Electrical Specifications

DC Resistance: 5.3 ± 0.7 ohms (measured between center and outer conductors at 5.0m probe length).
Signal Stability: The 75Ω coaxial cable with FEP insulation maintains 97% signal consistency at 177°C, reducing interference by 15% compared to standard cables.

Mechanical Design & Durability

Material Composition:
Tip: Polyphenylene sulfide (PPS) – heat-resistant up to 260°C (short-term), with a tensile modulus of 3.8 GPa.
Case: AISI 304 stainless steel – corrosion-resistant, with a yield strength of 205 MPa and 1,200-hour salt spray resistance.
Cable: Available in 0.5m, 1m, 5m, or 7m lengths; tested to withstand 600N tensile force without structural damage.

Installation Guidelines:
Probe Case Torque: Max 33.9 N•m (300 in•lb); recommended 11.3 N•m (100 in•lb) for optimal stability.
Connector Torque: Max 0.56 N•m (5 in•lb); finger-tight application ensures 99% connection reliability.
Minimum Bend Radius: 25.4 mm (1.0 in) – tested to 8,000 flex cycles without performance degradation.
Weight: 14-150g (0.5-5.3 oz) – lightweight design for easy integration into compact machinery.
