  • Guide photovoltaic modules

    The cost-effective and reliable solution for position determination

    The solution

    Our BES inductive sensors offer efficient solutions for numerous applications. For position detection in linear drives, the BES inductive sensor does not return an absolute position, but detects the change of position by counting pulses. This makes the Balluff sensor solution more cost-effective than, for example, a rotary encoder.

    The features

    • Extended switching distance
    • Extended temperature range
    Energy, solar energy, guiding photovoltaic modules

  • Electrode monitoring in the electric arc furnace

    Electrode monitoring in the electric arc furnace

    The solution

    Sensors for detecting color and contrast support the positioning of electrodes in the arc furnace. The sensor, which is protected in the gripper, checks whether it has been gripped correctly using color markings on the electrode – with absolute reliability and at various temperatures.

    The features

    • Software allows for simple configuration and visualization
    • Any number of colors, even the slightest shades, can be detected and differentiated even with changing object temperature
    • Rugged metal housing

  • Sheet feeding for the coil

    Sheet feeding for the coil

    The solution

    BUS ultrasonic sensors from Balluff are precision all-rounders. They detect sheets on rolls and coils and regulate the correct material feed on the dancer roll according to the sheet sag. In this way they ensure the correct roller drive and that the sheet tension is always perfect.

    The features

    • Contactless detection
    • Reliable under demanding requirements and harsh conditions

  • Quality control at the finishing system

    Quality control at the finishing system

    The solution

    Fulfilling your highest quality requirements: the BFS color sensor from Balluff is unrivaled in inspecting sheet and plate finishes. It detects even the slightest color nuances and reliably registers whether a sheet leaves the plant polished or unpolished. Even temperature fluctuations won't keep it from correctly and reliably distinguishing the finished pieces.

    The features

    • Distinguishes any number of colors
    • Three digital outputs and a serial interface for performing evaluations (direct output of Lab color values)
    • Large sensing distance up to 400 mm
    Quality control at the finishing system

  • Centering wafers

    Centering wafers

    The solution

    You can reliably ensure alignment of the wafer on-the-fly using two Micromote through-beam sensors. Their high-precision signals make it possible to calculate the offset for the ideal line when the switching for both through-beam sensors is not simultaneous. Due to our Microspot technology, you can correct the wafer, since it precisely detects the sharp wafer edges.

    The features

    • Extremely focused LED light spot with outstanding homogeneity
    • Smallest, space-saving form factors
