through hole slip ring 50120

High Temperature Slip Ring NHG50120

Slip rings of the NHG50120 series are specially fit for high temperature 100℃~250℃ working environment such as hot roller, heating device.Grand applies noble precious metal reduced noises and interference between circuits, low friction torque assures long life-span.

NHG50120 series with through hole 50mm, OD120mm, suitable for rotating application which requires a through hole ≤50mm, standard model supports 1-36 power rings(0-20A/ring) or 1-72 signal rings(0~5A/ring).
