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.

Note: All specifications are based on the condition of 25°C 77°F, 50% R.H. unless
otherwise specified.
#1 This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the
actual load.
