Style is Board to Cable/Wire — a through-hole soldered header that mates with a crimp-socket receptacle. The 4-wall shroud and latch lock keep the pair engaged under moderate vibration, typical for power supplies, appliances, and industrial control panels. ## Pitch, Pinout, and Mating Half Mating pitch is 0.165 inch (4.20 mm) and row spacing is the same 4.20 mm. The contact mating length is 0.220 inch (5.59 mm), post length 0.210 inch (5.33 mm) for through-hole soldering. All 4 positions are loaded. Mates with MR series crimp-socket housings that accept 20-24 AWG wire.","metaTitle":"640499-3 TE Connectivity MR Header, 4 Pos, 4.20 mm","metaDescription":"640499-3 TE Connectivity AMP MR series header, 4 circuits, 4.20 mm pitch, 6 A, 250 VAC, tin contacts, latch lock, UL94 V-0, active.
