National Instruments / Smart E Tech RTI Strain Relief
The National Instruments / Smart E Tech (SET) RTI Strain Relief (part numbers: 785999-01 (NI), SET-93209 (Smart E Tech)) is a mechanical cable securing and cable protection accessory for use on Rear Transition Interfaces (RTIs) of SLSC (Switch Load and Signal Conditioning) chassis systems. Strain relief is a means of ensuring cable connection integrity is preserved by protecting cables from excessive stress, twisting, or unintentional removal, thereby preserving signal integrity or protecting the connectors. Strain relief is designed for MDK-compatible SET RTIs, providing a solution for making secure, reliable connections in testing applications as in production applications in the industrial automation market.
The strain relief unit is attached to the SLSC chassis along with the RTI using the included M2.5x12 screws, and works in conjunction with cable ties to hold the cables in place securely. This serves the function of redirecting mechanical stresses away from the connectors, thus minimizing wear on the cables as well as on the RTI modules, thereby prolonging their life span. It is essential for applications in environments with high vibration or frequent handling of cables since unshielded connections lead to degradation of signals or damage to equipment.
The strain relief mechanism, suitable for use in various RTI models, meets the specifications of National Instruments, allowing it to be easily integrated with SLSC systems. It is designed according to industrial durability requirements and built to resist environmental extremes commonly found in automated testing and measurement applications, such as temperatures of 0°C to 80°C and relative humidity up to 90%. Using this strain relief allows users to ensure system reliability as well as minimize cable-associated system downtime.
National Instruments/SET RTI Strain Relief is a key accessory in maintaining the integrity of the SLSC platform signal chain, either through PXI or cRIO modules or directly into the unit under measure. Because it is easy to install as well as compatible with standard components, it is an easy upgrade for engineers who need their test systems' mechanical reliability improved.
