The 1766709 is a green, 6-position PCB header from the GMSTBVA 2,5/..-G product range, designed for vertical connection on a printed circuit board. It features a nominal current rating of 12 A and a rated voltage of 630 V (III/2), with a 7.5 mm pitch and a nominal cross-section of 2.5 mm². The header is configured for wave soldering with a linear pin layout, 3.9 mm solder pins, and tin-plated pin contacts. As part of the COMBICON MSTB 2,5 plug-in system, its vertical orientation enables multi-row arrangements, and the larger pitch accommodates applications with increased voltage requirements, offering flexibility in device design.
