Finder’s 7T Series multi-function thermo-hygrostat and thermostats are a must-have for panel and machine builders needing a space-saving solution to help detect and maintain optimal temperature and humidity within their control panels, particularly in changing environments.

Imperative for applications where the need to control temperature and humidity is vital, such as in drying kilns, road/tunnel lighting, industrial furnaces, refrigeration, and transportation, Finder’s 7T Series detects and maintains the correct humidity depending on ambient temperatures, all within a multi-functional, 35mm rail mounting (EN 60715), compact 17.5mm size.

With thermostat full-scale accuracy at -1…+3K, and hygrostat accuracy within 5%, and a nominal voltage of 110 … 240 V AC/DC, the combined unit of the Type 7T.51 is both space-saving and cost effective. It’s 1 NO 10 A contact allows for direct control of heaters and fans, without a separate modular contactor.

Maintaining constant temperatures in control panels and enclosures, the 7T Series thermostat suits the needs of both simple and sophisticated heating and ventilation systems. It features a snap action thermostatic bimetallic contact sensor and direct switching of heater loads up to 2500 V A and fan loads up to 130W.

Finder’s Type 7T.51 panel thermo hygrostat has a temperature range of +10…+60°C, and the Type 7T.81 thermostat has a temperature range options of -20…+40°C and +0…+40°C. All products protecting components within control panels ensuring long electrical life. The Type 7T.81.0.000.240x thermostat is for heating control, so should the panel temperature fall below the (minimum) set temperature the contact will close to call for heat. The contact will open when this set temperature is exceeded. tHE Type 7T.81.0.000.230x is for ventilation, so should the panel temperature exceed the (maximum) set temperature then the contact will close to call for cooling. The contact will open when the temperature falls below this set temperature.

Created for professionals, Finder’s LED panel lights are the optimal solution for illuminating machinery and electrical panels of all types.

The 7L Series offers operational efficiency and is especially useful for providing increased visibility where an in-built, moveable light source is required for testing, maintenance and operational work. It is also ideal for automotive electricians who require illumination of the engine bay or vehicle control systems.

Their high practicality allows for the interconnectable lights to be easily positioned anywhere within the electrical panel, thanks to the direct magnetic mounting or through screw supports.

Styled in collaboration with the Minelli | Fossati design studio, the 7L Series LED panel lights have style and elegance matched with great functionality. The light can be controlled by an ON/OFF button, via an integral PIR movement detector, or with direct switching and can be individually wired through push-in quick-connect terminals, or via plug-in connectors for the multiple connections of up to seven lamps.

The 7L Series LED panel lights emit a 5000 K cool white light with low power consumption and a radiated angle of 120°, providing a low thermal footprint. There are also 12...48V and 110...230V AC/DC supply versions available according to levels of brightness:

- LED panel light Type 7L.43 – 600 lumens
- LED panel light Type 7L.46 – 1200 lumens

Finder’s 7H Series panel heaters are ideal components to prevent condensation and ensure the optimum temperature within electrical panels.

Imperative to increase temperatures within control panels to keep components operating efficiently, Finder’s range of fan assisted panel heaters have heating power options from 25 - 50 - 100 - 150 - 250 and 400 W and a power supply of 230 V AC or 110…230 V AC/DC.

The 7H Series has fast wiring terminals, is vertically positioned within enclosures and is 35mm rail (EN 60715) mountable with a clip, saving installation time. The 7H Series panel heaters also have the smallest footprint in the market, taking up minimal space inside enclosures.

The 7H Series has an aluminium profile encased in a plastic housing making it safe to touch, preventing any injuries with contact. The operating temperature of the panel heaters is -40...+50°C, keeping vital components at the perfect temperature to run smoothly. The heaters also have a PTC self-regulating heating system. PTC heaters draw maximum power when cold to provide rapid heating to the optimum temperature. Being self-regulating, as the temperature increases, the power consumption simultaneously drops. Installing the 7H Series with a 7T Series thermostat creates a dynamic heating system that is not only effective in preventing condensation, but also time and energy efficient.

Finder’s panel heaters are suitable for drying kilns, hoists & cranes, plastic moulding machines, automatic car washes, forced air ventilators and many more applications. The 7H Series in conjunction with Finder’s 7T Series panel thermo hygrostats and thermostats, 7F Series filter fans and 7L Series LED panel lights ensures a high-quality thermoregulation system working at peak performance for all applications.

Finder was one of the first manufacturers to integrate NFC technology for the programming and control of its devices (first launched in 2015). NFC programming, which until now has only been available on Android smartphones, is now also possible on Apple devices (iPhone 7 and later).

With the Finder Toolbox NFC app for iOS you can now program from your iPhone various products such as the Finder SMARTimer, and numerous Finder time switches and digital astro switches. In 2019 Apple estimated that there were more than 900 million iPhones in use worldwide, hence this app will allow a large number of new users to take full advantage of the Finder range of NFC smart products, boosting sales of the 12 and 84 Series.

New features of the Finder Toolbox NFC app for iOS include:
• Simplified user interface and experience
• New faster and more intuitive menus
• Quicker upload time and overall performance

What are the advantages of NFC?
• Easier reading of devices inside electrical panels
• Faster programming via the app and easier maintenance
• The possibility of naming and saving configurations
