Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The 330877-080-37-00 is an 8.0-meter 3300 XL 50 mm extension cable configuration designed with flexible stainless steel armor and no hazardous area approvals. This industrial cable serves as a critical connection bridge within the 3300 XL 50 mm Proximity Transducer System, linking a 330876 50 mm probe to a 330878 Proximitor sensor. Constructed with a 75-ohm triaxial design and perfluoroalkoxyethylene (PFA) insulation, the cable integrates proprietary FluidLoc technology to prevent oil, water, and other process fluids from migrating through the cable interior.
Compared to unarmored variants, this armored cable offers high-level physical protection in exposed routing pathways where mechanical wear or abrasion is likely. The 8.0-meter length is specifically calibrated to pair with a 1.0-meter proximity probe to achieve a 9.0-meter total system length, allowing accurate differential expansion (DE) or rotor expansion (RX) measurements on oversized shafts and turbines over a broad 27.9 mm (1100 mils) linear range.
This cable is optimized for heavy-industry machinery protection and shaft monitoring systems. Typical installation areas include:
