What This 2-Position Header Does in a Harness
The 2825274-2: The 13 A per contact rating at 600 V means this header can handle a single power pair or a signal pair in a 24-18 AWG range without exceeding the contact temperature rise.
Current, Temperature, and Material Limits
For applications that see frequent disconnect (field-service access panels), a gold-plated sibling in the VAL-U-LOK family would extend cycle life. The UL94 V-0 flammability rating and glow wire compliance are mandatory for automotive interior and household appliance enclosures where the connector sits inside a plastic housing that must self-extinguish within 10 seconds. The 600 V rating is the dielectric withstand between adjacent circuits — in a 2-position part, that's the voltage stress across the two pins, not a line-to-ground rating.
Mating Half and PCB Footprint
The 0.165" (4.20 mm) row spacing and 0.138" (3.50 mm) post length set the PCB footprint: the through-hole pattern is a 2×1 grid with 4.20 mm between rows. The board lock adds two additional through-hole anchors outside the signal pin pattern — confirm the PCB layout accommodates these extra holes before committing the BOM.
