The 1586845-1: It is designed for panel mount, snap-in installation and uses a latch lock for positive retention — a common choice for wire-to-wire or wire-to-panel power interconnects in appliances, automotive interiors, and industrial control cabinets where the housing must stay put under vibration. Contacts are ordered separately; the housing accepts either male or female crimp terminals, so you can build a plug or receptacle side depending on the mating half.
Mounting and Termination — What You Need for Assembly
This housing snaps into a panel cutout — no tools beyond the panel punch are needed for the mount. The latch lock engages audibly when the mating plug is fully seated, giving a tactile confirmation that the pair is locked. Termination is crimp-style: you select the correct Universal MATE-N-LOK terminal (male or female, depending on your circuit side), crimp it onto the wire, and insert it into the housing cavity until the retention lance clicks. The housing itself carries no contacts — the note is not a warning, it is the standard ordering practice for this series: buy the housing and the terminals as separate line items.
Lifecycle and Sourcing
No official second-source cross-reference is on record. The 4-position housing is sourced per RFQ.
