WS28 4 Pin Aviation Power Connector 500V 25A Metal Threaded Waterproof Plug Socket with GoldPlated Contacts

WS28 4pin power cable connector Key benefits Reliable power connection rated for continuous 25 A current at 500 VAC, suitable for compact power distribution and equipment interconnects. Threaded coupling and zinc alloy shell with chrome plating provide secure mechanical connection and corrosion resistance for repeated use. Goldplated copper contacts and low contact resistance reduce voltage drop and heating for stable performance. IP44 protection when the waterproof cap is installed on the socket, improving resistance to splash and dust in nonimmersion environments. Multiple pin count options and a maximum cable diameter of 15.7 mm allow flexible configuration and easy integration with existing wiring. Main features Contact pin diameter: 2.5 mm, 4 pins Rated current: 25 A Working voltage: 500 VAC Test voltage: 1500 VAC Contact resistance: 1 mohm Insulation resistance: 2000 mohm Wire accommodation: up to 2.5 mm or AWG13 IP rating: IP44 with waterproof cap on socket Coupling type: Threaded coupling Shell material: Zinc alloy with chrome plating Insert material: PPS, maximum temperature 260 C Contact material: Goldplated copper Mating cycles: 500 times Temperature range: 25 to +85 C Pin counts available: 2, 3, 4, 7, 9, 10, 12, 16, 17, 20, 24, 26 Maximum cable diameter: 15.7 mm What you get Plug x1 Socket x1 Waterproof cap x1 Screws x4 set Applications and use scenarios Industrial control panels: Reliable 25 A power feed and robust threaded coupling make this connector suitable for motor controllers, drives, and factory automation modules. Outdoor equipment and lighting: IP44 protection with the waterproof cap and chromeplated shell enable use in outdoor junctions, signage, and stage lighting where splash resistance is required. Audio power and stage setups: Low contact resistance and secure locking are useful for portable power distribution in live event setups and professional audio racks. Why choose this connector Combines current capacity and low electrical resistance for efficient power transfer. Durable materials and threaded coupling deliver secure mechanical retention and long service life through repeated mating cycles. Available in a wide range of pin counts to match multiway power and signal requirements without custom wiring changes. Ordering notes Specify desired pin count from available options when ordering. Ensure correct wire size up to 2.5 mm or AWG13 and cable diameter not exceeding 15.7 mm for proper assembly.
