Frequently Asked Questions

How does armored cable construction improve vibration monitoring reliability?
Armored cables prevent mechanical damage that causes intermittent connections and false alarms. In industrial environments, cables routed through cable trays or along equipment frames experience crushing from adjacent cables, impact from maintenance tools, and abrasion from vibration. The galvanized steel armor absorbs these forces, maintaining conductor integrity and shield continuity for consistent signal quality over 15-20 year service intervals.

What is the maximum total cable length for 3300 proximity sensor systems?
Combined extension cable (probe to proximitor) plus interconnect cable (proximitor to module) should not exceed 200-300 feet depending on transducer model. The 16710-66's 22 AWG conductors minimize voltage drop, but verify your specific proximitor datasheet for exact limits. Exceeding maximum length causes sensor output errors and potential false alarms.

Can I route this cable in the same tray as 480V power cables?
No. Maintain minimum 12-inch separation from 480V lines, 24 inches from higher voltages. While the 95% shield provides excellent EMI rejection, proximity to high-current power cables induces magnetic fields that can exceed the shield's rejection capability. Use separate cable trays or install grounded metal barriers between power and signal cables.

What tools are required for terminal lug installation?
You'll need wire strippers, diagonal cutters for armor trimming, screwdrivers for terminal screws, and a torque screwdriver calibrated to 7-9 in-lbs. Strip armor back 2 inches, remove outer jacket carefully to preserve shield braid, connect shield to ground terminal first, then terminate each conductor with 3/8-inch strip length. Always reference your specific monitoring module's installation manual for exact procedures.

Is this cable suitable for direct burial applications?
Yes, the armored construction and PVC/nylon insulation support direct burial in non-corrosive soils. However, both connector ends require weatherproof enclosures rated IP65 or higher. For burial in corrosive environments or areas with high water tables, consider additional conduit protection or consult with our engineering team for alternative cable specifications.

How do I verify cable integrity after installation?
Use a digital multimeter to measure conductor-to-conductor resistance (should read open circuit), conductor-to-shield resistance (should read open circuit), and shield-to-ground resistance (should read less than 1 ohm). Measure capacitance between conductors (typical range 30-50 pF/foot). Perform megohm insulation resistance test at 500V DC (should exceed 100 megohms). Document baseline measurements for future troubleshooting reference.
