MLG-2

For stringent requirements

Measurement light grids are ideal for complex applications because the beams are evaluated individually and detailed measurement data forwarded to a PLC. Being modular in design, different detection heights and beam separations can be selected. Application: on conveyor belts, automated storage and retrieval systems or for order processing.

Advantages

Strong in performance, versatile in use

Whether transparent, film-wrapped, dark, bulky or with a repeated pattern: the automation light grids from SICK identify objects uniquely and reliably. Our portfolio can handle not only simple switching tasks but also complex volume calculations with maximum precision and reliability. The sensors use state-of-the-art sensor technology for top performance. They are also intuitive to use and are easily integrated into existing systems.
High resolution Even the smallest objects can be reliably detected using light grids. The higher the resolution, the finer the detection. The HLG and the MLG-2 can even detect objects of just 2 mm or 2.5 mm in size. The accuracy also depends on the specific speed and the configured response time.
Short response times The light grids from SICK will impress you with their extremely quick response times. This enables them to detect and accurately pinpoint at lightning fast speeds even small objects moving at high speeds. With response times and minimum dwell times of < 1 ms, the sensors from SICK have been specially designed for high speed manufacturing processes.
Predefined operating modes To ensure a reliable object detection even for the most demanding applications, the light grids come with a number of different pre-defined operating modes. This enables the sensors to be commissioned quickly and easily. Detection and measurement are especially reliable even for transparent objects or at high processing speeds.
Modular design The MLG and SLG product families are modularly designed and can be tailored to meet the particular requirements on-site. Detection height, beam separation and sensing range – you can tailor the automation light grids to your specific application and installation scenario.

ambient conditions

At home in any environment

Whether indoors or outdoors: our automation light grids are rugged, immune to ambient light, and can be operated at temperatures between –30 °C and +55 °C. The numerous designs available cover a wide range of applications. For example, our smart light grids, which are only 8 mm deep and 25 mm wide, can be integrated almost anywhere – whether it be in doors, conveyor belts, machines or shelves. The VLC100 flexibly adjusts the reading field between 40x40 cm and 200x200 cm. And, thanks to its IP 65/67 enclosure rating, the MLG-2 is ideal for the most demanding outdoor applications.

software

Intuitive configuration tool SOPAS

You can intuitively tailor your automation light grids to your requirements using the SOPAS configuration tool. A variety of parameters and functions can be easily configured in this clearly structured application without the need for specialist knowledge on the functioning of the device. The interface visually displays the beams and received energy, and allows telegrams to be quickly created. SOPAS therefore enables specific sensor settings to be implemented in next to no time.

Communication interface

Wide variety of interfaces

Thanks to the integrated interfaces, no additional hardware is required. The measuring automation light grids, for example, communicate with your system via IO-Link. That means better data transmission performance, cloning functions, and the ability to monitor the device state. The MLG-2 ProNet provides additional interfaces such as EtherCAT, ProfiNet, EtherNet IP, CANopen and PROFIBUS. The switching automation light grids are equipped with relays and output signal switching devices.
