetic force, and the reduction in

holding ability may cause the set

status to be released. This is also

because of the properties of semi-

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.
