The 2074580004: It accepts female socket crimp terminals (contacts not included — order separately) and terminates via crimp, making it a free-hanging, in-line connector for wire-to-wire or wire-to-board harnesses. The single-row layout and latch lock fastening give it a straightforward mate/unmate cycle, and the black polyamide (PA66) housing carries a glow wire compliant rating, so it meets the IEC 60695-2-11 test for appliance and lighting applications where a hot component could ignite the connector.
Mating and Termination
This receptacle housing mates with the matching L1NK 396 pin header (male) of the same 0.156" pitch and 4-position count. The female socket contacts are crimped onto the wire and then inserted into the housing — the crimp terminal is not included with this housing, so order the appropriate Molex crimp terminal for your wire gauge separately. The free-hanging (in-line) mounting means no board mount; it sits in the harness and connects to a header on the PCB or to another in-line housing.
