Description
Pyroelectric materials produce a charge transfer when they
undergo a change in thermal energy. This effect is applied
for detectors that show an output signal similar to alternating
current with a change in the infrared radiation. Such pyroelectric
detectors are used in movement detectors, passive infrared
alarms, and automatic light switches. Detectors based on the
same principle are used for gas monitoring based on the spectral
absorption method.
Dual-Element Types
Dual-element detectors combine two elements which are
connected in reverse polarity to each other to one FET source-
follower output.
Four-Element Types
Four-element detectors combine four elements to two outputs.
The two individual channels allow signal processing to avoid
false alarms and provide redundancy.
Ceiling-Mount Detectors
Ceiling-mount detectors have a special element configuration
suitable for ceiling lens designs. They combine two or four
separate elements into one output.
Single-Element Detectors
This range of detector offers one element with source-follower
output. Different element sizes are available. Most of the
preferred types have built-in thermal compensation. Special IR
windows of narrow bandwidth are offered.
Dual-Channel Detectors
These special designs offer two single-element detectors in one
TO-5 case. Each one is equipped with an individual filter and
provides its own output. Various narrow-band filter windows
can be chosen.
