PerkinElmer Debuts New Addition to Digipyro(TM) Family for Motion Detection Applications



New DigiPyro(TM) is World's First Digital Quad-Element Pyrodetector, Providing Improved EMI Immunity and Built-In Temperature Reference Channel

Nuremberg, Germany - SENSOR + TEST 2007 - Booth # 7 / 265 - PerkinElmer Optoelectronics, a global technology leader in digital imaging, specialty lighting and optical detection technologies, today announced the introduction of the newest product in the DigiPyro family of digital pyroelectric infrared sensors, the DigiPyro(TM) Triple Channel, PYQ 2898. DigiPyro products are utilized in a range of home and industrial motion detection applications including intrusion alarm, motion-activated light switches, and door openers.

The DigiPyro Triple Channel, PYQ 2898 is the world's first pyrodetector with a quad- element design with three channels; two pairs of elements representing two channels and an additional temperature reference channel, thereby allowing for more information to be provided to the hosting microprocessor. The triple channel, quad-element detector provides OEMs with performance advantages over traditional analog pyrodetectors, such as reduced system costs and space requirements associated with analog circuitry.

Until PerkinElmer's introduction of the DigiPyro family, traditional detection instrumentation relied upon analog signal processing for motion detection applications. To process an analog signal, these detectors require additional system components such as amplifiers, resistors, capacitors for EMI filtering, and A/D converters - all components that add to system costs without improving performance. PerkinElmer tests have shown that by utilizing the new DigiPyro Triple Channel, PYQ 2898, the power supply rejection ratio (PSRR) is improved by approximately 30 dB or a 32-fold improvement in EMI immunity over analog pyrodetectors.

"Over the past year, our customers have been experiencing great success with the DigiPyro PYD 1998, the first member of the DigiPyro family. We are looking forward to building upon this success with our new Triple Channel pyrodetector model," said Wolfgang Schmidt, Sensors Product Leader, PerkinElmer Optoelectronics.

The DigiPyro Triple Channel offers a 42 bit output "direct link" including a temperature reference, three pin TO-5 housing and improved electrical performance, resulting in reduced system costs.

PerkinElmer Optoelectronics is a global technology leader in digital imaging, specialty lighting and optical detection technologies, providing applications-driven, integrated solutions to leading OEMs in Health Sciences and Industrial Sciences markets.
