Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The AEDx-8xxx housed optical encoder is bearing-less and has integrated two-channel quadrature outputs and a third channel index output (A, B, I).
The ungated index output is a positive index pulse that is generated once for each full mechanical revolution of the codewheel.
The quadrature index and power supplied to the encoder are accessed through an eight-pin male connector on a 1.25mm pitch.
This new miniature housed encoder series is designed for use with motors that have shaft diameters from 2mm (miniature version) up to 5mm (standard option).
Moreover, due to the highly collimated light source and the unique photo detector array design, the AEDx-8xxx is extremely tolerant to mounting misalignment.
Avago's AEDx-8xxx series offers several benefits such as minimal installation cost, ease of assembly, high operating frequency that supports miniature servomotors (up to 24,000rev/min), and more accurate position control with the use of an index as a reference point.
This encoder solution is also compatible with SMT automation equipment and pick and place machines.
Moreover, this encoder series can operate in temperatures from -40 to +100C to meet most industrial temperature requirements.
Typical applications include industrial printers and plotters, tape drives, industrial sewing machines, packaging machines and industrial and factory automation equipment.
The AEDx-8xxx series of three-channel incremental encoders will be available from 30th May 2008 through Avago Technologies' direct sales channel and worldwide distribution partners.
