16710-50 Armored Interconnect Cable (Industrial-Grade Sensor Connectivity)

The 16710-50 armored interconnect cable is a 50-foot, 3-conductor shielded solution engineered for demanding vibration monitoring installations. Designed to bridge proximity probes, transducers, and monitoring systems, this cable combines mechanical durability with superior electromagnetic interference rejection—essential for maintaining signal accuracy in high-noise industrial environments.

Built for facilities where downtime costs thousands per hour, the 16710-50 addresses critical challenges: cable damage from mobile equipment, signal degradation in EMI-heavy zones, and premature failure from chemical exposure. Its triple-layer construction—conductor insulation, braided shield, and armored jacket—ensures reliable operation across temperature extremes (-40°C to +85°C) while protecting sensitive proximity measurements from corruption.

Ideal for turbomachinery operators, maintenance engineers, and reliability teams managing 3300 XL, 3300 NSv, and 3500 Series monitoring systems. Whether you're retrofitting aging installations or commissioning new assets, this cable delivers the ruggedness and signal fidelity required for predictive maintenance programs that depend on accurate vibration data.

Core Features & Benefits

✓ Triple-Layer Protection Architecture
Inner PVC/PE composite insulation shields 22AWG conductors, while braided electromagnetic shielding blocks >90dB of interference up to 10MHz. The outer armored jacket resists abrasion, impact, and chemical attack—critical for installations near conveyors, forklifts, and process equipment.

✓ Optimized Electrical Performance
Low-capacitance design maintains signal integrity across the full 50-foot length, preventing the voltage drop and phase shift that compromise proximity probe accuracy. Supports voltage ratings up to 300V AC/DC for compatibility with industrial power environments.

✓ Extended Environmental Range
Operates reliably from -40°F to +185°F, accommodating outdoor installations, steam turbine casings, and refrigeration systems. UV-resistant jacket prevents degradation in sunlight exposure, while moisture barriers block condensation ingress.

✓ Universal System Compatibility
Factory-terminated connectors mate directly with 3300 Series proximitor housings, eliminating field wiring errors. Compatible with all Bently Nevada proximity sensors, Velomitor accelerometers, and tachometer modules using standard 3-conductor configurations.

✓ Simplified Installation & Maintenance
Flexible enough for cable tray routing yet robust for direct burial applications. Minimum bend radius of 10x cable diameter prevents shield damage during installation. Color-coded conductors and shield grounding instructions reduce commissioning time by 40% versus generic cables.

✓ Long-Term Cost Efficiency
Armored construction extends service life 3-5x compared to standard PVC cables in harsh environments. Reduces unplanned maintenance calls, sensor recalibration events, and false alarm incidents caused by cable degradation.

Typical Application Scenarios

→ Steam Turbine Vibration Monitoring
Connect proximity probes on turbine bearing housings to monitoring racks located 50 feet away in control rooms. The armored jacket withstands steam leaks and high-temperature radiant heat, while shielding blocks interference from nearby generator fields. Prevents the signal corruption that triggers false trip alarms during startup transients.

→ Centrifugal Compressor Protection Systems
Link proximitor sensors on compressor casings to 3500 Series rack modules through cable trays exposed to oil mist and vibration. The cable's mechanical strength prevents fatigue failures at termination points, while low capacitance preserves the high-frequency response needed to detect surge and stall conditions.

→ Critical Motor Bearing Surveillance
Route cables from motor bearing caps to permanently installed monitoring systems in facilities where cable replacement requires production shutdowns. The extended temperature range handles motor surface heat, while armored protection resists damage from maintenance activities and mobile equipment traffic.

→ Petrochemical Pump Diagnostics
Install in refineries and chemical plants where cables face exposure to hydrocarbons, caustic cleaning agents, and high-pressure washdowns. The sealed construction prevents chemical penetration that degrades standard cables within months, ensuring continuous pump condition data for predictive maintenance programs.

→ Outdoor Cooling Tower Installations
Deploy in weather-exposed applications where cables endure UV radiation, temperature cycling, and moisture. The UV-resistant jacket and sealed terminations maintain performance through years of outdoor service, eliminating the annual cable replacement cycles common with indoor-rated products.

Technical Parameters & Selection Guide

Selection Criteria:

Choose the 16710-50 when your installation requires distances between 40-60 feet and faces moderate to severe environmental conditions. For shorter runs (under 20 feet) in controlled environments, consider standard extension cables for cost savings. For distances exceeding 60 feet, evaluate signal loss calculations or specify custom lengths to avoid field splicing.

Verify that your monitoring system uses 3-conductor proximity sensors; 2-wire or 4-wire configurations require different cable types. Confirm connector types match your proximitor housings—the 16710-50 uses industry-standard terminations compatible with 3300 Series hardware.

Frequently Asked Questions

Can the 16710-50 armored cable withstand outdoor installation conditions?
Yes, the UV-resistant armored jacket and sealed terminations are engineered for permanent outdoor deployment. The cable maintains full electrical specifications through temperature cycling from -40°F to +185°F and resists moisture ingress in high-humidity environments. Suitable for rooftop installations, outdoor pump stations, and weather-exposed cooling tower applications.

What level of electromagnetic interference rejection does this shielded cable provide?
The braided shield construction delivers greater than 90dB of EMI rejection at frequencies up to 10MHz. This performance level effectively blocks interference from variable frequency drives, welding equipment, radio transmitters, and high-voltage switchgear—common sources of noise in industrial facilities that corrupt unshielded proximity sensor signals.

Is the 16710-50 compatible with vibration monitoring systems from other manufacturers?
While optimized for Bently Nevada 3300 and 3500 Series systems, the standard 3-conductor shielded configuration is compatible with most industrial proximity sensor systems using similar pinouts and voltage levels. Verify connector types and electrical specifications before deployment in non-Bently applications to ensure proper mating and signal integrity.

How does the armored 16710-50 differ from standard proximity sensor extension cables?
The 16710-50 features a reinforced armored jacket that provides mechanical impact protection, abrasion resistance, and enhanced chemical resistance—critical for harsh industrial environments. Standard extension cables prioritize flexibility and cost for indoor, controlled-environment applications. Choose armored cables when routing through high-traffic areas, outdoor locations, or chemically aggressive zones.

Can I splice or extend the 16710-50 cable to achieve longer distances?
Field splicing is strongly discouraged as it introduces impedance discontinuities, potential moisture ingress points, and shield grounding complications that degrade signal quality. For distances exceeding 50 feet, specify factory-terminated custom lengths or use approved extension cables with proper connectors to maintain system integrity and warranty coverage.

What installation practices ensure optimal cable performance and longevity?
Maintain the minimum bend radius of 10x cable diameter during routing to prevent shield damage. Implement single-point shield grounding at the monitoring system end to eliminate ground loops. Secure cables every 3-5 feet in cable trays or with appropriate clamps to prevent vibration-induced fatigue. Avoid routing parallel to high-current power cables; maintain 12-inch separation or use perpendicular crossings to minimize inductive coupling.
