Contactless connectors delivering major benefits for industrial machinery
R
S Components has introduced a new range of ARISO contactless connectors from TE Connectivity. The ARISO connectivity platform is a hybrid interconnection system that is based on contactless power and data technology and enables easy connectivity over a short distance without physical connection. The connectivity system brings many advantages such as design flexibility, unlimited mating cycles and reduced maintenance costs in industrial and control applications such as robotics, centrifuges, in-line inspection, milling machines, high-end printers, rotating tables and moulding machines. Unlike traditional mechanical cable connectors, ARISO connectors use an inductive magnetic coupling system between transmitter and receiver (M30 x 80mm sized) and thereby do not require physical contact. The connectors are able to transfer data and power not only through air, but also across many
different materials as well as fluids such as oil and water. They will also automatically switch off in the event of a foreign metal object coming between the transmitter and receiver. Designed to replace complex and expensive harness constructions and slip rings to enable connectivity where connections have previously not been possible, the ARISO series comprises five contactless male and female connectors that come with enhanced design specifications. There is also interchangeable dynamic pairing between the ARISO couplers and they are capable of connecting with traditional systems via standard M12 cables. The system’s use of dynamic tuning means that the connectors are able to maintain a connection and avoid misalignment problems caused by shifts in movement. This freedom of movement includes 360° rotation, angular motion or a variable degree of distance between

connectors. This results in a connection that is highly resistant to vibration, as well as making the devices ideal for on-the-fly
connections, such as when connecting remote I/O or sensors on moving machine parts. The connectors are also designed to provide safe and reliable connectivity and offer unlimited mating cycles even in harsh environments via high vibration resistance and fully sealed couplers, which also means significantly reduced maintenance costs. This makes them highly suitable for conditions that are wet, dusty or contain debris and pollutants. The connectors also provide a range of protection features including reverse polarity protection for power and data transmission, protection
against over heating, and IP67 ingress protection.
Overall, with none of the wear and tear due to friction caused by traditional contacts, these contactless connectors have a very high service life. This offers a whole new range of deployment opportunities providing increased design flexibility and cost savings.

T
he GTK range of K series subminiature (2.92 mm) connectors and cable assemblies is ideal for use in high- frequency applications that are typical in military, security and instrumentation markets.
The K series connector is identical to and fully compatible with the SMA connector series by virtue of the same physical dimensions, but it uses an air dielectric, which ensures superior performance at high frequencies. The 50 impedance, screw coupling connectors can operate at up to 40 GHz frequency when used with high performance cables. The outer connector shell is manufactured from stainless steel, with both male and female contacts having a 30µ gold finish as standard. Connectors are available in panel or cable mount types in both male and female versions. K series cable assemblies are manufactured using semi- rigid cables in order to maximise performance at the highest frequency. These assemblies are complemented by end launch and panel-mount jacks as well as in-series adaptors. GTK offers a bespoke production service for RF cable assemblies, utilising almost any combination of cables and connectors, and these are manufactured to the customers’ exact specification. All cable assemblies are 100% tested for continuity, short and open circuits, and contact resistance. All production batches are tested with state of the art network analysers for a minimum of insertion loss and VSWR. Chas Shale, Business Manager for Cable Assemblies at GTK, said, “The K series of RF products offer a higher level of performance than the traditional SMA series, making them more popular for mission-critical and high performance applications.”
