PIR window (without optics)
The PIR window TR231 is ideal for use with the cone TR230 / TR232- and seals it against the environment. It can also be used in simple applications without optics and lenses. The round PIR window TR1201 is specially designed for SMD or small PIR sensors with integrated optics.
For applications for triggering cameras, a restricted lateral viewing angle of approx. 60 degrees together with the cone TR23x is preferred. The PIR window TR1201 with an additional vertical separation device is used for this.
As an alternative solution to the windows, the KUBE PIR transmissive window films can be used for the same purpose.
