Panel-Mount Plug Housing for 24-Circuit Harnesses
The TE Connectivity 1-640525-0 is a 24-position plug housing from the MR (Miniature Rectangular) series, designed for panel-mount harness applications where a secure, vibration-resistant connection is needed. It uses a 4-row layout with a 0.165" (4.20 mm) pitch and matching row spacing, which means the mating header must have the same 4.20 mm grid — not a standard 0.100" or 2.54 mm pitch.
This is a less common pitch than the 0.100" or 2.54 mm standard, so the mating header must be from the same MR series with a 4.20 mm pitch — not a generic 0.100" header. The 24 positions spread across 4 rows means the connector footprint is more compact in width than a 2-row design with the same circuit count, but the panel cutout must accommodate the 4-row width.
Contacts Are Ordered Separately — What You Need
The housing accepts crimp-terminated contacts that are inserted from the rear and retained by the locking ramp. The housing is available in black or red, which can help with circuit identification in multi-connector assemblies.
