SRH50120 Through-Bore Slip Ring
The SRH50120 is a 50 mm through-bore slip ring from Hangzhou Quansheng with a 120 mm outer diameter, a 50 +0.3 mm bore and a 4-M4 mounting flange, allowing cables or shaft structures to pass through while the assembly rotates continuously through 360 degrees. It combines power and signal circuits rated at 380 VAC and 240 VAC/VDC respectively. Power wiring uses AWG16 tinned copper with PTFE/PVC insulation, signal wiring uses AWG22 silver-plated copper with PTFE insulation, and the standard lead length is 500 mm. Dynamic resistance variation is below 0.01 Ω, operating speed spans 0–500 rpm and temperature spans -20 to +80 °C. At 500 VDC, insulation resistance is at least 1000 MΩ for power circuits and 500 MΩ for signal circuits; the assembly also withstands 500 VAC at 50 Hz for 60 seconds. Precious-metal contacts are housed in engineering plastic or aluminum alloy with IP51 protection, axial lengths range from 70 to 220 mm, and configurations can be customized up to 156 circuits. The published starting torque is 0.1 N/m for a six-circuit unit, increasing by 0.03 N/m for every additional six circuits.
