Hama Quality Cables –<br />
always good performance<br />
Hama cables, adapters and connec<strong>to</strong>rs are always of <strong>the</strong> very best<br />
quality. They form <strong>the</strong> bridge for trouble-free data exchange and<br />
guarantee optimal signal transfer. To scrimp in this area means<br />
minimizing <strong>the</strong> performance of even <strong>the</strong> very best terminal units.<br />
Hama <strong>com</strong>puter cables with integrally extruded plugs and connec<strong>to</strong>rs<br />
offer two advantages: Firstly, <strong>the</strong>se cables will withstand extreme<br />
mechanical strains. Secondly, aluminium foil is incorporated in<strong>to</strong> <strong>the</strong><br />
integrally extruded plugs and sockets for all-round screening against<br />
spurious radiation. A drain wire links <strong>the</strong> foil <strong>to</strong> <strong>the</strong> metal case of <strong>the</strong><br />
plugs or connec<strong>to</strong>rs <strong>to</strong> “drain off” spurious radiation. All contacts are<br />
gold-plated, <strong>the</strong>reby minimizing <strong>the</strong> transmission resistance and<br />
susceptibility <strong>to</strong> corrosion.<br />
Small <strong>com</strong>puter system interfaces (SCSI) have <strong>to</strong> handle very high data<br />
transmission rates when transmitting image data. Loss-free data transfer<br />
is <strong>the</strong> supreme requirement in this context. Compromises are out of <strong>the</strong><br />
question with Hama SCSI cables. Double screening, as well as twisted<br />
pairs of conduc<strong>to</strong>rs, ensure that inductive interference is excluded. This is<br />
where it pays <strong>to</strong> buy quality from Hama!<br />

Each cable lead is soldered one by one on <strong>the</strong><br />
corresponding soldering tag by hand. After that a<br />
100% routine check test with a measuring instrument<br />
is carried out.<br />
To give <strong>the</strong> cable braiding <strong>the</strong> correct electrical<br />
quality <strong>the</strong> so-called non-conduc<strong>to</strong>r is sprayed. To get<br />
a fully operative cable <strong>the</strong> cable leads are also tested<br />
one by one after this work process!<br />
Data signals are sensitive currents. If one byte is lost<br />
during <strong>the</strong> transfer of data, one <strong>com</strong>plete data record<br />
could be lost!<br />
That is why <strong>com</strong>puter cable connec<strong>to</strong>rs/coupler plugs<br />
must be <strong>com</strong>pletely screened. Hama <strong>com</strong>puter cables<br />
are ei<strong>the</strong>r screened with a copper foil (which is<br />
all-round soldered on <strong>the</strong> connec<strong>to</strong>r shell) or an<br />
aluminium foil (without split between <strong>the</strong> aluminium<br />
foil and <strong>the</strong> connec<strong>to</strong>r shell). Of course after this<br />
work process a routine check test of <strong>the</strong> cable is<br />
carried out <strong>to</strong>o!<br />
To finally give <strong>the</strong> cable <strong>the</strong> perfect finish <strong>the</strong> connec<strong>to</strong>r shell is sprayed<br />
and <strong>the</strong> connec<strong>to</strong>r provided with fixing screws, if necessary! Before <strong>the</strong><br />
finished cable is dispatched or s<strong>to</strong>red a routine check test is carried out<br />
again!<br />
Data Transmission<br />
Data transfer rates of <strong>the</strong> different interfaces are often <strong>the</strong> subject of<br />
discussions. To clarify <strong>the</strong> situation <strong>the</strong> following lists <strong>the</strong> most important<br />
interfaces and <strong>the</strong>ir respective transmission rates:<br />
