Professional FAQ

• What makes the armored cable different from standard version?
• The armored version features a protective metal jacket and weighs 103 g/m versus 34 g/m. It provides superior physical protection against crushing, cutting, and abrasion in demanding industrial environments while maintaining the same electrical specifications.
• Can this cable withstand outdoor and submerged conditions?
• While the cable features robust PFA insulation and armored protection, consult the specific installation guidelines for continuous submerged applications. The extended temperature range and armored construction make it suitable for harsh outdoor industrial environments.
• What is the capacitance tolerance for this cable model?
• The typical capacitance is 69.9 pF/m, but for exact tolerance specifications, refer to the detailed engineering specifications. This value ensures proper system frequency response and signal integrity throughout the measurement range.
• How does the armored protection affect installation flexibility?
• The armored construction maintains the same 25.4 mm minimum bend radius as standard cables. The added protection does not compromise installation flexibility but provides enhanced durability in high-traffic or hazardous locations.
• What safety certifications apply to this specific model?
• This model complies with SIL 2/SIL 3 functional safety, EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU, and specific maritime classifications for offshore applications, ensuring reliability in safety-critical systems.
