Dexter’s Specialty Items for Detection
Thermopile Development Tools
Miniature Amplifier PCB –Sized for single channel TO-5 packages and electrically compatible with all Dexter Research Center detectors. Available in three amplifier gains: 300, 500 and 1,000 providing convenient buffering and pre-amplification of thermopile signal. Facilitates fast R&D startup time that can be integrated into your prototypes or final system design.
1010 Low Noise Amplifier – A low noise, DC-coupled amplifier is packaged in a rugged, die-cast aluminum case with BNC connectors enabling input and output. Provides very low voltage noise and current noise in the critical region of 0.1 Hz to 10 Hz making this the ideal amplifier for thermopile detectors in sensitive systems design and laboratory experiments.
Request to Exit Sensor – Motion/Presence Sensors
Thermacon – Request to Exit Sensor, Concealed Passive Infrared Motion Sensor
A 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
There are three different models of Thermacon:
Thermacon Request to Exit Sensor, T-90 UL Listed – The housing is an Underwriters Laboratories Inc. (UL) 94-HB fire rated ABS plastic, coated with aluminum to protect against radio frequency interference.
T-90 Datasheet
Thermacon Request to Exit Sensor, T-80 and S-80 –These units 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.
The T-80 activates both when someone enters the detection area and again at exit and is used for access control and other motion detection where multiple alarms are acceptable or where people may pause for long periods within the detection area before exiting.
The S-80 activates only when the detection area is entered and ignores exits from the detection area. The S-80 is used for annunciation in offices or classrooms where short single alarms are desired.

Usage Notes: All security system technologies from any manufacturer are vulnerable to evasion by a determined expert intruder. Consult with Dexter Research Center before Thermacon installation in critical security applications.
Restroom Motion Sensor – IR Motion Detector – Designed for “smart washrooms”, “smart homes” and other “smart” applications, the Motion Sensor – Motion Detector from Dexter Research Center is targeted for high volume, cost sensitive, drop in applications where the system designer is interested in a fully functional subsystem, with minimum cost and integration effort.

Integrated Temperature Measurement Solutions
Temperature Sensor Module – A low cost solution for non-contact temperature measurements. The sensor is integrated with signal conditioning that reliably produces a calibrated linear digital output in a plug-and-play package having many options. Programmable outputs and flexible power requirements yield a turnkey solution for medical, consumer, commercial and industrial applications.
TSM User Manual (All Models)
Temperature Sensor Module Evaluation Board – The evaluation board is designed to support the Temperatue Sensor Module, quickly allowing customers to configure the Module for different temperature ranges, optics, etc. to find the best configuration to meet their application needs without the need to design any additional hardware.
