The 0.100" (2.54 mm) pitch on both rows and between rows matches the standard 0.100" grid, so the footprint lines up with any common 2.54 mm female socket strip. All 70 positions are loaded — no skipped pins to track on the BOM. The 5 A figure is per-contact at a standard 25 °C ambient; derate as the cabinet temperature climbs. Overall contact length is 0.990" (25.15 mm), with a 0.770" (19.56 mm) mating section that engages fully with a standard 0.230" female socket.
Unshrouded means no plastic wall around the pins — the 87052-470HLF mates with any standard 0.100" pitch female header or socket strip that accepts 0.025" square pins. The 0.100" (2.54 mm) row spacing matches the pitch, so the 70 pins occupy a 35 x 2 grid that fits a 0.100"-grid prototype board or a custom PCB land pattern.
