NOTES
1. Coil operating power
Pure DC current should be applied to the
coil. The wav e 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. Cleaning
In automatic cleaning, cleaning with the
boiling method is recommended. A v oid ultrasonic cleaning which subject the relay
to high frequency vibrations. It may cause
the contacts to stick.
lt is recommended that a fluorinated hydrocarbon or other alcoholic solvent be
used.

4. Automatic insertion
To maintain the internal function of the relay, the chucking pressurre should not exceed the values below.
Chucking pressure in direction A:
9.8 N {1 kgf} or less
Chucking pressure in direction B:
9.8 N {1 kgf} or less
Chucking pressure in direction C:
4.9 N {500 gf} or less
Please chuck the portion.
Avoid chucking the center of the relay.
