2.00 mm pitch, 3 positions — single-row board-to-wire header
The 1-1971032-3 is a 3-position, single-row male header from TE's EV series, designed for board-to-cable/wire applications. The header is fully shrouded with 4 walls, protecting the square pins from damage during blind mating and preventing accidental shorting against adjacent components. A latch holder fastening type provides positive retention against cable pull and vibration — useful in mobile equipment or panels subject to shock.
Tin-plated contacts, 78.7 µinch — field-service duty
Both the mating and post contact finishes are tin, with a thickness of 78.7 µinch (2.00 µm). Tin-plated contacts are cost-effective for moderate mating-cycle applications — expect several dozen to low hundreds of cycles before wear-through. In a field-service connector that is cycled a few times per year, this plating grade delivers reliable performance over the product's service life without the cost premium of gold. The brass contact material with tin plating resists corrosion in non-aggressive atmospheres.
