Product Overview

Connector application and structure details

Model: M29-4pin 50A IP68 Waterproof Panel Mount Circular Connector Structure: Front nut locking bulkhead receptacle, matched with in-line cable plug Pin Layout: 4 independent high-current pins, flexible layout for 3-phase power + ground or dual power + dual signal hybrid connection inside equipment enclosures Core Product Advantages 1. Stable 50A High-Current Load Capacity Oversized solid brass contacts with heavy gold plating, contact resistance ≤10mΩ. Continuous full 50A load operation generates low heat and minimal voltage drop, perfectly matching high-power battery inverters and industrial power distribution cabinets, rated up to 600V AC/DC. 2. IP68 Multi-Layer Waterproof & Dustproof Protection Three-tier silicone rubber sealing system includes cable inlet clamping seal, mating surface compression gasket and panel thread integrated O-ring. Fully blocks water immersion, dust, oil mist and moisture, adapting to outdoor cabinets and damp workshop control boxes. 3. Hidden Front Panel Mount Design Bulkhead receptacle adopts rear nut locking installation; all fasteners and wiring terminals are concealed inside the cabinet without exposed external parts, effectively preventing loose connection caused by external pulling or equipment vibration. Standard M29 thread cutout simplifies cabinet drilling and assembly. 4. Rugged Flame-Retardant Shell Housing material: PA66+30% glass fiber reinforced nylon, UL94-V0 flame retardant grade, UV-resistant, shockproof and anti-aging. Stable electrical performance under extreme temperature range of -40℃ ~ +105℃. 5. Easy Maintenance & Safe Mechanical Performance Screw-type terminal wiring requires no professional crimping tools for quick wiring, replacement and on-site maintenance. ≥3000 reliable plug-unplug mating cycles; unique anti-reverse insertion keyway avoids mis-mating and short-circuit risks. Insulation resistance ≥1000MΩ (DC500V), withstand 1500V dielectric voltage for 1 minute to eliminate electric leakage hazards.
