About Cd-free contacts
We have introduced Cadmium free type
products to reduce Environmental
Hazardous Substances.
(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.)
Please replace parts containing
Cadmium with Cadmium-free products
and evaluate them with your actual
application before use because the life of
a relay depends on the contact material
and load.

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.
