Eddy-Current Signal Transmission
The 330130-005-00-00 carries the electrical signal between the 3300 XL 8 mm proximity probe and the associated Proximitor sensor. Its 75 ohm triaxial construction defines the cable impedance and provides the specified capacitance and conductor resistance.
The 0.5 m cable length adds a defined electrical path to the proximity transducer system. Therefore, maintain the specified cable construction and connector interface when replacing the extension cable. Avoid routing the cable alongside high-energy conductors where induced electrical interference could affect the measurement circuit.
Frequently Asked Questions
Q: What type of connector does the 330130-005-00-00 use?
A: It uses miniature coaxial ClickLoc connectors with corrosion-resistant, gold-plated brass construction.
Q: What is the minimum bend radius?
A: The specified minimum bend radius is 25.4 mm (1.0 in). Maintain this radius during installation to avoid excessive mechanical stress.
Q: Does the cable require a separate power supply?
A: No. The cable is a passive signal interconnect and has no specified power consumption.
Field Installation Guidelines
Install the cable between the compatible 3300 XL 8 mm proximity probe and the associated Proximitor sensor. Verify connector compatibility before mating the cable.
Maintain a bend radius of at least 25.4 mm (1.0 in) throughout the cable route. Do not pull the cable by its connector, and keep mechanical loading within the specified 270 N (60 lb) maximum rating.
Keep the cable away from power conductors and other high-interference sources where practical. Protect the cable from abrasion, sharp edges, excessive tensile loading, and repeated bending.
Seat each ClickLoc connector correctly and inspect the mating surfaces before installation. Maintain the specified triaxial cable construction throughout the signal path.
