COMMENTS ABOUT Cd
FREE
We have introduced Cadmium free type
products to reduce the material which is
not good for our environment.
(The suffix “F” should be added to the
part number.)
(Note: The Suffix “F” is required only for
1 Form A 1 Form B contact type.
The 1 Form A and 2 Form A contact type
is originally Cadmium free, the suffix “F”
is not required.)
If you are still using Cadmium containing
parts, which don’t have “F” on the suffix
of the part number, please use Cadmium
free parts from now on. The life of the
Cadmium free products may be shorter
than the Cadmium containing parts
based on the load condition, so please
evaluate the Cadmium free parts with
your actual application before use.

FIXING AND REMOVAL METHOD
1. Match the direction of relay and socket.
3. Remove the relay, applying force in the
direction shown below.
2. Both ends of relays are fixed so surely
that the socket hooks on the top surface
of relays.
4. In case there is not enough space for
finger to pick relay up, use screw drivers
in the way shown below.
