RS-422 slip ring DHK190-50

through-holefor wind turbinefor medical devices

Short Description
Ingiant DHK190-50 is a large-bore through-hole slip ring with a 190 mm inner diameter and 300 mm outer diameter, providing 50 circuits (8×20A/54V, 12×10A/54V and 30×RS422) for combined power and RS422 signal transmission in rotating platforms. Rated IP51 and operating from -40 °C to +65 °C, it is designed for demanding industrial, aerospace and defence applications.

Product Overview
Ingiant DHK190-50 integrates power and RS422 signal channels in a compact through-hole design that allows central shafts, cabling or pipelines to pass through the bore. The unit supports continuous rotation up to 100 rpm and features gold-on-gold contacts and an aluminum-alloy housing for stable electrical performance and reduced wear.
