Johnson Controls TE-635JM-1 Temperature Sensor

The Johnson Controls TE-635JM-1 is a high-precision 1k ohm platinum temperature sensor engineered for demanding duct mount applications in commercial HVAC systems. Featuring an 18-inch stainless steel probe, this unit provides accurate temperature sensing within the air stream, ensuring optimal building automation system (BAS) performance. As the modernized direct replacement for TE-632JM-1, it maintains a consistent resistance-to-temperature curve for seamless field upgrades. The sensor is enclosed in a rugged metal conduit box, making it suitable for plenum-rated installations while offering superior physical protection compared to plastic alternatives. Technical reliability is anchored by the platinum sensing element, which delivers long-term stability and minimal drift under fluctuating thermal loads. Designed for professional contractors, the TE-635JM-1 temperature sensor integrates directly with standard controllers via a 1/2-inch NPT adaptor and includes hex-head self-drilling screws for efficient HVAC sensor installation. This sensor is an essential component for achieving precise environmental control and maximizing energy efficiency in large-scale air handling units.

Key Benefits

• Precise Signal Accuracy: The 1k ohm platinum element provides high-fidelity resistance feedback for critical climate control loops.
• Extended Reach: A 18" probe length allows the sensor to bypass laminar flow and capture accurate core air temperatures in larger ducts.
• Rugged Construction: Built with a stainless steel sensor probe and a metallic conduit box to withstand high-velocity air and meet strict plenum use requirements.
• Simplified Retrofitting: Operates as the official TE-632JM-1 replacement, allowing for fast field swaps without recalibrating existing controllers.
• Installation Ready: Features an integral 1/2-14 NPT threaded well holder and hardware, streamlining the mounting process for the technician.

Common Questions

Is the TE-635JM-1 compatible with my legacy TE-632JM-1 sensor?
Yes, this model is the designated direct replacement for the TE-632JM-1, utilizing the same 1k ohm platinum curves to ensure full backward compatibility with your existing Johnson Controls setup.

Can this sensor be used in plenum spaces?
This sensor features a durable metal enclosure that meets UL 1995 plenum requirements, making it safe for installation in ceiling cavities and air handling spaces.

What wiring distance is supported for this 1k ohm platinum sensor?
To maintain signal integrity and minimize temperature error (typically 1?F error per 150 ft of 18 AWG), total field wiring resistance should be kept under 2 ohms.
