Professional FAQ & Selection Guide

• Can I use a 7m cable with a 5m Proximitor sensor?
• No. The total length of the probe and extension cable must match the calibrated length of the Proximitor.
• When should I avoid using the included silicone tape?
• Do not use silicone tape if the connection is exposed to turbine oil; use mechanical connector protectors instead.
• What does the 330 N pull strength rating mean for my installation?
• It ensures the cable can withstand the mechanical stress of installation and industrial vibration without separation.
• How do I verify if the cable has internal damage?
• Measure the center conductor resistance; for this 7m model, it should be within the 1.54 ± 0.23 Ω range.
• Is this cable compatible with 3300 XL 8mm Probes?
• Yes, it is specifically designed for the 3300 XL 8mm system for maximum accuracy and interchangeability.
