National Instruments SHC68-C68-D4L

The SHC68-C68-D4L is a shielded, single-ended cable made specifically for high-speed digital devices. It may be used to connect several NI accessories to digital instruments such as the NI 6535/6/7, 654x, 655x, and 657x. It's also compatible with certain Digital I/O Adapter Modules for FlexRIO, Digitizer Adapter Modules for FlexRIO, Signal Generator Adapter Modules for FlexRIO, and high-speed serial instruments.

This flexible cable comes in length options ranging from 0.55m to 2m, making it suitable for a variety of installations. With a characteristic impedance of 50 Ω, the SHC68-C68-D4L guarantees dependable transmission of signals. Because of its shielded design, which reduces interference, it may be used in harsh industrial situations.

The cable performs even better in applications where the least amount of signal loss is required when using the low leakage versions, which come in a length of 1 meter. The cable's maximum voltage tolerance, according to electrical requirements, is ±30 VDC. With values of 0.3 Ω for the 0.55m option, 0.5 Ω for the 1m variant, and 1 Ω for the 2m version, its resistance varies with length. For every length option, propagation delay and channel-to-channel skew are also set.

Capacitance spans from 60 pF to 200 pF. A large variety of devices and accessories are guaranteed to work with the cable thanks to its 68-pin male VHDCI connectors on both ends, which provide 40 single-ended channels. Its 32 AWG wire gauge and 7/40 stranding offer versatility without compromising durability.

The SHC68-C68-D4L satisfies all safety compliance standards, including UL 61010-1, CSA 61010-1, EN 61010-1, and IEC 61010-1, guaranteeing safe use in measurement, control, and laboratory settings. Depending on length and kind, this cable weighs between 175 and 435 grams; it is sturdy and lightweight, making it ideal for a variety of uses. Its shape improves use and convenience by making it simple to fit around unique test setups and other equipment.
