Solar Tracking by Crouzet

Crouzet, the specialist in electromechanical, electronic and embedded computing technologies, has established a presence in the renewable energy sector with its customised offer, meeting the needs of solar panel tracking systems in particular.

For optimum operation and maximum efficiency, solar panels need to be perfectly oriented towards the sun and ideally kept perpendicular to its rays. Crouzet is involved in all phases of solar tracking with products offering automated control of the movement of solar panels, and orienting them precisely.

Smart thinking at the heart of the system

Millenium 3 Smart, the third-generation logic controller developed by Crouzet,acts as the brains of the installation. Simply and intuitively programmed, it manages the position of the solar panels according to precise instructions that enable it to control and automate the actuators (motors and position sensors) making up the installation. It has a specific function block that can be used to set up a dual-axis solar tracking system: the position of the panel is calculated using the location's latitude and longitude coordinates. Installed in a network under the control of a supervisor, logic controllers can bring their intelligence to a solar panel array.

High-performance actuators

The ease of communication between the Millenium 3 and brushless D.C. geared motors such as Crouzet's TNi20, which are used to move the panels, is synonymous with the user-friendly and independent nature of the system: The logic controller and geared motors can operate on 24 V DC, avoiding the need for them to have an additional power supply . These geared motors are very robust and are therefore ideally suited to the harsh and hostile environments of solar tracking applications, which also need the system to operate continuously with numerous stops and starts. Rugged and energy-efficient, they benefit naturally from an extended life due to the lack of internal wear. What's more, the electronics built into the motor feedback data to the logic controller, enabling it to calculate the correct position of the solar panels.

Position sensors offering better safety

Finally, Crouzet offers position sensors that perform the initialization function at the start of travel of panel rotation, as well as a safety function when folding back the panels. These ensure that the Millenium 3 Smart is alerted in the event of any over travel.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
