ARISO contactless connectivity system

03 February 2015

Mouser Electronics is now stocking the new, revolutionary ARISO contactless connectivity system from TE Connectivity (TE). 

This is a system that allows power and data to be transferred between two couplers without any physical contact, resulting in a virtually maintenance free system.
TE’s unique design can offer significant advantages over conventional connector systems by providing rotational freedom, vibration immunity, and unlimited mating cycles while providing connectivity opportunities for systems with rotating parts, connections through walls, on-the-fly connections, high vibration applications, and applications where mating cycles are crucial.

TE’s ARISO contactless connectivity system, available from Mouser Electronics, is a hybrid interconnect system that allows for both power and data to be sent over short distances without any mechanical contact between the two couplers. This permits easy connectivity through materials such as walls, fluids, dust, and harsh atmospheric conditions. Power transfer of up to 12W along with eight PNP channels can be sent between the couplers, which can move at an angle and be subjected to intense vibration without losing signals.

Each coupler contains two transmission mechanisms. On the outside of each coupler is a tightly wrapped circular coil, providing the inductive transfer of power across short distances to a second coupler. On the inside of the circular coil is a loop antenna which allows the transfer of data between the two couplers. Behind each coupler are electronics that manage the transfers and provide an interface to the external devices that are attached to each coupler. The system allows for the transmission of power and data over a distance of 7mm and allows for a misalignment of up to 5mm between the two couplers.

Additional advantages include the significant reduction of issues relating to mating cycles, sealing issues, dust and dirt contamination and vibration. The design supports applications with rotating parts or where connections through walls are required, especially in manufacturing environments such as milling machines, printing drums, robotics, and machines with moving parts, e.g. where sensors need to be connected “on the fly”.
