Edgeboard Connectors Procurement Notes
Verify the specific suffix 'MS' indicates ring bellows contacts and wire wrap termination, distinct from other variants like 'UN' or 'KS'. Confirm RoHS3 compliance and MSL Level 1 status. Ensure the required card thickness matches the 0.062-inch specification. Check for side-mount flange requirements during mechanical design.
Edgeboard Connectors Selection Notes
Select this model when a 0.156-inch pitch dual-edge connector with wire wrap termination is required. Compare against RMM25DRUN for solder tail options or RMC25DRES for different pitch needs. Consider the PPS material for thermal stability. Verify that the side-mount opening aligns with chassis mounting constraints.
Edgeboard Connectors Part Context
This component belongs to the RMM25 series of edgecard connectors from Sullins Connector Solutions. The series offers various termination styles and contact types.
