Product Code : LPK000-0410-8S-E2
Product Description
LPK series is a group of Pancake Slip Rings manufactured by JINPAT with the thickness as thin as 6mm. They are designed exclusively for rotation systems in which installing space is limited in height at vertical direction. Both separate and stand-alone pancake electrical slip rings are available. Reliable contact and ultra-low electrical noise of the light slip ring, together with a high rotating speed are the notable characteristics. They are proven to be of qualified products, secured by the full-fledged quality control center. Moreover, Such Pancake units for encoder are equipped with ready-made photoelectric encoders. Moreover, they can stand the wet calorific test. 360° rotating transmission without surge kind of interference or data package loss wins the customers recognition.
