Warsash Scientific presents PerkinElmer’s IR-BLOC family of ambient light sensors, the only silicon photodiodes in the market that come with the IR-blocking feature fully incorporated into a low-cost plastic epoxy package. They offer a spectral response similar to the human eye making them ideal for applications where the response should only be influenced by visible light such as in street light switching, interior and exterior light control, automotive headlight dimmer, contrast control, colorimeters and oil burner flame monitoring.
As part of the IR-BLOC family of ambient light sensors, PerkinElmer is introducing the VTT9812FH, a silicon phototransistor that is offered in a standard, T-1 ¾ end-looking two-lead package. It also offers a cadmium-free alternative to photocells.
- Visible light response with IR-blocking feature incorporated into cast epoxy
- RoHS compliant, cadmium-free alternative to photocells
- Low dark current
- Linear current output over illumination
