Phaetus Thermistor Rapido Plus 2/ Rapido 2F (Updated)

Product Description

Phaetus Thermistor Rapido Plus 2/ Rapido 2F (Updated) is a factory-original, high-precision replacement temperature sensor engineered explicitly for the modern 2nd-generation Phaetus high-flow hotend series. Upgraded to feature a robust, bead-style sensor housing, this PT1000 RTD sensor drops directly into the revised heater block matrix of the updated Rapido Plus 2 and Rapido 2F toolheads. It provides continuous, ultra-accurate thermal monitoring up to 450°C, making it an indispensable tool for processing demanding industrial filaments that require precise temperature regulation.

Unlike standard thermistors, the Phaetus Thermistor Rapido Plus 2/ Rapido 2F (Updated) utilizes a highly sensitive PT1000 resistance element protected by a flexible, white fiberglass insulating sleeve and an integrated steel spring strain relief. This design is specifically tailored to withstand the constant vibrations, extreme multi-axis accelerations, and high-frequency motion dynamics common in high-performance CoreXY systems. Pre-crimped with a standardized 2-pin Molex connector, it installs directly into toolhead breakout boards or main wiring harnesses without requiring custom crimping or soldering.

If your machine has suffered a broken connection from a filament jam or an unexpected thermal runaway error caused by a fatigued wire, this official component restores factory calibration and stability instantly. It ensures that your Klipper firmware reads real-time thermal values with absolute accuracy, eliminating under-extrusion bottlenecks caused by thermal drop and protecting your 3D printer frame from overheating.

Key Features

• High-Accuracy PT1000 Element: Engineered for industrial-grade thermal monitoring, providing highly consistent and reliable tracking up to 450°C.

• Updated Bead-Style Mount: Specially dimensioned to slide seamlessly into the updated retainer plate assemblies of Rapido 2 Plus and 2F heating blocks.

• Fiberglass Structural Shielding: Wrapped in a high-temperature resistant fiberglass sheath reinforced with a flexible metal spring to eliminate wire bending strain.

• Pre-Crimped Molex Termination: Includes a high-grade 200mm electrical harness terminated with a standard 2-pin connector for direct plug-and-play maintenance.

• Klipper Firmware Compatible: Integrates cleanly with open-source control boards, requiring a basic PT1000 configuration adjustment for flawless calibration.

Applications

• Replacing broken, shorted, or unreliable temperature sensors on the updated Phaetus Rapido Plus 2 and Rapido 2F hotend variants.

• Standard workshop maintenance for high-speed toolheads like the Voron Stealthburner to prevent erratic temperature fluctuations.

• Calibrating precise high-temperature printing profiles for advanced materials like Carbon Fiber ABS, Nylon, Polycarbonate, and Peek.
