The TE Connectivity 2-1586019-4 is a 24-position, dual-row receptacle housing from the VAL-U-LOK series, on 4.20mm pitch with matching 4.20mm row spacing. It is a free-hanging (in-line) housing that accepts female socket crimp terminals — the contacts are ordered separately. The natural PA nylon body carries a latch lock for positive retention when mated with the corresponding VAL-U-LOK pin header.
The Contacts-Not-Included Reality
This housing ships empty — the listing explicitly notes Contacts Not Included. You need to order the matching VAL-U-LOK female crimp terminals separately, in the correct wire gauge for your application. The crimp terminals are typically ordered by a separate base part number (such as the 1586xx series for the socket contacts). Always confirm the terminal part number for your wire size before committing the BOM line.
Mating Half and Termination
This receptacle mates with a VAL-U-LOK pin header of the same 4.20mm pitch and matching position count — a 24-position dual-row header. The latch lock on the housing engages with the header's locking ramp for a vibration-resistant connection. Termination is crimp-style: the socket terminal is crimped onto the wire, then inserted into the housing cavity until the retention lance locks. No soldering or special tooling beyond a standard crimp tool is required.
