MAMAC Systems TE-205-F-17 Temperature Sensor

The MAMAC Systems TE-205-F-17 is a heavy-duty outdoor air temperature sensor engineered for precise integration into building automation systems and mechanical equipment monitoring. Built with a 20,000 Ohm NTC thermistor, this sensor delivers high-accuracy resistance output essential for critical HVAC control loops. The die-cast aluminum enclosure features a NEMA 4 (IP65) rating, providing a ruggedized housing that protects internal electronics from moisture, dust, and extreme weather. A key technical advantage is the 304 stainless steel probe, which is hermetically sealed to create a monolithic cavity. This design prevents atmospheric contamination and eliminates "thermal drift" caused by high humidity or vibration. Professionals frequently select the TE-205-F-17 for direct thermal contact applications, as its flat-ended probe design ensures a fast response time to rapid temperature fluctuations. With a standard 1/2-inch NPT threaded hub and a liquid-tight cord connector, this 20k thermistor sensor streamlines field installation while maintaining a tight seal against the building envelope.

• Environmental Resilience: The NEMA 4 rated die-cast aluminum housing ensures long-term performance in harsh outdoor climates.
• Precision Sensing: Utilizes a 20,000 Ohm NTC thermistor for accurate resistance readings across typical HVAC operating ranges.
• Hermetic Seal: Stainless steel 304 probe prevents sensor failure caused by thermal shock, moisture ingress, or corrosive contaminants.
• Simplified Installation: Standard 1/2" NPT threaded hub allows for easy mounting to conduit or external brackets without specialized tools.
• Enhanced Accuracy: Liquid-tight cord connectors prevent building air from leaking into the sensor chamber, ensuring true ambient air measurement.

• What is the thermistor curve for the MAMAC TE-205-F-17? It uses a standard 20K Ohm NTC sensor, compatible with most major BAS controllers like Johnson Controls or Honeywell that require 20k-type resistance inputs.
• Can this sensor be used in high-vibration rooftop units? Yes, the monolithic encapsulated cavity is specifically designed to resist failure from mechanical vibration and thermal cycling.
• Does the enclosure protect against water spray? The NEMA 4/IP65 rating is designed to withstand windblown rain and hose-directed water, making it ideal for exposed outdoor locations.
