Cross-Talk Suppression and Signal Integrity

Maintaining precise electrical continuity between the 11 mm proximity probe and the Proximitor sensor requires strict adherence to system capacitance parameters. The triaxial 75 ohm FEP-insulated architecture shields low-level displacement signals against electromagnetic interference and high-frequency radio transmissions. During system integration, technicians must ensure that total electrical length matches system calibration requirements while verifying that inter-channel routing avoids high-voltage power conduits to eliminate parasitic signal cross-talk.

Delivery Scope Manifest

• 1 x 8.0 Meter 11 mm Extension Cable Assembly
• 2 x ClickLoc Protective Connector Boots

Field Installation and Routing Guidelines

• Bending Radius Limits: Observe manufacturer-specified minimum bending radiuses to prevent internal conductor damage or mechanical stress on the triaxial shield.
• FluidLoc Sealing: Utilize the integrated FluidLoc design to prevent process oil and liquid migration through the cable core into terminal enclosures.
• Connector Engagement: Push and twist the ClickLoc miniature connectors until an audible lock is achieved, securing low-resistance electrical contact under continuous machine vibration.
• Conduit Separation: Route the extension lead through dedicated instrument conduits, keeping absolute physical separation from AC motor power feeds.

Frequently Asked Questions and Technical Responses

• What is the total length designated by the 080 suffix code?

  The 080 suffix indicates an overall cable physical length of 8.0 meters or 26.2 feet.

• What special property does the FluidLoc option provide to the cable?

  It incorporates an internal barrier that blocks oil and process fluids from migrating through the cable core.

• Can this extension cable be used with standard 8 mm proximity probes?

  No, 11 mm extension cables are specifically engineered to match the electrical impedance of 11 mm transducer systems.

• What material is used for the outer protective cable jacket?

  The outer jacket is constructed from fluoroethylenepropylene (FEP), rated for extreme chemical and thermal exposure.

• What is the characteristic electrical impedance of the triaxial conductor?

  The cable is engineered with a strict 75 ohm characteristic impedance profile.

• How are the coaxial connection points secured against loosening?

  The assembly utilizes ClickLoc miniature connectors that mechanically lock to prevent vibration-induced decoupling.

• What is the operating temperature range for the FEP cable jacket?

  The cable assembly functions reliably in thermal environments ranging from -51 deg C to +177 deg C.

• Is grounding required along the intermediate extension cable run?

  The outer shield must be grounded properly at the monitor rack panel to maintain RFI/EMI immunity.
