double amplitude of 2 mm
About Cd-free contacts
We have introduced cadmium-free type
products to reduce environmentally
hazardous substances. Please replace
parts containing cadmium with Cd-free
products and evaluate them with your
actual application before use because
the life of a relay depends on the contact
material and load.
Contacts Coil (polarized) (at 25°C 77°F)
#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.
