1.Coil operating power
Pure DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. The nominal operating voltage should be applied to the coil for more than 10 ms to set/reset the latching type relay.
2.Coil connection
When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction.
3.External magnetic field
Since signal relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition.
4.Packing style
1.The relay is packed in a tube with the relay orientation mark on the left side, as shown in the figure below.

5.Automatic insertion
To maintain the internal function of the relay, the chucking pressure should not exceed the values below.
Chucking pressure in the direction A: 9.8 N {1 kgf} or less
Chucking pressure in the direction B: 9.8 N {1 kgf} or less
Chucking pressure in the direction C: 9.8 N {1 kgf} or less
(Please chuck the portion. Avoid chucking the center of the relay. In addition, excessive chucking pressure to the pinpoint of the relay should be avoided.)
6.M.B.B. contact relays
A small OFF time may be generated by the contact bounce during contact switching. Check the actual circuit carefully. If the relay is dropped accidentally, check the appearance and characteristics including M.B.B. time before use.

7.Others
If in error the relay has been dropped, the appearance and characteristics should be checked before use without fail.
The cycle lifetime is defined under the standard test condition specified in the JIS* C 5442-1986 standard (temperature 15°C to 35°C 59°F to 95°F, humidity 25% to 85%). Check this with the real device as it is affected by coil driving circuit, load type, activation frequency, activation phase, ambient conditions, and other factors.
