Overview

The document details the GT70158 series of through bore slip rings manufactured by Moflon. These slip rings are precision conductive components designed for transmitting power and signals through a rotating interface, featuring a 70mm inner diameter and 158mm outer diameter.

Product Series and Part Numbers

The GT70158 series includes multiple models differentiated by the number of rings, current ratings, and signal capabilities. Part numbers encode key specifications such as ring count, current rating per ring, and signal rings. For example, "GT70158-P0610-S04" indicates a power slip ring with 6 rings rated at 10A each and 4 signal rings rated at 5A.

Electrical Specifications

• Rated Voltage: Power rings up to 690VAC/VDC; Signal rings up to 440VAC/VDC.
• Insulation Resistance: ≥1000MΩ at 500VDC.
• Lead Wires: Power rings use AWG16 Teflon insulated wires; Signal rings use AWG22 Teflon wires.
• Lead Length: Standard 300mm, adjustable upon request.
• Insulation Strength: 500VAC at 50Hz for 60 seconds.
• Electrical Noise: Less than 0.03Ω contact resistance.

Mechanical Specifications

• Working Life and Rotating Speed: Refer to product quality level tables (not included in the document).
• Operating Temperature: -30°C to 80°C.
• Operating Humidity: 0 to 85% RH.
• Contact Material: Precious metals for reliable conductivity.
• Housing Material: Aluminum alloy.
• Protection Grade: IP51 standard.

Customization Options

Customers can request various customizations, which may increase cost by 30% to 50% and extend delivery by 3 to 15 days. Customizable features include:

• Cable exit direction and cable length for rotor and stator.
• Dimensions such as length, height, and outer diameter.
• Support for up to 200 rings for current or signal transmission.
• Optional aviation plugs, terminals, and heat-shrink tubes.
• Hybrid slip rings combining servo control signals, power lines, and encoder lines compatible with brands like Yaskawa, Panasonic, Siemens.
• Support for mixed high-speed data transmission protocols including Ethernet, USB, RS232, RS485, Profibus, CANBUS, CANOPEN, DeviceNET, CC-LINK, ProfiNET, EtherCAT, etc.
• Integration of temperature control signals with thermocouple signals.
• Special environmental adaptations such as quakeproof, high temperature (up to 500°C), high pressure (up to 110KV), military grade, underwater protection (IP65, IP68), and stainless steel housing.
• Hybrid pneumatic/hydraulic and electric slip ring combinations.
• Maximum rotating speed up to 10,000 RPM and maximum current up to 5000 amperes.

Lead Wire Color Coding

The slip rings use a color-coded lead wire system for easy identification. Six wires per group are color-coded as Black, Red, Yellow, Green, Blue, and White. For groups beyond six wires, the colors repeat with numeric codes to differentiate.

Notes and Recommendations

• Multiple 10A rings can be connected in parallel to increase current capacity (e.g., two 10A rings in parallel provide 20A).
• Signal rings rated at 5A can be combined freely with power rings.
• Inner bore sizes smaller than 70mm can be accommodated by adding an inner sleeve.
• Most parts are modular and standard to reduce cost and lead time.
