The unshrouded push-pull design gives direct access to the square pins for probing or manual wiring, but leaves the contacts exposed — the mating receptacle needs to provide the alignment and polarization. The black UL94 V-0 rated insulator suits equipment enclosures that require a flammability rating. Overall contact length is 0.513\" (13.03 mm), with a 0.230\" (5.84 mm) mating section and a 0.183\" (4.65 mm) solder tail, which sets the board standoff and through-hole drill depth.","metaTitle":"Amphenol FCI BERGSTIK II 68031-121HLF, 21-pos 2.54mm Header","metaDescription":"68031-121HLF BERGSTIK II header: 21 circuits, 0.100\" pitch, 5 A, 110 V, unshrouded through-hole.
