Cables
Certain interface cables can be supplied by MKS, or you may choose to make your own, provided
the appropriate specifications contained herein are maintained. Refer to Figure 3, page 9, for the
part numbers for the cables used with various MKS Readout/Controller Systems.
Note
1. Metal, braided, shielded cables are required to meet CE Mark
certification.
2. To order metal, braided, shielded cables, add an “S” after the cable
type designation. For example to order a standard cable to connect
the 122 transducer to a 152 controller, use part number CB254-2; for
a shielded cable, use part number CB254S-2.
Complete MKS Pressure Measurement System (Pressure Transducer/Power Supply/Readout)
For convenience, when you purchase a complete pressure measurement system with all MKS
components, MKS will supply (at no additional charge) the appropriate shielded cable with
connector(s), in standard nominal lengths.
Interface Cables for Non-MKS Power Supplies/Readouts
Shielded cable assemblies, in a nominal 10' (3M) length, with one end terminated in “flying
leads” (pigtail) fashion are available at nominal cost. Shielded cable assemblies are
recommended, especially if the transducer's environment contains high EMI/RFI noise.
