This product is a 3-channel capsule-type slip ring designed specifically for miniaturized precision equipment. It features a high-performance PBT engineering plastic housing with an outer diameter of only 22mm, integrating three independent circuit channels within a compact capsule-shaped body, each capable of stably carrying 5A of current. The product uses AWG22# Teflon wire, supports 220V operating voltage, is designed for a rotational speed of 250rpm, and has an IP40 protection rating. It provides a highly insulated, long-life power and signal rotation transmission solution for small robots, precision instruments, rotary sensors, and compact automation modules.
3-channel 5A capsule slip ring Key Features
22mm Capsule-Style Miniature Design: Its compact size of only 22mm outer diameter makes it one of the smallest slip rings in the industry, easily integrated into devices with millimeter-scale spaces such as robotic arm joints, miniature pan-tilt units, and endoscopes.
PBT Engineering Plastic High-Insulation Housing: Made of PBT material, it possesses excellent electrical insulation, dimensional stability, and chemical corrosion resistance, crucial for ensuring the electrical safety and long-term reliability of miniature devices.
Multi-functional Channels: Provides 3 independent channels, each supporting 5A current, which can be flexibly allocated as power or signal channels, enabling multi-purpose use.
AWG22# Teflon Wire High-Quality Leads: Uses AWG22# silver-plated or tin-plated copper core Teflon-insulated wire, featuring high temperature resistance (200℃), low loss, and anti-aging properties, ensuring long-term stable transmission of signals and current.
250rpm Dynamic Stability: Achieves smooth operation at 250rpm within a compact structure, meeting the speed requirements of most miniature automation equipment. Combined with precision bearings, it has extremely low frictional resistance and smooth rotation.

3-channel 5A capsule slip ring Frequently Asked Questions (FAQ)
Q1: What are the advantages of PBT housings compared to aluminum alloy housings?
A: In miniaturized and precision applications, PBT offers significant advantages:
Excellent electrical insulation: It is an insulator itself, requiring no additional insulation treatment.
Lightweight: Its density is lower than aluminum alloys, reducing rotational inertia.
Corrosion resistance: It is resistant to moisture and chemical corrosion.
Cost-effectiveness: It provides a higher cost-performance ratio while meeting performance requirements.
Q2: Can the 3 channels be used for signal transmission simultaneously?
A: Absolutely. The 5A rated current provides ample margin for most industrial signals (such as 4-20mA, 0-10V, RS485, etc.), providing a clean and stable signal transmission path.
Q3: Why is the rated current of AWG22# Teflon wire 5A?
A: The current carrying capacity of AWG22# wire under standard conditions is approximately 7-9A. We have rated it at 5A to provide sufficient safety margin, ensuring long-term safety and reliability of the wire under dynamic bending at 250rpm and potential temperature rise.
Q4: What environments is IP40 protection suitable for?
A: IP40 means it can prevent the ingress of solid foreign objects larger than 1mm in diameter, but it is not waterproof. It is suitable for clean indoor environments such as laboratories, precision assembly workshops, and medical operating rooms. For use in dusty or humid environments, please consult for a higher protection rating.
