40-Position, 0.100" Pitch Right-Angle Receptacle
The 2-535512-5: The mating face carries 30 µinch gold over nickel on phosphor bronze contacts. At this thickness the interface is rated for repeated mating cycles without oxide buildup — a practical fit for field-service or test-equipment boards where the connector sees dozens of mate-unmate events over its life.
Board Fit and Mating Half
The push-pull fastening type means the receptacle is retained by friction only; no secondary latch or screw lock. In a vibration environment, the fit relies on the header's pin retention and the board's solder joint. The contact finish on the post is tin-lead (50 µinch), which solders well with standard SnPb processes. Note the RoHS status: this part is RoHS non-compliant due to the lead content in the post finish — a consideration for assemblies that must meet RoHS directives.
