18-position 2.5mm pitch header for wire-to-board power
The 1-2132415-8 is a vertical through-hole header from TE's Economy Power 2.5 series, with 18 positions loaded in a single row at 2.50mm pitch. It's rated 4.2A per contact at 250VAC, which puts it in the signal-to-light-power range — enough for a bank of industrial sensors or a lighting string, but not for a motor drive bus.
Contact plating and temperature range for industrial duty
That covers most indoor industrial enclosures and outdoor telecom cabinets, though the 105°C ceiling means it's not a fit for engine-bay or high-temp oven applications.
