Thermal Infrared Detectors

Efsen and Excelitas' thermal infrared detectors technology are playing a vital role in creating a healthier, cleaner and safer tomorrow. Excelitas products has gained worldwide recognition for the design and production of high-performance pyroelectric detectors, thermopile detectors and sensor modules which – every day – contribute to safeguarding homes, conserving energy, and providing comfort. From motion and presence detection to gas detection, thermometry and indoor climate control applications.

Pyroelectric detectors

Efsen offers a wide range of Pyroelectric Thermal Infrared Detectors from Excelitas, in both digital and analog models. DigiPyro is the industry’s one and only truly digital pyroelectric thermal infrared detectors family. The DigiPyro Family is setting the standard in digital motion and presence detection.
We offer a complete range of DigiPyro pyroelectric infrared detectors in TO metal housings including our dual-element models, PYD 1788 and 1798; four-element, PYQ 2898 and PYQ 5848; as well as "Smart" DigiPyro models, PYD 1096 and PYQ 1098, with total motion electronics integration.
For high-volume product like motion and presence detection applications, including intrusion alarm systems and energy-saving motion-activated automatic light switches, we offer SMD Pyroelectric Detectors.

Thermopile detectors

Efsen offers Excelitas thermopile sensors for a wide variety of applications including energy-conserving home appliances, intelligent air conditioners, and ear and forehead thermometers.
DigiPile is the revolutionary, digital family of Thermopile Sensors designed specifically for non-contact temperature measurement. The DigiPile Family is offered in traditional TO-46 and TO-5 metal housings as well as our newest SMD model in a ceramic-type package - the TPiS 1S 1253.
At Efsen, you are not limited to off-the-shelf, standard designs. We encourage you to discuss with us and Excelitas, the customization needed to support your infrared sensing applications.
