The NI SHC68-68-EPM is a high-performance shielded connectivity cable designed to transmit analog and digital signals between National Instruments (NI) data acquisition (DAQ) devices and terminal blocks or sensors, serving as a critical link in industrial measurement systems. As part of NI’s trusted connectivity portfolio, it ensures signal integrity by minimizing electromagnetic interference (EMI), making it essential for applications demanding precise data capture in noisy factory environments.
In automation setups, the NI SHC68-68-EPM is typically routed through control cabinets, connecting DAQ cards like the NI PCI-6251 to terminal blocks that interface with field sensors. For example, in an automotive test lab, engineers use the NI SHC68-68-EPM to connect a DAQ system to pressure transducers in an engine test cell, where its shielding prevents noise from nearby motors from corrupting critical pressure data sent to the ABB AC 800M controller.
Xiamen Xiongba E-commerce Co., Ltd. Branch specializes in industrial automation distribution and global procurement. We provide a one-year warranty and free replacement service, sourcing DCS, PLC, MVME modules, Anybus converters, RTU modules, industrial PCs, low-frequency displays, and SCSI HMIs to solve procurement challenges with competitive pricing.
The NI SHC68-68-EPM delivers superior signal integrity through dual-layer shielding—foil for EMI protection and braided shielding (90% coverage) for RFI rejection—reducing noise-induced measurement errors by up to 30% compared to unshielded cables. This is critical for low-level signals from sensors like thermocouples or strain gauges.
Integration is seamless, with plug-and-play compatibility with NI DAQ devices and easy pairing with ABB I/O modules in distributed control systems. Unlike generic cables, it features precision-machined connectors with gold plating to ensure consistent contact resistance (<50 mΩ) over thousands of connections. A research lab recently replaced generic cables with the NI SHC68-68-EPM, improving measurement repeatability in vibration tests by 25%.
Rugged construction includes a PVC jacket resistant to oils and chemicals, while integrated strain relief prevents connector damage from cable tugging. Available in 2m, 5m, and 10m lengths, it offers flexibility for cabinet routing without signal degradation.
The NI SHC68-68-EPM excels in environments where signal purity is critical. In manufacturing, it connects DAQ systems to quality control sensors, ensuring accurate measurement of part dimensions in noisy production lines. Research facilities use it in material testing, transmitting strain gauge data without interference from lab equipment.
Power generation plants deploy the NI SHC68-68-EPM to connect temperature sensors in turbine enclosures to DAQ systems, where its shielding withstands electrical noise from generators. A water treatment plant recently implemented the cable to link pH sensors to a monitoring system, resolving signal fluctuations that had caused inconsistent chemical dosing—all while integrating smoothly with existing ABB I/O modules.

Install the NI SHC68-68-EPM by routing it away from high-voltage cables and motor leads to minimize interference—maintain at least 30cm separation where possible. Secure the cable with cable ties, avoiding sharp bends (minimum bend radius: 50mm) that could damage shielding. Connect the VHDCI end to the DAQ device and the D-sub end to the terminal block, ensuring connectors are fully seated and screws tightened evenly.
For maintenance, inspect the cable quarterly for jacket damage or connector corrosion, especially in humid environments. Clean connectors annually with isopropyl alcohol and a lint-free cloth to preserve contact quality. Verify shielding continuity using a multimeter if signal noise increases. Store spare NI SHC68-68-EPM cables in a dry environment to prevent moisture damage to connectors.
