4. When using, please be aware that
the a contact and b contact sides of
1 Form A 1 Form B type may go on
simultaneously at operate time and
release time.
Since DK relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
2. Soldering should be done under the
following conditions:
1) Preheating: Within 120

FIXING AND REMOVAL METHOD
1. Match the direction of relay and socket.
3. Remove the rela
y
,
a
pplying force in the
direction shown below.
4. In case there is not enough space to
grasp relay with fingers, use screwdrivers
in the way shown below.
2. Both ends of the relay are to be
secured firmly so that the socket hooks
on the top surface of the rela
y
.
Notes: 1. Exercise care when removing relays. If
greater than necessary force is applied at
the socket hooks, deformation may alter the
dimensions so that the hook will no longer
catch, and other damage may also occur.
2. It is hazardous to use IC chip sockets.
