The TE Connectivity 2-1586018-2 is a 22-position, dual-row plug housing from the VAL-U-LOK series, on a 0.165" (4.20mm) pitch. It is a wire-to-wire or wire-to-board interconnect component — the housing itself is the insulator and latching body; the actual electrical path is completed by separately ordered crimp terminals (male pins) that you insert after terminating the wire. Typical applications include power distribution in automotive harnesses, industrial control cabinets, and appliance wiring where the 4.20mm pitch provides adequate creepage for moderate-voltage circuits.
Why the "Contacts Not Included" Note Matters for Your BOM
The first thing to know about this part is that it ships as an empty housing. The 4.20mm pitch and dual-row layout accept standard VAL-U-LOK terminals; confirm the wire gauge range of the terminal against your application before committing the BOM.
Mechanical Retention: Locking Ramp and Panel Mount
This is a field-proven latch design — it does not rely on a secondary locking mechanism, though the VAL-U-LOK system does offer a TPA (terminal position assurance) option on some receptacle housings. The panel mount, snap-in feature allows the housing to be secured into a chassis cutout before the mating half is connected, which simplifies assembly in enclosures where the connector must be fixed in place. The natural nylon body is rated UL94 V-2 by material class, suitable for most indoor equipment environments.
Temperature Range and Environmental Fit
The polyamide (nylon) insulation material handles the lower end without becoming brittle, and the 105°C ceiling is typical for underhood passenger-adjacent locations. If your application sees sustained temperatures above 105°C or requires continuous exposure to moisture or chemicals, consider whether the nylon housing needs a protective boot or a different connector family.
