Heavy-duty 27 mm-class threaded circular interconnect with M27×1.0/M27×2.0 coupling nut, delivering IP67 as standard (IP68/IP69K optional when mated). Designed for outdoor LED lighting, solar applications, and industrial power systems.
Key Advantages
32A/450V Capacity: Handles streetlight power trunks, 48VDC battery bus, and 230VAC enclosure auxiliary power
Superior Protection: IP67 standard, with optional IP68 (10m) and IP69K ratings for harsh environments
Flexible Installation: Field-wireable screw/solder plug or molded-with-cable options available
Versatile Pin Configurations: 2-28 pins supporting both power and high-density signal applications
Industrial Durability: Copper-alloy contacts, PA66+GF inserts, and robust shell materials
Vibration-Resistant: Threaded M27 lock outperforms quick-lock couplings in demanding applications
Cost-Effective: Lower BOM than M32 connectors while providing adequate headroom for ≤32A applications
