38.1mm Through Bore Slip Ring 12 Way Electrical Rotary Connector 99mm OD

The GK3899-12P series through-hole rotary joint is designed for centralized power supply of rotating equipment. It uses AF200 Teflon wire (default 300mm, customizable) and has a service life of 20 million revolutions. Ideal for wind turbine variable pitch systems, industrial robot joints, and other rotating scenarios requiring multi-channel stable power supply.

• Multi-channel power supply stability: 12 independent power channels support current transmission for 12 devices simultaneously, preventing signal interference in multi-device applications.
• Reliable insulation protection: 800VCA@50Hz power insulation strength + 300VCA signal isolation ensures power safety in industrial environments.
• Wire adaptation flexibility: AF200 Teflon wire can be adjusted for different wire diameters to accommodate various power device connections.
• Long service life: 20 million revolutions design with IP51 protection reduces maintenance frequency for continuously running equipment.
• Environmental adaptability: -30℃~+80℃ temperature range with stable performance in conventional humidity environments (≤85%RH).

• Wind power generation: Connecting rotating nacelle with fixed tower
• Industrial automation/robotics: Rotating worktable, robot joints
• Medical imaging equipment: CT scanner, X-ray machine
• Packaging machinery: Power supply for filling head and labeling head
• Testing equipment: Turntable test, centrifugal test
• Security monitoring: High-speed dome camera
• Ship/maritime: Rotating radar mast, pod thruster
