Waterproof electric rotary joint for packaging machinery

With 3-5 circuits or ‘ways’ the compact 32mm diameter slip ring assembly is protected against fluid ingress and wash-down processes, without the need for cumbersome and costly protective covers.

Internally the small diameter precious metal alloy rings combine with multiple contact brushes for low peripheral rotating speeds that ensure long lifetime performance and low electrical noise. The precision ball bearing set ensures low friction torque for very smooth operation. The typical maximum voltage is up to 240VAC although 400V versions are also available in larger diameter packages.

The SVTS B series is part of a comprehensive range of slip ring assemblies that are used on continuous or intermittently rotating machinery where electrical power and instrumentation level signals need to be transmitted between stationary and rotating platforms.

In addition to packaging and converting machinery, Heason’s slip rings and rotary joints are used across all areas of machinery and equipment for industry, construction, research, medical and processing etc. Applications include machine tools, rotary tables, carousels, wind turbines, cable winches and more. These devices are available for up to 96 or more ways, combining power and instrumentation circuits which can include TTL, video or fieldbus level signals.

As part of its in-house motion systems design and build service, Heason Technology integrates the slip ring assemblies typically with through-aperture servomotors for positioning and automation systems where feed through of services is required. Servo motors with through-apertures are available as direct drive or standard brushed and brushless types, and complimentary gear units also available.

The SVTS B series is just one example of how Heason Technology provides standard and customised electro-mechanical solutions for challenging motion control and automation applications across a diversity of market areas including aerospace, automotive, defence, robotics, process control, packaging, motorsports and many more.
