It is a sealed connector housing — the key feature that sets it apart from the standard Mini-Fit Jr. line — designed for wire-to-board power interconnects in environments where moisture or washdown is a concern. ## What the Sealing and Temperature Range Mean for Your Build The sealed feature means this housing, when mated with the matching receptacle and fitted with the correct seal-capable terminals, is intended for applications where the connection point must resist splash, dust, or direct spray. The locking ramp gives a positive tactile latch that resists vibration-induced disconnect; you'll hear it click when the plug seats into the header. ## Mating and Terminal Fit This plug housing mates with the corresponding Mini-Fit Sigma header of the same circuit count and pitch.","metaTitle":"Molex Mini-Fit Sigma 2143720003","metaDescription":"Molex 2143720003 Mini-Fit Sigma sealed plug housing, 10 circuits dual-row, 4.20mm pitch, locking ramp, -40°C to 105°C, ROHS3.
