What is a TOCON?
A TOCON is a 5 Volt powered UV photodetector with integrated amplifier
converting UV radiation into a 0 … 5V voltage output. The V out pin
of the TOCON can be directly connected to a controller, a voltmeter or
any other data analyzing 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 perfect 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 produced SiC detector chip featured by a
PTB-reported extreme radiation hardness.
