Overview

Product overview

Key product information and technical features.

NI groups R6868 within its R68F-68F cable product page, which also includes RC68-68 variants with different connector arrangements. Select by the exact part number and connector type rather than treating every variant on that page as interchangeable.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the R6868 shielded?

No. NI specifies unshielded ribbon construction with no twisted pairs.

What length is this R6868?

The supplied catalog record does not identify a length or manufacturer part number. NI lists R6868 variants 182482-0R25 at 0.25 m and 182482-01 at 1 m; neither has been assigned to this item.

Does the R6868 terminate directly in screw terminals?

No. It terminates in two 68-pin connectors. Screw-terminal connections require a compatible external accessory.
