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

Services
By working in this way to help meet our customers’ needs, we have developed more than 30 models and over 900 finished goods. That gives you more detector choices, by far, than you will find from any other supplier. These provide the core products we customize for our customers. There’s no “one size fits all” here. With Dexter detectors, you will not need to compromise on noise, sensitivity, size, and durability. Instead, we have just the right component to help optimize performance for your sensing application.

1SC Compensated
A thin film-based single channel thermopile detector that offers thermal compensation to minimize effects of sudden ambient temperature change during the initial five seconds of change. The 1SC Compensated comes in a TO-5 package with a medium sized 1.0 x 1.0mm active area. Compensation is achieved through the integration of two additional half-sized thermopile elements. Internal aperture is standard and precisely defines active area for applications with FOV and/or spot size requirements.
