  • Specification: Cable 4x0.34, box M12, 316L, LED, 9
  • Features: Suitable for M12 plug, integrated LED indication, with 5m PVC cable, 316L lock nut, for hygienic applications.

Selection Recommendations

  • Select the probe protector thread according to the working condition: G1-1/2 or R1-1/2.
  • For hygienic applications, prefer 316L hygienic adapters and cables with connectors.
  • For explosion-proof applications, the Ex protection cover must be installed; otherwise, the explosion-proof certification becomes invalid.
  • The HARTING connector must match the instrument connection thread: M16 or NPTF1/2.

The above spare parts are all suitable for FTI26 and related models. When purchasing, please verify the order number and specifications to ensure compatibility.
