About Cd-free contacts
We have introduced cadmium-free type 
products to reduce environmentally 
hazardous substances. Please replace 
parts that contain cadmium with Cd-free 
products. Evaluate them with your actual 
application before use because the life of 
a relay depends on the contact material 
and load.
Note: Add the suffix “F” to the part 
number for the 1 Form A 1 Form B 
contact type. The 1 Form A and 2 Form A 
contact types were originally Cd-free, 
hence the suffix “F” is not required.

#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.
