12-Position, 3-Row Receptacle Housing for Universal MATE-N-LOK
The TE Connectivity 350783-1 is a 12-position receptacle housing from the Universal MATE-N-LOK series, arranged in 3 rows with a 0.250" (6.35mm) row spacing. This is the housing-only shell — contacts are ordered separately and crimped into the cavities. The panel-mount, snap-in design with a locking ramp suits it for harness assemblies that need a vibration-resistant mate in industrial equipment, appliances, and automotive interior applications.
Three rows at 0.250" spacing give this housing a wider cavity layout than a standard 0.165" pitch power connector — the extra space between rows helps when you're routing larger-gauge wire or adding secondary terminal position assurance (TPA) components. The 105°C upper operating limit matches the temperature rating of standard PVC and crosslinked polyethylene wire insulation used in most industrial harnesses. The crimp termination means each wire is individually inserted and retained, allowing field repair or circuit reconfiguration without replacing the whole connector.
