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

The topics of sustainability, flexibility and energy efficiency in the lighting sector are the largest airports in China. Thanks to the wireless and battery-free light switch module from ZF, lights are controlled by using the KNX-RF radio protocol at Beijing and Xinjiang airports.

The first KNX light switch modules from ZF were installed and used in July 2016 at Hetian Airport in the city of Xinjiang. Due to the positive results, Beijing International Airport also expressed interest in the innovative modules. In September 2020 the time came - the energy harvesting light switches from ZF now control the lighting of the VIP rooms at the airport of the Chinese capital.

The reasons for using these innovative ZF light switch modules are varied, but simple. Based on RF and completely free of batteries and cables, the modules can be integrated into a KNX network. After short training, lights can be controlled via the ZF light switch in the same way as traditionally wired light switches. KNX-RF commands transmitted by the switches can be easily transformed into KNX-TP by means of a media coupler. As a wireless solution, however, the ZF light switch offers great flexibility and the option of redesigning the room division in the airport according to individual requirements. This avoids not only maintenance work in the future but also time-consuming measures for battery replacement and disposal. The technical core component of the ZF light switch module is located inside. A small, compact generator (20.1 x 7.3 x 14.3 mm) generates enough energy by mechanical actuation due to the inductive principle. This ensures a reliable radio transmission of commands. With a lifetime of over 1,000,000 switching cycles, it can be operated for many years without any problems.

The wireless light switch module from ZF is uniquely available for the KNX-RF wireless standard without an additional gateway. Due to the KNX protocol structure, the generator requires a high energy yield. With up to 330µWs, the generator from ZF is ideally suited for this application. In addition to KNX-RF, the ZF light switch module also supports the EnOcean3.0 wireless standard and the Bluetooth5.0 Low Energy. It is compatible with commercially available standard frames and can also be combined with customer-specific operating and design panels.

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.
