Excelitas provides photodiodes and IREDs as well as custom assemblies with specified signal level range to address the requirements of electro-optical smoke detectors.An electro-optical smoke detector consists of an infrared LED light emitting diode (IRED) and photodiode assembly which exhibits a signal under the presence of smoke in the detection volume (smoke chamber). Signal range under smoke and clean-air conditions and their long-term stability are key features of a smoke detector module.Such an assembly can be an optical block containing an IRED and PD for (SMD) board soldering or the complete smoke chamber, which are produced in high volumes. In addition to the components presented in the tables above, Excelitas can provide higher value-add assemblies for smoke detection applications, including the following:An optics block which consists in a Photodiode-IRED pair selected, assembled into a plastic housing and tested to have a controlled range of transfer function between the IRED to photodiode signal under given smoke conditions.A smoke chamber with base which can be easily integrated on a PCB for use with the optics block.For further details on these or other sub-assemblies, including readout ICs, please contact the AMS Technologies experts to discuss your requirements.Application: Electro-optical Smoke DetectionPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden.

Users can specify various window sizes to meet desired fields-of-view. PYD DigiPyro dual-element pyrodetectors cover the advanced family of DigiPyros, including Excelitas’ low-power DigiPyros for battery-operated motion detection.Excelitas’ newly improved PYD 1788 and PYD 1798 dual-element DigiPyros are now re-engineered for improved energy efficiency of a mere 1.8 V at 5 µA power requirement, making them ideal motion detection sensors for extended service life in mobile and remote battery-operated devices. Both dual-element pyrodetectors feature two elements in series connection in TO-5 metal housing with optical window options.The PYD 1788 has the standard size window for economy and mid-range sensing, while PYD 1798 has an enlarged window enabling broader fields-of-view. The element configurations are identical, along with the internal electronic circuits. Both the PYD 1788 and PYD 1798 models include a built-in temperature diode which provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal, communicated in one digital bit stream of 2x14-bit output via a single wire “Direct Link” connection to a suitable host microprocessor.The PYD 1794 dual-element Digipyro PIR pyrodetector is the low-profile version of the DigiPyro family and features two elements in series connection in a low-profile TO-39 metal housing with optical window. An internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal.As the latest addition to Excelitas’ DigiPyro detector offering, the PYD 2792 dual-element PIR pyrodetector features two standard elements in parallel connection designed into a compact SMD (surface mount) housing with optical window. This design streamlines integration to the host system with significantly reduced form factor. An internal integrated circuitry converts the element signals into a 14 bit digital data output which can be viewed through the digital interface. And an internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal.The PYD 2592 is the low-power version of PYD 2792, with dual-element pyrodetectors in a compact SMD housing. The sensor includes a fully configurable motion detection unit with an interrupt feature to wake up a sleeping host system. This allows for lowest power consumptions and is therefore ideally suitable for battery operation in compact and mobile applications.An internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal. With its reduced voltage requirements, this device is well suited for battery operation in compact and mobile applications.With a mere 1.8 V power supply voltage and significantly reduced supply current, Excelitas’ PYD 1588 and PYD 1598 are the first real low-power enhanced DigiPyro Pyrosensors. Both are fully integrated, dual-element detectors with two different window size options, offering added features and low-current power consumption for extended remote motion detection in battery operated devices.The power requirements of the system level can be further reduced with the wake-up/sleep feature of this detector series, which also promotes power efficiency and extends service life. PYD 1588 and PYD 1598 low-power DigiPyro pyrodetectors are ideal for prolonged battery-operated motion detection. A selectable band-pass function and pulse count option further compliment the full functionality of these devices.With a diameter of 4.7 mm, the PYD 5731 miniature, dual-element DigiPyro® pyrosensor is one of the smallest designs in the Excelitas pyrodetector portfolio. The PYD 5731 features two miniaturized elements in series connection in TO-46 metal case (4.7 mm dia. X 3.3 mm height) with optical window.The PYD 5731 offers the same Direct Link interface as the regular PYD 1798 DigPyro. The miniature housing, in conjunction with a reduced element size and spacing, enables customers to reduce the size of their optics and innovate more compact product designs.The PYD 2597 Ultra-Low Power DigiPyro sensor extends the DigiPyro Series with one of the lowest power PIR detectors currently available, optimized for battery-operated and remote motion detection systems. It operates at supply voltages as low as 1.4 V and consumes only about 2 µA at 1.8 V, enabling significantly extended service life in energy-constrained designs. The device integrates two fully RoHS-compliant pyroelectric elements with on-chip digitization and a configurable Motion Detection Unit that issues an interrupt on motion detection, allowing the host system to remain in deep sleep until needed. Its single-wire digital interface simplifies host integration while a 130° field-of-view and robust EMI immunity support reliable performance in electrically noisy environments. The PYD 2597 is particularly suited for long-range motion sensing, intrusion alarms, energy-saving controls, horizontal mounting applications and other battery-powered PIR use cases where ultra-low power consumption and compact integration are priorities.Applications: Long-distance Motion Detection (With Lens); Energy Saving Applications; Intrusion Alarms; Horizontal Mounting Applications; Battery OperationPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden.
