Properties of the TOCON_C2 • UVC-only SiC based UV photodetector in TO5 housing with concentrator lens cap • 0 … 5 V voltage output • peak wavelength at 275 nm • max. radiation (saturation limit) at 254 nm is 180 nW/cm2 , minimum radiation (resolution limit) is 18 pW/cm2 • Applications: low UVC radiation detection, occupational safety 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 Vout 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.

- 4. Application Note for TOCONs 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.
