Abacus releases Murata Magicstrap RFID tags

Abacus has released Murata Magicstrap RFID tags that can be glued onto a PCB, requiring no electrical connection.

The tags are readable through an instrument case and support global frequencies, giving a simple, fast and convenient method of tracking electronic systems down the supply chain and through their lifecycle.

Murata Magicstrap RFID tags from Abacus can use the PCB ground as an antenna, but connect to the antenna pattern via inductive coupling.

This eliminates the need for an electrical connection between the tag and the board, and allows the tags to be placed with millimetre accuracy.

According to Abacus, legislation on the recycling of electronic systems has created a need to identify individual electronic systems accurately from manufacture through distribution to end customer and disposal.

RFID tags can be updated with new information as a product progresses through the manufacturing and shipment process - and provide the ideal solution for this requirement.

Murata's has developed a tag with all of the RF circuitry embedded, that can be attached to target boards with no need for RF design.

Reference designs for the antenna pattern required are available free from Murata.

The Magicstrap antenna circuit is wideband, allowing tags to be read and updated over distances of up to 5m at frequencies of 800-1,000MHz.
