5. Camera I / O
5-1 Power source
The camera is powered through 15-pin connector.
Though ripple-free and stable power source is preferable, the switching supply is also employable. In general,
ripple voltage of a stabilized power source
voltage ripple is added to video signals, S/N ratio degrades when ripple voltage is too large.
When two or more line scanners are connected to a single power source, be sure to keep cables from varying
extremely in length from others. When cable length varies greatly depending installation location of line
scanner and power source, dispersively set up multiple small-capacity power sources.
