JINPAT Radar System Slip Ring Selection Guide

Selecting a slip ring for a radar system requires balancing considerations regarding size, channel count, environmental conditions, and service life. JINPAT hollow-shaft slip ring series provides precisely matched solutions based on the following key dimensions:

Dimension 1: Spatial Adaptability—Small Aperture, Big Impact

UAV Pods / Airborne Radar: Space is extremely limited; options include ultra-compact outer diameters of 12–20 mm, central through-bores of 5–10 mm, and lightweight aluminum alloy housings.

Shipborne / Ground-Based Radar: Space is relatively ample; options feature central through-bores of 20–50 mm, facilitating the routing of shafts or conduits.

Dimension 2: Signal Transmission—Gigabit Ethernet & Multi-Channel Integration

Power Channels: Supports up to 400V / tens of amperes.

Gigabit Ethernet: One or multiple 1000Base-T channels to facilitate high-definition video streaming and the backhaul of massive data volumes.

Control Signals: Multiple analog/digital channels for encoders, sensors, and other devices.

High-Frequency Channels: Optional coaxial or fiber optic rotary joints are available.

Dimension 3: Environmental Adaptability—IP67 + -30°C to +80°C

Extreme Cold Regions: Features specialized low-temperature grease to ensure smooth, non-stalling startup at -30°C.

High-Temperature Deserts: Utilizes heat-resistant insulating materials to ensure continuous operation at +80°C.

Coastal / Dusty Areas: Features an IP67-rated sealed structure to provide protection against salt spray and dust ingress.

Dimension 4: Reliability & Service Life—Precision Engineering for Long-Term Performance

Contact Materials: Gold-on-gold contact ensures low, stable resistance and superior wear resistance.

Structural Engineering: Incorporates precision bearings and dynamic balancing designs to ensure smooth, stable rotation. Factory Testing: Each slip ring undergoes rigorous testing, including insulation withstand voltage, contact resistance, and continuous rotation aging tests.

Expected Lifespan: Capable of reaching tens of millions of rotations, offering a maintenance-free service life equivalent to that of the radar system itself.

Selection Tips

Please prepare the following parameters: main shaft diameter and available installation space; power supply voltage/current, signal type, and channel count (specifically noting whether Gigabit Ethernet is required); operating ambient temperature and IP protection rating; and requirements regarding rotational speed and service life.
