■Precautions

●Please refer to “PCB Relays Common Precautions” for correct use.

●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-

• 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 Double-

• 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.
