Product details

Right-angle header for board-edge signal taps

ROHS3 compliant, with a UL94 V-2 rated nylon housing. The V-2 rating is acceptable for general-purpose equipment inside an enclosure; if your application requires V-0, verify the housing material against your safety standard.

The header is shrouded on one wall, providing keying against reverse mating. It accepts a Molex KK254 crimp receptacle housing (such as the 50-57-9403 or similar 3-circuit housing) with the matching 2.54 mm pitch terminals.
