High Temperature Slip Ring NHG1254

Slip rings of the NHG1254 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.

NHG1254 series with through hole 12.7mm, OD54mm, suitable for rotating application which requires a through hole ≤12.7mm, standard model supports 1-24 rings signal(0~5A/ring).
