Product Description

This pre-crimped finished wiring assembly uses complete authentic Universal MATE-N-LOK matched components:

Female Receptacle Housing: 4-circuit single-row crimp cap housing, 6.35mm fixed center pitch, natural white UL94 V-0 nylon, with integrated panel mounting tabs for fixed equipment wall installation
Dedicated Crimp Terminals: MATE-N-LOK tin-plated phosphor bronze dual-lance contacts, two wire size options: AWG18–24 large current terminal & AWG26–30 signal thin wire terminal
Mating Matching Parts: Male plug housing (4P single row plug housing), vertical/right-angle through-hole PCB header series (wire-to-board conversion), optional TPA terminal position assurance lock to prevent terminal back-out
Matching Cable Spec: AWG18~24 multi-strand power wire, customizable PVC, high-temperature silicone or oil-resistant TPE outer insulation, wire OD φ1.6~3.0mm

Universal MATE-N-LOK is a classic industrial medium-current rectangular connector platform. The 6.35mm ultra-wide pitch provides sufficient creepage and clearance distance between circuits, effectively suppressing high-voltage arc discharge, fully complying with global household appliance and industrial power safety standards. The built-in snap-in positive lock generates obvious tactile feedback after full mating, preventing accidental disconnection caused by equipment vibration, pulling and bumping during long-term operation. Molded polarization key ribs physically block reverse plugging and cross-model mis-mating, eliminating PCB short-circuit burnout risks in mass production assembly wires.

Internal dual-lance terminal retention structure locks crimp contacts firmly inside the housing, with high pull-out resistance to avoid terminal shedding after repeated bending and vibration. The housing reserves panel mounting patch tabs, supporting two installation modes: free-hanging wire-to-wire extension and fixed wire-to-panel wall penetration wiring, adapting diverse equipment structural layout demands. All crimp joints are reinforced with heat-shrink tubing strain relief to avoid wire fracture at bending transition points.

Every finished harness passes strict factory full inspection before shipment: continuity test, terminal pull retention force test, 2000V AC high voltage withstand test, vibration aging test and long-time load temperature rise test. We supply single-end finished cables, male-female inline extension harnesses and cross-type conversion wiring (matched with terminal blocks, aviation plugs) OEM mass customization solutions for home appliance, power tool and industrial automation manufacturers.

Advantages

6.35mm ultra-wide safety pitch high-current design: Larger inter-pin isolation gap than small-pitch connectors, suppress high-voltage arcing, fully meet IEC safety standards for household appliances and industrial power equipment, up to 19A single-pin continuous load capacity.
Dual installation mode compatible housing: Built-in panel mounting tabs support wall fixed wire-to-panel wiring; remove mounting tabs for free-hanging wire-to-wire extension, one housing adapts two mainstream assembly layouts to reduce spare part inventory.
Tactile positive snap locking anti-loose mechanism: Clear click feedback confirms complete mating, fundamentally eliminate incomplete insertion hidden danger that causes contact overheating and melting under long-term heavy load vibration.
Dual-lance double retention terminal structure: Two elastic lances clamp terminals from upper and lower sides, strong anti-vibration performance, avoid terminal back-out caused by wire pulling and equipment reciprocating jolting.
Triple global safety certification (UL/CSA/VDE): Unified standard for EU, US and Canadian market exports, no additional recertification cost for cross-border appliance manufacturers.
Flexible all-round OEM customization support: Arbitrary adjustable cable length, wire thickness and insulation material (ordinary PVC / high-temperature silicone / oil-resistant TPE) according to equipment working environment; small prototype sample orders available for product development verification.
