Request to Exit Sensor - Motion/Presence Sensors
Thermacon - Request to Exit Sensor, Concealed Passive Infrared Motion SensorA concealed and totally silent passive infrared (PIR) motion sensor that detects the presence of natural body heat and activates a relay. Relay activation begins when the detection area is entered and remains on for the duration of the preset relay timing. The unit is designed for concealed and easy installation in suspended ceilings. Four interchangeable detection patterns are standard with each unit. Units accept a power supply range of 12 to 24 volts AC or DC

Security/Detection
If your design challenge is to create the best motion sensor or motion detector - fire sensor or fire detector, smoke sensor or smoke detector - you've come to the right company. Dexter's sensor technologies are at multiple fronts today, reducing the threat of combat on land, sea and air. Yet the industry leading advantages of Dexter sensors - low cost, high sensitivity, low energy consumption and long life - make them the perfect motion sensor for home, office and facility applications. Dexter thin-film and silicon detectors can target precise threats, whether defined by movement, temperature or body mass. Intensive MIL-STD-883H testing performed by Trialon Corporation, an independent testing facility, confirm that Dexter Research's silicon-based temperature sensor detectors meet the same rugged requirements of 1,000G's for mechanical shock and 30G's in random vibration for which our thin-film detectors are famous.

Gas Analysis
Our infrared gas detectors provide superior sensitivity and reliability that may be translated into a more effective early warning system when monitoring atmospheres for gases at trace levels. Our technology also offers the opportunity to perform sophisticated gas analysis. One example: To assure personal safety during a medical procedure, our gas detectors deliver a precise monitoring of the ratio of exhaled gases of a hospital patient who is under general anesthesiology. Another example, no canary need die in a mine if Dexter gas detectors are installed on the job. Infrared lead detectors, whether mobile or mounted, can be a critical element in your health and safety strategy at home and on the job, whatever life forms it is your responsibility to protect.
