Single channel pyroelectric detector
Four years ago, in 2014, LASER COMPONENTS expanded its infrared detector range to include pyroelectric devices. LASER COMPONENTS’ Pyro Group manufactures both current and voltage mode devices at their facility in Florida.
A pyroelectric infrared detector responds to a change in IR radiation (heat) absorbed on its surface and they have a very wide spectral bandwidth. A pyroelectric crystal is distinguished by having an atomic structure that will move slightly in response to a change in temperature, rearranging the electric charge within the solid generating a voltage which can be measured using a set of electrodes on the crystal surface.
Pyroelectric detectors are characterised by much higher responsivity than other thermal detectors.
The L210X2020 is a single channel current mode sensor with a split supply of +/-5V. The device is housed in a standard T0-39 four pin package. They have long expected lifetimes making them ideal for fit and forget application such as gas sensing, detecting intruders and identifying the presence of a flame.
