Selection and Compatibility Guide

If your installation distance differs, we provide various cable length options to ensure minimal signal degradation.

Available Options:

• 16710-20 (20 ft): Current Selection
• 16710-32 (32 ft): View 16710-32 Technical Specs

Technical Suggestion: When selecting between the 16710-20 and 16710-32, verify your probe-to-monitor physical distance. Ensure excess slack is stored in a way that avoids sharp bends, which can compromise the armored sheath and inner shielding integrity.

Professional FAQ

Q: Does the armor require specific grounding procedures?
A: Yes. Ensure the armor is properly terminated to a verified earth ground at the conduit/junction box to maintain the noise-rejection effectiveness of the shield.

Q: Can this cable be used with non-armored proximity probe extensions?
A: While electrically compatible, using armored cable is recommended for all outdoor or high-vibration routing to prevent mechanical failure of the signal path.

Q: What is the primary cause of signal noise in these 22 AWG cables?
A: Signal noise usually arises from improper shield grounding or induced currents from adjacent high-voltage power lines. Ensure cables are routed in separate, shielded conduits.

Q: How does the 3-socket plug ensure connection reliability?
A: The gold-plated 3-socket design minimizes contact resistance. We recommend ensuring the connection is threaded firmly to prevent ingress of moisture or oils common in turbine environments.

Q: Are custom lengths between 20ft and 32ft supported?
A: The 16710 series is manufactured in specific stock lengths. We advise using the closest standard length (e.g., 20ft or 32ft) rather than attempting field splices, which drastically increase the risk of impedance mismatches.

Global PLC Spare HUB's Insight

The 16710-20 is a critical component for vibration diagnostic accuracy. In high-speed turbomachinery applications, even minor signal noise can lead to false-positive alarms or missed vibration trips. Our technical analysis confirms that the factory-molded connectors and heavy-duty armor on the 16710-20 significantly outperform generic field-terminated cabling in preventing erratic sensor behavior. This cable is highly recommended for Bently Nevada 3300 and 3500 monitoring system retrofits.
