LPT series is a family of robust through bore slip rings, with a central hole up to φ980mm, designed and manufactured by JINPAT with patented technology.
Slip rings of the LPT series have the characteristics of precious metal contact and a long service life up to 230 million turns. Furthermore, they are water-proof, pressure-proof, and vibration resistant. Customizable lead wires and connectors support any plug-in including flying lead.
The through bore can be used to mount the slip ring on a bracket or used for routing hydraulic pneumatic passages as it can integrate pneumatic hydraulic rotary joints, high-frequency rotary joints and fiber optic rotary joints to meet more technical challenges.
