GK3899-12P series through-hole rotary joint is specially designed for centralized power supply of rotating equipment. It uses AF200 Teflon wire (default 300mm, can be customized to meet different wire diameter requirements) and has a service life of 20 million revolutions. It is used in wind turbine variable pitch systems, industrial robot joints and other rotating scenarios that require multi-channel stable power supply.
GK3899-12P series through-hole rotary joint Product Features:
1. Multi-channel power supply stability: 12 independent power channel design supports current transmission for 12 devices at the same time, avoiding signal interference when multiple devices share power, suitable for robot multi-joint collaborative working scenarios.
2. Reliable basic insulation protection: 800VCA@50Hz power insulation strength + 300VCA signal isolation to ensure the power safety of rotating equipment in conventional industrial environments.
3. Wire adaptation flexibility: AF200 Teflon wire can adjust the wire diameter according to the equipment space or current requirements, and is compatible with the connection requirements of different power devices.
4. Long life and low maintenance: 20 million revolutions of service life design, combined with IP51 protection, reduces the frequency of downtime maintenance caused by rotation wear, and is suitable for continuously running industrial equipment.
5. Balanced environmental adaptability: -30℃~+80℃ wide temperature range coverage, taking into account the scene requirements of cold workshops and high-temperature equipment rooms, and stable performance under conventional humidity environments (≤85%RH).
