The Molex 5023800600 is a 6-circuit plug housing from the CLIK-Mate 502380 series, built for wire-to-board interconnects at a 1.25mm pitch.
What's Sold Separately — The Contacts
The listing note reads Contacts Not Included, which is the single most important procurement detail on this page. To build a finished wire harness, you need the matching Molex crimp terminal — typically the 502386 series contact for 1.25mm CLIK-Mate applications. Order the housing and the terminals as separate line items on the BOM; the housing alone does not complete the circuit.
