Encoder Signal Capsule Slip Rings for Robotic Joints
The encoder signal capsule slip ring features a capsule-shaped housing made of PBT engineering plastic with an outer diameter of only 22mm. It integrates four 4A power channels and four encoder signal channels. Using AWG26# Teflon wire, it supports a rotation speed of 200 RPM, providing a compact, reliable, and signal-pure integrated power and feedback connection solution for high-precision rotating mechanisms such as servo motors and robot joints.
Key Features
- Encoder Signal Professional Transmission: Optimized specifically for encoder signal characteristics, ensuring integrity, low noise, and high anti-interference capability of differential signals during rotational transmission, guaranteeing position feedback accuracy.

Frequently Asked Questions
Q1: What types of encoder protocols does this slip ring support?
This product supports the transmission of common incremental (A/B/Z) encoder differential signals, as well as serial digital signals from absolute encoders such as SSI and BiSS-C. For specific protocols, please provide the signal specifications so that we can confirm compatibility.
Q2: What is the protection rating of the PBT capsule housing? Can it be used in harsh environments?
The standard model provides basic dust and moisture protection. PBT material itself has good chemical resistance and insulation properties. If use in harsh industrial environments with oil and splashes is required, we can provide customized enhanced sealing solutions.
Q3: Can the 4-channel 4A channels be used in parallel to obtain a larger single-channel current?
Yes. By connecting them in parallel, the single-channel current output capability can be increased. However, this needs to be specified during the design and selection phase. We will evaluate the thermal load and structure and provide professional guidance on parallel connection. We do not recommend users to modify it themselves.
