SRD040-3P/17S Pancake Slip Ring
Vendor: / Hangzhou Quansheng
Product: SRD040-3P/17S
The SRD040-3P/17S is a 20-circuit pancake slip ring from Hangzhou Quansheng that combines three 15 A power circuits with seventeen 5 A signal circuits for uninterrupted power and control transfer across rotating mechanisms. Power leads use AWG16 tinned copper conductors with PTFE/PVC insulation and are supplied in 500 mm or 1000 mm standard lengths, with custom lengths available. The unit operates from 0 to 250 rpm over -20 to +80 °C and at relative humidity of 60% or higher, while insulation resistance stays at or above 500 MΩ under 500 VDC and the assembly withstands 500 VAC at 50 Hz for 60 seconds. Precious-metal contacts and an aluminum alloy housing support stable low-pressure conduction in a compact IP51 package for robot rotary joints, turntables and industrial automation equipment.
