TY20 2‑Pin Waterproof Connector — reliable, reusable power connection for harsh environments Key benefits Waterproof, threaded design prevents moisture ingress and ensures stable connections in outdoor or damp locations. Solderless screw (no‑weld) crimp connection speeds installation and maintenance; threaded wiring allows repeated use without loss of contact integrity. Low contact resistance and gold‑plated brass contacts deliver efficient power transfer and reduce heat buildup under load. What it does and why you need it Provides a secure, high‑current two‑pole connection for equipment that must withstand vibration, temperature changes and frequent mating. Eliminates time‑consuming soldering while maintaining reliable electrical performance, making it suitable for field installation and service. Key specifications and performance Model: TY20, 2‑pin male/female waterproof connector Wire outer diameter compatibility: 6.0~11.5 mm Wire gauge: 4 mm² / 12 AWG Rated current / voltage: 25 A / 380 V Voltage resistance: AC 1500 V Contact diameter: 2.8 mm × 2 (two contacts) Contact resistance: 1 mOhm Insulation resistance: 2000 mOhm Housing material: PA66 thermoplastic Insulator: PPS thermoplastic, high temperature resistant to 200 C Contact material: brass with gold plating Sealing ring: silica gel Connection type: threaded, solderless screw crimp Temperature range: -25 C to 85 C Durability: more than 500 mating cycles Materials and build quality PA66 housing and PPS insulator provide mechanical strength and thermal stability for demanding applications. Gold‑plated brass contacts offer low resistance and corrosion resistance for long service life. Silica gel sealing ring ensures waterproof performance at the connector interface. Typical applications Outdoor LED lighting and street lighting where waterproof, high‑current connections are required. Industrial machinery and automation equipment exposed to vibration and moisture that need quick, reliable field connections. Marine, RV, or solar system wiring where threaded, repeatable waterproof connections simplify installation and maintenance. Installation notes Use the specified wire gauge (4 mm² / 12 AWG) and ensure outer cable diameter fits within 6.0~11.5 mm for correct sealing. Tighten threaded connection and screw terminals per recommended torque to maintain waterproofing and electrical performance. Designed for repeated mating; verify sealing ring condition after prolonged use and replace if damaged. This TY20 connector combines waterproof sealing, high current capability and solderless installation for dependable, serviceable power connections in demanding environments.
