High Temperature Slip Ring NHG120250

Slip rings of the NHG120250 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.

NHG120250 series with through hole120mm, OD250mm, suitable for rotating application which requires a through hole ≤120mm, standard model supports 1-48 power rings(0-20A/ring) or 1-96 signal rings(0~5A/ring).
