Reliable power and signal transmission through encapsulated miniature slip rings
Our automation slip rings can be used for more complex tasks in industrial power and signal transmission. Depending on customer requirements, we offer two different qualities of automation slip rings: standard and industrial quality.
The automation slip rings are available in housing diameters of 56 mm, 89 mm and 119 mm in versions with rotor and stator flanges or without flanges. Inside the housing, 2 to 108 rings can be processed for power and signal transmission (Ethernet, USB, RS, CANbus, video signals, sensor signals, etc.). The housing is made of aluminium. Inside the automation slip rings, we use the most advanced fibre brush technology and silver-to-silver or gold-to-gold multi-contacting. The slip rings are characterised by low electrical noise for the transmission of fieldbuses with high data rates, low contact pressure and a long service life. We offer standardised and modularised designs and fully customisable products to meet the specific requirements of customers in various applications. If you have special custom requirements, we will be happy to advise you in order to make the most suitable recommendation for your specification.
Automation Slip Rings
Automation Slip Rings
The task of Automation slip rings is the reliable transmission of signals and power in electrical form. The mechanical movement of the contact surfaces of brushes and rings towards each other with high quality transmission is the decisive challenge. Due to our technical design, electrical noise, which would be generated by sparking, is reduced to an absolute minimum. The electrical noise must be minimised for two reasons: firstly, the noise reduces the quality of the signal transmission and secondly, the noise generates an interference signal which, in the form of electromagnetic radiation, can have a detrimental effect on components in the vicinity of the slip ring body. In complex automation technology, mobile power transmission systems of inferior quality can therefore quickly affect process reliability. For this reason we have developed the series of our Automation slip rings for you. By means of a variety of integrated technologies we reduce potential disturbance variables to a minimum. In this way we protect your production equipment and contribute to efficient operational readiness.
Functionality of Automation slip rings
The structure of the automation slip ring is designed so that each cable leads into the housing on one side and onto a brush, which in turn rests on a separately insulated ring. Another cable leads from the ring on the opposite side out of the housing. The automation slip rings are particularly well suited to their tasks thanks to two features:
- Silver-silver or gold-gold contact surfaces
- Encapsulation by robust aluminium housing
The precious metal surfaces reduce electrical resistance to a minimum. This results in very high-quality signal transmission. Furthermore, the contact pressure of the reinforced and maintenance-free contact brushes is designed in such a way that metal abrasion is minimal. This makes Automation slip rings trouble-free and durable.
The Automation slip rings are completely encapsulated in an aluminium housing. The use of this light metal has numerous advantages. The design can be robust and withstand environmental influences and vibrations. Electromagnetic interference from outside is reliably shielded, which has a positive effect on signal quality. The housings are available with or without a flange. The flanged version has threaded holes for attaching the module. The version without a flange is particularly space-saving.
Advantages of Automation slip rings
The aluminium housing is designed for protection class IP51 in the standard version. This means that it provides complete protection against contact and lasting encapsulation against dust ingress. Depending on requirements, the automation slip rings can be manufactured with different protection classes. Give us a call. Together, we will determine which protection class is best suited for your automation slip rings. The automation slip rings offer you the following advantages:
- Shielding against interference signals
- Impact-resistant housing
- Acid-resistant housing material
- Corrosion-resistant enclosure
- Minimal internal wear
- Highly reliable signal transmission
- Durable ball bearings
The use of a metal housing is ideal for shielding against interference signals and ensuring that signal transmission remains unaffected.
From protection class IP51 onwards, this offers sufficient protection against moisture and dust ingress. This reliably prevents the formation of insulating dust layers on the slip rings. Although the gold or silver contacts are largely resistant to corrosion, contamination of the contact surfaces always has a negative effect on transmission quality, so a suitable protection class is selected depending on the application. Even in their simplest design, Automation slip rings provide reliable protection against these disruptive factors.
The housing is made of thick-walled aluminium. It is highly resistant to vibrations and light impacts. The housing is sufficiently thick-walled to allow for light machining, such as engraving. Aluminium is corrosion-resistant and resistant to most acids and alkalis.
Slip ring technology enables reliable, continuous 360° rotation even at high rotational speeds. This makes automation slip rings suitable for particularly demanding applications in a wide range of areas.
Variants of the Automation slip rings
We offer automation slip rings from two to 125 contacts. Each ring can transmit a rated current of up to 10 amperes. With an operating voltage of 440 Volt AC or 690 Volt DC, these high performance slip rings enable very demanding applications. A residual electrical noise is limited to 10 milliohm. The slip rings allow a maximum rotational speed of 1000 revolutions per minute. They can be used between -30 °C and +80 °C without any problems. Please contact us. We will always find the optimum solution for your slip ring.
Installation of the Automation slip rings
Easy handling is always an important goal for us when developing our products. Despite their high performance and internal complexity, our slip rings can be integrated into assemblies like normal components. The flanged version is recommended for installation in housings or on panels. Chamfered holes are already integrated in the flange. The slip ring bodies without flange require a suitable guide or sleeve on site, which, however, enables deeper integration. The robust aluminium housings can be easily clamped or glued. A linear alignment of the slip ring body is important during assembly. This avoids eccentric movements, which can lead to mechanical stress on the ball bearing. The incoming and outgoing cables are always clearly marked. Mix-ups in the electrical installation are therefore impossible.
Use of Automation slip rings
The Automation slip rings can be integrated at various points in applications. Wherever an electrical contact is required over a 360° rotatable path, Automation slip rings are the ideal choice. This version can also be used for fast rotating applications. The slip rings allow rotations of up to 1000 revolutions per minute.
Maintenance of automation slip rings
The Automation slip rings are maintenance-free. They are not intended to be disassembled, as this would impair their dust and water tightness and their internal structure. Depending on the type, we give you a defined service life for each Automation slip ring. The easy-to-install housing can be replaced without any complications in the event of replacement to ensure the long-term operation of your systems.
