The 3-position count is the BOM line match: a 3-circuit harness needs exactly this housing. The polarizing key prevents mis-mating with a non-keyed header, which is a practical safeguard on a production line where multiple SL-156 connectors share a harness bundle. Crimp termination means the socket contacts are attached to the wire before insertion into the housing. Typical TE part numbers for these contacts include the 770875 series (tin-plated) or 770876 series (gold-plated), depending on the current and cycle-life requirements of your application. The crimp terminals are inserted into the housing after wire termination; the locking ramp and housing geometry retain them.","metaTitle":"TE Connectivity 770849-3 SL-156 Receptacle, 3 Position","metaDescription":"TE Connectivity 770849-3 SL-156 receptacle, 3 positions, 0.156\" pitch, natural nylon housing, crimp termination, locking ramp.
