LPK series is a group of Pancake Slip Rings manufactured by JINPAT with the thickness as small as 6mm. They are designed exclusively for rotation systems in which installing space is limited in height at vertical direction. Both copper ring and brush contact surround a central hole, which saves space a lot. LPK series slip ring is divided into 2 kinds: separate pancake slip ring LPKS and LPK stand-alone pancake slip ring.
