Right-Angle Board Mount and Mating Half
The 640455-7: The single-wall shroud protects the pins from bending during insertion but leaves the top of the contact row exposed — it's not a fully enclosed header, so take care during handling to avoid stubbing pins against the receptacle shell.
Current, Voltage, and Temperature Range
At 250VAC the voltage rating covers typical signal and low-power distribution inside equipment.
Tin Contacts and Mating Cycle Expectation
In a field-service product cycled quarterly, that is roughly six years of service before fretting corrosion may increase contact resistance. The square male pins are copper alloy, 0.295" (7.49mm) mating length, which provides enough wipe to clear debris during insertion. The solder post length is 0.140" (3.56mm), suitable for standard 1.6mm-thick PCBs.
