Signal Path and Interface Details
The cable carries the high-frequency excitation signal from the driver to the probe coil. Subsequently, it returns the modulated voltage back to the Proximitor module. Its 75 Ω impedance matches the probe and driver for minimal signal loss. Therefore, the 330130-080-00-05 preserves measurement accuracy across its full length.
Installation and System Integration
Operators route the cable through conduit or cable trays near rotating machinery. The braided copper shield blocks electromagnetic interference from nearby motors and drives. Meanwhile, the gold-plated contacts resist corrosion in humid plant environments. A minimum bend radius of 25 mm prevents conductor damage during installation.
Energy Storage and Power Considerations
This passive cable stores no energy and contains no battery or capacitor. It simply passes the driver excitation signal to the probe. Consequently, power consumption remains zero for the cable itself. System designers only need to account for the Proximitor driver’s current draw.
