The TOCON_C1UVC applies a 1 mm² SiC UVC photodiode optimized for wavelengths near ~275 nm, where flame emissions are strong. Its internal amplifier converts tiny UVC signals into a stable 0–5 V voltage output, requiring no external amplification. The hermetic TO-5 packaging with diffuser ensures wide angular coverage, essential for flame detection across different orientations. The design supports both detection of extremely low radiant power (~tens of pW/cm²) and resistance to moderate UVC levels before saturation. This enables fast, reliable detection and response in flame safety control, replacing older discharge-tube sensors with a compact semiconductor solution.

High Sensitivity in UVC Band

TOCON_C1UVC is engineered for maximum sensitivity in the deep UV (UVC) region, where flame emissions are strong and relatively free of ambient interference. The large 1 mm² SiC chip enables detection of very faint flame signals.

Wide Field-of-View Design

Using diffuser optics or a broad acceptance angle, the detector ensures reliable flame detection even when the flame is not perfectly aligned with the sensor—critical in industrial installations.

Integrated Amplifier Output

Its internal low-noise amplifier converts photocurrent directly to a 0–5 V voltage output, simplifying interface to controllers, PLCs, or safety modules without extra signal-conditioning hardware.

Broad Dynamic Range

With a lower detection limit in the picowatt/cm² region and an upper limit of ~180 nW/cm² before saturation (in TOCON_C1 class), the sensor covers both weak ignition events and moderate flame brightness.

Rapid Response for Safety

Optimised for flame detection, the sensor aims for fast rise/fall times enabling swift detection of flame presence or failure, essential for safety interlocks and shutdown systems.

Robust Packaging

The TO-5 hermetic metal housing protects against moisture, dust, EMI, and harsh environments. The UVC-transparent window or diffuser ensures stable spectral fidelity and reliability over time.

UVC-Only Sensitivity (Visible-Blind)

By focusing solely on the UVC spectrum and rejecting visible/IR wavelengths, the sensor minimises false triggers from ambient light, ensuring that only true flame emissions generate output.

Overall, TOCON_C1UVC offers a compact, robust, and sensitive semiconductor alternative to traditional UV flame sensors, merging speed, precision, and ease-of-integration for industrial fire detection systems.

Industrial Burner and Combustion Controls

In gas, oil, or hydrogen-fired burners, TOCON_C1UVC monitors flame presence continuously. On loss of flame, systems can immediately shut down fuel supply, ensuring safe operation.

Fire Alarm & Suppression Systems

It can be used as a sensor input in fire detection systems for industrial zones or enclosures where direct flame UV detection is feasible, improving alarm responsiveness.

Replacement for Discharge Tube UV Sensors

Conventional flame sensors using discharge tubes suffer from wear, high startup voltages, and failure modes. TOCON_C1UVC provides a solid-state alternative that is more reliable and compact.

Hydrogen Flame Detection

Hydrogen flames emit strongly in UVC. This sensor is especially suitable for upcoming hydrogen-based systems where traditional flame sensors may be inadequate.

Safety Interlocks in Process Equipment

Used in kilns, furnaces, boilers, and incinerators to ensure combustion integrity. A lost flame triggers emergency shutdowns, preventing unburned fuel release or explosion risk.

Flame Presence Verification in Gas-Fired Appliances

In HVAC systems, industrial ovens, and burners, the sensor provides flame confirmation feedback to controllers or building management systems.

By combining robust UVC sensitivity, fast response, and visible-blind selectivity, TOCON_C1UVC is ideal for modern flame-detection systems, enhancing safety and reliability across industrial, energy, and process sectors.
