MAMAC Systems TE-205-P-4 Temperature Sensor

The MAMAC Systems TE-205-P-4 is a professional-grade space temperature sensor engineered for seamless integration into building automation systems (BAS). This model features a high-stability 1,000 Ohm Nickel RTD (Resistive Temperature Detector) with a 6000 PPM coefficient, providing reliable resistance-based output across an operating range of -40° to 210°F. Housed in a vandal-proof brushed stainless steel plate, the TE-205-P-XX series is specifically designed for high-traffic or accident-prone environments like hospitals, schools, and commercial offices where standard plastic enclosures would fail. The low-profile surface mount design fits a standard 2” x 4” handy box, ensuring NTC/RTD universal compatibility with most HVAC controllers and DDC systems. With an accuracy of ±0.5°F at 70°F, this nickel RTD wall sensor delivers the precision required for tight environmental control without the need for periodic calibration. Its passive sensing technology eliminates the need for external power, reducing potential points of failure in the control loop.

• Vandal-Resistant Design: The stainless steel wall plate provides superior protection against physical damage in public spaces compared to vented plastic housings.
• High-Precision Monitoring: Utilizing a 1,000 Ohm Nickel RTD (6000 PPM) ensures repeatable and stable temperature readings for precision environmental control.
• Streamlined Installation: Designed to mount directly to a standard electrical box with 4.5-inch 22 AWG pigtails for fast wiring termination.
• Wide Compatibility: The positive temperature coefficient (PTC) signal is compatible with a vast array of HVACR automation brands and BAS hardware.

How do I verify if the sensor is functioning correctly?
Using a digital multimeter set to the Ohms (?) scale, measure the resistance across the pigtails. At 70°F (21.1°C), the 1K Ohm Nickel RTD should read approximately 1000 Ohms. Check the 6000 PPM temperature-resistance curve to confirm accuracy at different ambient levels.

Is this sensor suitable for washdown or outdoor environments?
While the stainless steel plate is highly durable, the TE-205-P-4 is an indoor room temperature sensor rated for NEMA 1 applications. For outdoor or high-humidity areas, we recommend using a NEMA 4 rated enclosure to protect the sensing element from moisture and corrosive agents.

Does this unit require a separate power supply?
No. As a passive RTD sensor, it provides a variable resistance output based on temperature and does not require active power, making it a reliable choice for long-term HVACR deployments.
