• Extended Temperature Rating: Supports ETR probes up to 218°C (425°F) and cables up to 260°C (500°F) for high-heat applications.

• Superior RFI/EMI Immunity: Operates reliably in fiberglass housings without shielded conduit, meeting CE mark requirements.

• FluidLoc Leak Prevention: Optional cable construction prevents oil and liquid leakage through the cable interior, protecting machinery.

• Corrosion-Resistant Connectors: Gold-plated ClickLoc connectors resist corrosion and maintain secure connections in wet environments.

• High Mechanical Strength: Patented CableLoc design provides 330 N (75 lbf) pull strength, ensuring durability under physical stress.

• Flexible Mounting Isolation: Proximitor sensor base offers electrical isolation, eliminating separate isolator plates in panel or DIN-rail setups.

Ordering Information

Specific Application

• Radial vibration measuring inside thick-walled bearing casings where threads must bypass outer insulation blankets.
• Axial position calibration loops requiring a long structural shank body to traverse external mounting gland configurations.
• Machinery safety setups needing localized industrial certification standards inside regional factory infrastructures.

Installation & Troubleshooting FAQ

Q1: What are the torque limits for securing this long-case forward mounted probe?

A: The maximum rated installation torque for this 3/8-24 UNF case structure is 33.9 N•m (300 in•lbf). For standard field setups, the recommended tightening torque is 11.2 N•m (100 in•lbf). If you are tightening down exclusively into the first three threads of the housing hole, drop your targets to a maximum of 22.6 N•m (200 in•lbf) to prevent structural distortion.

Q2: Why does this configuration feature a long 3.0-inch unthreaded sleeve section?

A: The extended unthreaded option prevents thread binding when routing through thick outer machine brackets or heavy housing walls. It allows field maintenance teams to slide the main probe barrel deep inside a smooth bore before making mechanical contact with the internal thread matrix, facilitating easier physical positioning.

Q3: How do I handle an unstable signal path when routing this unarmored triaxial cable?

A: This unarmored probe relies on its internal FEP insulating jacket for general protection. If you are routing through areas with moving components or sharp structural edges, you must house the cable inside an external rigid or flexible conduit system. Ensure the path respects the minimum cable bend radius of 25.4 mm (1.0 inch) to preserve internal wire insulation.

Q4: Can I splice or solder this 1.5-meter integral cable if it gets accidentally cut during installation?

A: No, proximity probe cables cannot be spliced or repaired using standard field wire methods. The cable is a matched 75Ω triaxial transmission line with precise nominal DC resistance characteristics. Any standard field splice will introduce major impedance mismatches and distort the Proximitor's calibration curve, requiring a complete replacement of the core probe hardware.
