Choose your sensor element

When designing a PIR sensor it is critical to choose the most appropriate pyro sensor. The type and model of sensor (Pyro) needs to be matched to the optical system so that the desired detection area is achieved and so that sensor is able to generate enough signal for detection to be successful.

Typical pyro sensor types

A variety of pyro sensors are available from several manufacturers. Carclo has lenses to support most common sensors.

Please note sensor height
** For some lenses the optical distance is critical- e.g. must equal 3.6+-0.1mm on drawing “Optical Distance” or a spacer under Pyro to achieve correct focal length to lens.lens.

Beware of Pyro Sensor orientation!

REP 05B
Needs to be tested
*     May work with reduced signal.  Recommend trial
**   See above
*** With correct orientation – 90 degree from the drawing on pyro table
