Profile: Dexter Research Center, Inc. specializes in infra red thermophile detectors. Our product line includes temperature products, security detection, laser power & detection products, and security items. Our Thermacon® motion sensors detect the presence of natural body heat and activate a relay. Relay activation begins when the detection area is entered and remains for the duration of the preset relay timing. The unit is designed for concealed and easy installation in suspended ceilings. Our Thermacon® T-80 and S-80 are designed for easy concealed installation in suspended ceilings, or on an enclosed metal electrical box, & is acceptable for use in air handling areas. In addition to the four standard interchangeable detection patterns, others may be custom made. Our ten-channel thin-film thermophile in a TO-8 package offers 10 channels for spectral differentiation for demanding applications.
