OD 33 slip ring

High Temperature Slip Ring NHG1233

Slip rings of the NHG1233 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.

NHG1233 series with through hole 12mm, OD33mm, suitable for rotating application which requires a through hole ≤12mm, standard model supports 1-12rings signal(0~2A/ring).
