It does not. The mating contact is the SL-156 crimp socket (TE part number 640550-1 or equivalent), which must be crimped onto 18-24 AWG wire before insertion. Factor the terminal cost and the crimp tooling into the total line item, not just the housing price.","metaTitle":"TE Connectivity SL-156 647401-4","metaDescription":"TE Connectivity SL-156 4-position receptacle housing, 0.156\" pitch, natural nylon, locking ramp.
