FEATURES:

The Hawkeye Electrically Modulated (Pulsable) Series are MEM technology infrared thermal emitters. The Pulsable Series are the perfect solution for applications that require fast electrical modulation, no chopper required. These sources are based on technology, utilizing a thin film resistor. Infrared radiation is the result of heating the film by passing an electric current through it. Due to its low thermal mass, they can be pulsed at frequencies up to 100+ hertz with good modulation depth (contrast between the on and off states). These emitters are powered through the two power leads. Bi-polar drive voltage may be used. The Case Ground Lead is not required under normal operation.

Operating in an enclosed space or a high ambient temperature will generally cause the part to overheat and the drive voltage will need to be reduced to compensate. Please contact us for assistance in determining the proper power factor for the duty cycle to be used in your application and for additional technical data.
