Slip ring series PMS - the robust slip ring body

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

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

The cable inputs and outputs are designed axially. The separation between rotor and stator is centrally located on the bottom of the base part.

Within a radius of 75mm is the rotating central tube, on which the rings are mounted above in the interior of the housing. The brushes are fixed above on the bottom part. The simple construction of the PMS leaves the definition of the fixed and the rotating part to the customer, respectively the definition whether both parts should rotate in relation to each other.

The cable exit of the brushes is made via a cable gland axially on the bottom of the base part. The cabling of the rings is done through the central tube with an inner diameter of 42mm.

There are 2 different module sizes with the power ratings 20A and 50A available. Rings and brushes, which are made of copper graphite as standard, can be coated with a silver or gold alloy. This increases the contact quality and has a positive effect on the wear properties.

The PMS also provides the platform for a wide range of special options, such as the use of absolute encoders, microswitches or for an additional media feed-through.
