Position and speed detection for electric drives

Balluff offers a broad array of simple on/off presence detection sensors in a wide variety of form factors and sensing principles.

In highly dynamic applications where each gram of weight savings means an improvement in acceleration rates and energy efficiency, Balluff's expertise in micro-optical, mini-inductive, and mini-magnetic sensors offer flexible alternatives to machine designers.

Application examples

  • Measure speed and detect direction of rotation

    Operation free of interference with high uptime

    The solution

    The extended temperature range of the inductive BES standard sensors ensures operation free of interference: They measure shaft speeds in the plant construction at temperatures down to –40 °C. Two sensors are sufficient for measuring the speed, detecting the direction of rotation and reliably protecting the equipment from overspeed.

    The features

    • Easy installation thanks to high switching distance
    • Operation free of interference thanks to extended temperature range
    • High equipment uptime thanks to contact-free detection
    • Insensitivity to contamination means no additional protection measures are required
    Measure speed and detect the direction of rotation of shafts in plant engineering using inductive standard sensors

  • High speeds directly on the motor shaft

    Precise, reliable and compact

    The solution

    BML S1F magnetic encoders precisely and reliably measure the speeds of the drive shaft directly on the motor. Their narrow form factor allows the existing motor design to remain compact.

    The features

    • Extremely accurate, even at very low speeds
    • Low-wear and service-free thanks to contact-free working
    • SIN-/COS- or ABZ interface
    Measure high speeds directly on the motor shaft with the BML S1F magnetic encoder

  • Measure slow and fast speeds

    Extremely accurate detection thanks to wear-free measurement systems

    The solution

    Our BML magnetic encoders detect both the direction of rotation and the correct shaft position using reference points. They are extremely accurate at all rotational speeds.

    The features

    • Wear-free thanks to contact-free working
    • High plant safety thanks to the wide speed range
    • Fast commissioning through reference points

  • Detect individual positions

    Compact form factors fit in small spaces

    The solution

    Thanks to their compact design, Balluff's high-performance inductive micro-sensors can also be integrated into places where standard inductive sensors won't fit. Inductive micro-sensors can be used for end-of-travel limit switches and for detecting index positions on linear and rotary drive mechanisms.

    The features

    • Design flexibility for single or multi-axis linear drives
    • Small physical sizes enable high-density, compact implementations
    • Low mass enables high acceleration rates, eliminates weight as a design obstacle
    Detect individual positions in linear units

  • Spindle position detection

    End position detection with mini-sensors

    The solution

    Inductive mini-sensors are ideally suited for end position detection in spindle drives. Their flat, rectangular form factor fits easily into most designs.

    The features

    • Compact, easy-to-integrate designs
    • High quality components with proven reliability
