Longer sensor runs require a component that can carry accurate temperature information without forcing awkward wiring solutions. This 25 foot sensor is made for installations where distance between the sensing point and the board is part of the design.

The 1/4 inch specification helps narrow compatibility, which is important because temperature related issues are often resolved only when the replacement matches the original sizing and connector style exactly. The two pin connection keeps integration straightforward for the correct control systems.

In field repairs, a failed temperature sensor can create confusing symptoms that mimic heater problems or board faults. Swapping in the right sensor can restore proper communication and return the system to normal logic.

That makes this part valuable not only for maintenance, but for troubleshooting where accurate temperature input is the missing piece.

  • 25 foot length supports longer installation runs
  • 1/4 inch design matches specific applications
  • Two pin connector simplifies compatible hookup
  • Helps restore accurate temperature reporting
  • Useful in both repair and diagnostic work
