Overview

The document details the GT38109F Series of through bore slip rings designed for high-speed electrical signal and power transmission. These slip rings feature a 38mm inner diameter and 109mm outer diameter, suitable for applications requiring rotary electrical connections.

Product Specifications

• Dimensions: Inner diameter 38mm, outer diameter 109mm; customizable inner sleeves available for smaller bore sizes.
• Electrical Ratings: Power rings rated up to 10A per ring, with options for parallel connection to increase current capacity (e.g., 2 rings in parallel for 20A).
• Voltage: Power rings support 0~690VAC/VDC; signal rings support 0~440VAC/VDC.
• Insulation Resistance: ≥1000MΩ at 500VDC.
• Lead Wires: AWG16# Teflon for power, AWG22# Teflon for signal; standard lead length 300mm (adjustable).
• Electrical Noise: Less than 0.03Ω contact resistance.

Mechanical Data

• Working Life and Rotating Speed: Refer to product quality level table (not included).
• Operating Temperature: -30℃ to 80℃.
• Operating Humidity: 0 to 85% RH.
• Contact Material: Precious metal contacts.
• Housing Material: Aluminium alloy.
• Protection Grade: IP51 standard; optional IP65 and IP68 for underwater use.

Customization Options

Customizations are available with extended lead times (3-15 days) and increased costs (30%-50%). Options include:

• Cable exit direction and length for rotor and stator.
• Dimensions such as length, height, and outer diameter.
• Support for up to 200 rings for current or signal.
• Aviation plugs, terminals, and heat-shrink tubes.
• Hybrid slip rings supporting servo control signals (Yaskawa, Panasonic, Siemens), power, and encoder lines.
• High-speed data transmission protocols including Ethernet, USB, RS232, RS485, Profibus, CANBUS, CANOPEN, DeviceNET, CC-LINK, ProfiNET, EtherCAT.
• Combination of temperature control and thermocouple signals.
• Special environments: quakeproof, high temperature (up to 500°C), high pressure (up to 110KV), military grade.
• Hybrid pneumatic/hydraulic and electric slip rings.
• Optional stainless steel housing.

Part Number Explanation

Part numbers follow a structured format:

• GT: High-speed slip ring series.
• 38109: 38mm inner diameter, 109mm outer diameter.
• P: Power ring.
• 0610: 6 rings rated 10A each.
• S: Signal ring rated 5A.

Lead Wire Color Coding

Lead wires are color-coded in groups of six: Black, Red, Yellow, Green, Blue, White. For wires 7-12, the same color sequence repeats with a number code pipe to differentiate.

Product Range and Part Numbers

The series includes multiple configurations with varying numbers of power and signal rings and different lead lengths. Examples include:

• GT38109F-P0610-S24 (6 power rings at 10A each, 24 signal rings)
• GT38109F-P1210-S18
• GT38109FF-P2410-S60
• GT38109F-S06 (signal only)
• GT38109F-P3610-S36

Lead lengths vary from approximately 58.6mm to over 400mm depending on the model.

Additional Notes

• Multiple 10A rings can be paralleled to increase current capacity.
• Signal and power rings can be combined flexibly.
• Inner sleeves can be added to reduce bore size below 38mm.
