Slip ring series PMS – the robust slip ring solutions

The slip ring PMS 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 busts enable the transmission of high electrical power, signals and data from BUS systems.

The bottom part of the housing is made of aluminium, the lid 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 PMS 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 made 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 2 different module sizes available with power ratings of 20A and 50A. Rings and brushes, which are made of 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 PMS also offers the platform for a wide range of special options, such as the use of absolute encoders, microswitches or an additional media feed-through.

B-COMMAND slip ring bodies series KOMBI-PMS
The slip ring KOMBI-PMS is a combination of a normal slip ring for current or data transmission and a solid media distributor for up to 2 passages of gases or liquids. 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 housing is a combination of the simple slip ring PMS, but equipped with the robust media distributor in the lower housing area. The media distributor is made of steel, the cover 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 of the brushes are made by means of radial cable glands. The cabling of the rings takes place through the central tube and is carried out centrally at the bottom of the housing. The inputs of the media distributor are also radial in the lower red area, the outputs are axial at the bottom of the housing.

The separation between rotor and stator takes place centrally on the underside of the base part. Within a radius of 109 mm is the rotating centre section, on which the rings are mounted above the inside of the housing. The brushes are fixed on the bottom part above. There are 2 different module sizes available with power ratings of 20A and 50A. Rings and brushes made of copper graphite as standard can be coated with silver or gold alloy. This leads to an increase in the contact quality and has a positive influence on the wear properties.

The KOMBI-PMS also offers the platform for various special options, such as the use of absolute encoders or microswitches.
