2. 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:
4.9 N {500gf} 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
Avoid chucking the center of the relay.
In addition, excessive chucking pressure
to the pinpoint of the relay should be
avoided.
For general cautions for use,
please refer to the “Cautions for
use of Signal Relays” or “General
Application Guidelines”.
