What is a TOCON?
A TOCON is a 5 Volt powered UV photodetector with integrated amplifier converting UV radiation into a 0 … 5V volt-age output. The V out pin of the TOCON can be directly connected to a controller, a voltmeter or any other data analyz-ing device with voltage input. Highly modern electronic components and a hermetically sealed metal housing with UV glass window eliminates noise caused by parasitic resistance paths inside the package or EMI. A TOCON is a per-fect solution for each industrial UV sensing application starting from flame detection at pW/cm2 level up to UV curing lamp control at W/cm2 level. This thirteen orders of magnitude 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 make a TOCON a reliable component in harsh environments as well as for extremely low or extremely high UV radiation. But what makes the TOCON a quasi eternally living sensor is the sglux in-house pro-duced SiC detector chip featured by a PTB-reported extreme radiation hardness.
