LPT012 Series Through Hole Slip Rings

This unit can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure. It is also called a rotary electrical interface, commutator, collector, swivel or an electrical rotary joint. It can improve electromechanical capability, simplify system design, eliminate possible damage while rotating. It’s the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument.

The LPT012 provides an economical, readily available solution when a compact through-bore configuration is required. This unit provides a 12.7mm through-bore for routing hydraulic or pneumatic lines and a compact 55mm outside diameter for minimal space applications. The 5 amps /circuit are available in 6, 12, 18 and 24 ring configurations in 4 housing length. Similar in design to our very popular LPT012 series, this design features long life, fiber brush contact technology for ultimate performance in many challenging applications. Fiber brushes do not require lubrication and produce virtually no wear debris, for maintenance free, life time operation.

LPT Through-bore Slip Rings Installation Guide

1.Arrange wires of the rotor side and the stator side before installation. Stabilize the slip ring on the rotating shaft. Adjust the position of the shaft and the mounting hole and use 4 screws on the rotor side to fasten the components. Ensure the concentricity between the shaft and the

slip ring before fixing the screws,

2.Insert the poke rod in the U slot of the anti-rotation tab. Meanwhile, arrange the wires to avoid twining with the rotor.

3.Slip rings are precise electronic components. Take protection measures in case of harsh environment or apply slip rings with higher protection level.


LPT Through-bore Slip Rings Precautions

1.The slip ring cannot bear the weight of its connected equipment. Also, wires should be free from extra pull and weight.

2.Keep wires intact during installation to avoid any poor performances due to damage of the wire insulating layers.

3.Adopt flexible connection instead of rigid connection between the rotor side and the stator side to ensure longer life span of the slip ring.

4.Stabilize the screws with locking measures to avoid loosening and dropping due to vibrations and shocks during operation
