What is a TOCON?
A TOCON is a UV photodetector with integrated amplifier converting UV radiation into a voltage. The Vout pin of theTOCON can be directly connected to a controller, a voltmeter or any other data analyzing device with voltage input.
Modern electronic components and a hermetically sealed metal housing with UV glass window eliminate noisecaused by parasitic paths inside the package and EMI. A TOCON is a perfect solution for each industrial UV sensing
application starting from flame or fire detection at pW/cm2 level up to UV curing lamp control at W/cm2 level. This
thirteen orders of magnitude measurement range is covered by ten different TOCONs that differ by their sensitivity.
The TOCONs are produced as UV broadband sensors or with filters for selective measurement.
Silicon Carbide (SiC) detector chip inside
Sophisticated electronics and the sglux in-house produced SiC detector chip featuring a PTB-reported extreme
radiation hardness make a TOCON a reliable component in harsh environments as well as for extremely low or
extremely high UV radiation.

Application Note for TOCONs

4/4

The TOCONs need a supply voltage of Vsupply=2.5 ... 5VDC and can be directly connected to a controller or voltmeter.
Please note that the theoretic maximum signal output is always a little less (approx. 5%) than the supply voltage. To
learn more about perfect use of the TOCONs please refer to the TOCON FAQ list published at www.sglux.com.
CAUTION! Wrong wiring leads to destruction of the device.
For easy setup of the device please ask for a TOCON starter kit.
