Miniature capsule-type conductive slip ring featuring a brown metal casing with an outer diameter of only 12.4mm. Integrates 12 independent 2A circuit channels within a capsule-sized volume using terminal structure wiring with gold-gold alloy core contact material. Supports maximum operating voltage of 380V and rotation speed of 30rpm, providing stable multi-channel signal and current transmission for space-constrained applications.
Key Features
12.4mm Ultra-Miniature Capsule Design: One of the most compact slip rings on the market, easily integrated into rotating mechanisms with diameter less than 15mm
12-Channel × 2A Multi-Channel Integration: 12 independent channels within capsule volume, each supporting 2A current for simultaneous transmission of multiple sensor signals, control commands, or low-power electricity
Convenient Terminal Wiring: Terminal-type wiring method requires no soldering; electrical connections completed by direct plugging or crimping
Dual Protection with Gold-Gold Contacts: Gold-gold contact materials ensure extremely low contact resistance and excellent oxidation resistance
Durable Brown Metal Housing: Metal housing provides mechanical protection and electromagnetic shielding with enhanced corrosion resistance

Frequently Asked Questions
Q1: Does the 12.4mm outer diameter include the terminal portion?
The 12.4mm is the outer diameter of the slip ring body. The terminal portion is usually located on the end face or side of the slip ring and does not increase the radial dimension. Detailed installation dimension drawings are available from our technical staff.
Q2: What is the specific form of the terminal structure? Which wire gauges are supported?
The terminals are usually crimp or spring-loaded terminals, supporting AWG26-AWG30 wire gauges. You can connect directly using standard terminal plugs or crimp wires using special tools. Customization services are available for special wire gauges.
Q3: Can all 12 2A channels operate at full load simultaneously?
Yes. All 12 channels can provide a total current of 24A at full load. At 380V, the theoretical transmission power can reach 9.1kW. In practical applications, it is necessary to ensure that the power supply capacity matches the heat dissipation conditions. Due to the miniaturization, it is recommended that the continuous total current not exceed 10A for optimal lifespan.
Q4: How protective is the brown metal casing?
The metal casing provides basic dust and moisture protection and electromagnetic shielding. For higher protection levels (such as IP54 dust and splash resistance), we can provide a custom version with enhanced sealing.
