The shielding helps to protect the signals from electromagnetic interference (EMI) and radio-frequency interference (RFI).

Connector Types:

The cable is terminated with two 68-pin female SCSI 0.050 D-type connectors.

These connectors are commonly used in DAQ systems for connecting modules and accessories.

Design and Durability:

The cable is designed to be robust and durable, ensuring reliable performance in various environments.

It can withstand the rigors of daily use and is suitable for both indoor and outdoor applications.

Applications

DAQ Systems:

The SH68-68-EP cable is ideal for use in DAQ systems that require high-performance, shielded connections.

It can be used to connect DAQ modules to accessories, such as sensors, actuators, and other measurement devices.

Industrial and Test Environments:

The cable is suitable for use in industrial environments, where it can withstand the challenges of machinery, vibration, and other factors.

It is also commonly used in test and measurement environments, such as laboratories and research facilities.

Compatibility

NI Multifunction I/O Devices and Modules:

The SH68-68-EP cable is compatible with a wide range of NI multifunction I/O devices and modules that feature SCSI 0.050 D-type connectors.

This includes many of NI's E-series and other compatible DAQ devices.

Specifications

Conductor Size:

The cable features individually shielded analog input pairs (28 AWG), digital twisted pairs (28 AWG), digital single conductors (28 AWG), and +5 V lines (20 AWG).

Impedance and Capacitance:

The analog input pairs have a differential impedance of 66±8 ohms and a mutual capacitance of 25.5 pF/ft.

The digital twisted pairs have a differential impedance of 100±15 ohms and a mutual capacitance of 17.5 pF/ft.

Length Options:

The cable is available in various lengths, including 0.5 meters, 1 meter, 2 meters, 5 meters, and 10 meters, to accommodate different application requirements.

Additional Notes

RoHS Compliance:

The SH68-68-EP cable complies with the Restriction of Hazardous Substances (RoHS) directive, ensuring that it is environmentally friendly and safe for use.

Alternative Cable:

NI also offers the SHC68-68-EPM cable, which is a newer design featuring additional shielding and specific cable pairings to improve noise performance.

The SHC68-68-EPM cable is recommended for use with certain NI DAQ devices and accessories that require enhanced noise reduction and signal integrity.
