ROFIN-SINAR Technologies 421-4 Printed Circuit Board

ROFIN-SINAR Technologies 421-4 Printed Circuit Board is a model-specific ROFIN-SINAR PCB identified by the 421-4 designation, with related identifiers 581421, 221321, 422-2B and 930099 that help confirm lineage and cross-reference within ROFIN-SINAR's catalog. The listing compiles these numbers to support inventory control and replacement planning. The listing note "PCB BOARD, Ag" signals a silver (Ag) finish or plating associated with the board, which can affect corrosion resistance and contact reliability in compatible assemblies. This 421-4 PCB serves as a compact electronic substrate intended for integration with ROFIN-SINAR devices and systems that require the 421-4 form factor and compatible interconnect topology, making it a specific option for replacement or refurbishment when sourcing exact model 421-4 boards is necessary. Because the information is limited to model, identifiers, and finish, buyers can verify compatibility by cross-referencing the part numbers and model designation against their ROFIN-SINAR inventory to ensure correct fit and connector compatibility before procurement.
