* Substitute “2A” or “2B” in place of “2C” for Form A or B respectively. Add suffix “E” to “2A” or “2B” or “2C” for silver tin oxide contacts. Add suffix “B” to
“2A” or “2B” or “2C” for silver nickel contacts. Add suffix “A” for gold plated contacts. Add suffix “F” for Class F version (DC coils only).
When suffix “E” is
specified for Epoxy Seal, refer to AZ “Relay Technical Notes” on AZ website - Product Resources. Consult factory for other PCB process conditions that may
apply.
