This housing ships empty. The mating crimp sockets (female contacts) must be ordered separately — a detail that trips up first-time buyers who expect a complete connector. The SL-156 series uses standard crimp terminals; verify the wire gauge range and plating (tin vs. gold) against your application's current and cycle-life requirements before placing the full order. The polyamide material carries a natural (unpigmented) colour, typical of standard-grade nylon used in non-UV-exposed internal connections.","metaTitle":"TE Connectivity 1-770849-1 SL-156 Receptacle Housing, 11 Pos","metaDescription":"TE Connectivity 1-770849-1 SL-156 receptacle housing, 11 positions, 0.156\" pitch, natural nylon, locking ramp, polarizing key.

The exact terminal part number depends on your wire gauge and plating preference — tin for general-purpose, gold for higher mating-cycle applications. Confirm the terminal against the SL-156 crimp specification before ordering."},{"question":"What is the mating connector for 1-770849-1?","answer":"This receptacle housing mates with a SL-156 series male header (pin header) of the same 0.156\" pitch and 11 positions. The header may be straight or right-angle, through-hole or surface-mount, depending on the board layout. The polarizing key on the housing must align with the header's key slot."},{"question":"Is 1-770849-1 polarized?","answer":"Yes, the housing includes a polarizing key that prevents mating with an unkeyed header, ensuring correct orientation in the harness."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1-770849-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1-770849-1 when reusing this data.
