Product Description

Belden’s 1mm (.03937″ pitch) extruded gray ribbon cable was
designed for the disk drive market where the 2mm IDC connector
is widely used. The cable provides improved space reduction, easy
breakouts for circuit routing, and maintains the current carrying
capacity required for these applications. In addition, the electrical
performance meets those requirements specified by the SCSI-3
parallel interface document. The cable is constructed of stranded
28 AWG (7x36) tinned copper conductors. Insulation material
consists of Gray PVC, with a Black polarity stripe for proper circuit
alignment. Standard conductor counts are 26, 34, 40, 44 and 50;
other sizes are available upon request. The cable is UL approved
and CSA certified, and passes the VW-1 Vertical Wire Flame Test.
　

Color Code: Gray with Black polarity stripe.
　

Application: Internal interconnection or internal wiring
of electronic equipment.
