Johnson Controls TE-635AM-2 Temperature Sensor

The Johnson Controls TE-635AM-2 is a professional-grade 1K Ohm Platinum RTD temperature sensor designed for precise liquid temperature monitoring in Building Automation Systems (BAS) and Direct Digital Control (DDC) applications. Featuring a 6-inch probe length, this immersion temperature sensor is engineered for well mount installation, providing high-accuracy readings within a range of -50?F to 220?F (-46?C to 104?C). The platinum sensing element ensures long-term stability and a resistance of 1,000 ohms at 32?F, making it a reliable component for HVACR contractors managing chiller loops, boilers, or large-scale hydronic systems.

Built with a corrosion-protected steel enclosure, the TE-635AM-2 includes a 0.88-inch hole for standard 1/2-inch conduit fittings, simplifying field wiring for technicians. This model is specifically designed for threadless mounting in TE-6300W Series thermal wells, where the probe is secured via a set screw for optimal thermal contact. The unit meets UL 1995 plenum requirements, ensuring compliance in commercial mechanical spaces while offering a Class A accuracy of +/- 0.35?F at 70?F for demanding environmental controls.

• Platinum Element Stability: Provides superior accuracy and minimal drift over time compared to standard thermistors.
• Rugged Metal Enclosure: Features a steel conduit box that protects electrical connections from physical damage and environmental debris.
• Standardized Compatibility: Works seamlessly with any BAS/DDC system that accepts a 1k ohm platinum RTD input.
• Field-Ready Installation: Shipped with hex-head self-drilling screws for immediate mounting to compatible thermowells.

What is the difference between the TE-635AM-2 and plastic enclosure models?
The "M" designation in this model indicates a metal enclosure, which is preferred for industrial environments or areas requiring International Mechanical Code (IMC) compliance for plenum-rated spaces.

Does this sensor include the thermowell?
No, the TE-635AM-2 is the sensor and enclosure assembly only. To complete the installation, you must order a TE-6300W series thermal well separately.

Can this sensor be used for duct applications?
While optimized for well-insertion, this 6-inch probe uses the same sensing technology as the duct series. However, for duct applications, the TE-6351M-1 is the standard 8-inch alternative.
