Key Engineering Advantages

High Circuit Density

Accommodates multiple video, control, and sensor lines.

RF/FORJ Integration

Supports high-frequency and fiber optic data transmission.

Harsh Environments

Built to withstand moisture, debris, and continuous motion.

Robotic inspection systems—such as sewer crawlers, nuclear pipe scanners, subsea remotely operated vehicles (ROVs), and tank inspection crawlers—are sent into confined, hazardous, or submerged environments to capture real-time visual data. These robots utilize pan-tilt camera heads and rotating scanning sensors that require miniature, highly durable slip rings to operate.

Demands for Crawler & Robot Integration

  • Extreme Compactness
    Slip rings must fit within the slim profile of robotic joints or camera pods.
  • Robust Signal Transmission
    Reliable routing of analog composite video, HD-SDI, or Ethernet signals alongside motor control power.
  • Harsh Environments
    Resistance to water submersion, high humidity, dirt, mud, and chemicals.

Capsule Slip Rings

  • Miniaturized Capsule Diameters
    Form factors from 12.4 mm to 25 mm, weighing only a few grams.
  • RF Coaxial and Fiber Integration
    Capability to run high-frequency coax signals for video or integrate with micro-FORJs for fiber-optic communication.
  • Gold-Alloy Wire Brushes
    High contact density (up to 56 circuits) with very low torque and low wear rates.
  • Environmental Sealing Options
    Customizable IP65-sealed capsules to protect contact surfaces against dust and humidity.
