Slip ring series PRS in robust aluminium housing

The slip ring PRS is particularly characterised by its robust housing. It can be flexibly adapted to the respective requirements by different cover heights. Various materials for rings and brushes enable the transmission of high electrical power, signals and data from BUS systems.

The bottom part of the housing is made of aluminium, the cover is made of sheet steel. A total of 3 cover heights are available, which can be used depending on the number of rings required.

The cable entries and exits are designed axially. The separation between rotor and stator takes place centrally on the underside of the base part. Within a radius of 75mm is the rotating centre tube, on which the rings are mounted above the inside of the housing. The brushes are fixed on the bottom part above. The simple design of the PRS allows the customer to define the fixed and rotating parts, or whether both parts should rotate relative to each other.

The cable outlet of the brushes is via a cable gland axially on the underside of the bottom part. The cabling of the rings takes place through the central tube with an inside diameter of 42mm.

There are 3 different module sizes available with the respective outputs 20A, 30A and 50A. Rings and brushes, which are made of brass or copper graphite as standard, can be coated with a silver or gold alloy. This leads to an increase in the contact quality and has a positive influence on the wear properties.

The combination of different module sizes or materials of brushes and rings makes the PRS a robust and multifunctional slip ring that provides a cost effective solution for a variety of applications.
