  • Material Length Measuring Wheel Encoder | 100–5000 PPR | Ø38 mm | Push-Pull | 5–26 V | For Length and Speed Measurement

    Code: ES-GHW381

    Wheel-type rotary encoder designed for measuring material length, movement speed, and angle in industrial and technical processes. The integrated measuring wheel directly contacts the moving material or surface and generates pulses that accurately represent the travelled distance or speed. This solution is widely used in automated production lines, conveying systems, and in the textile, paper, plastic, cable, and packaging industries, where precise monitoring of the length or speed of moving objects is required.

    Functions

    Precise length measurement – the integrated measuring wheel directly contacts the moving material and generates pulses. The number of pulses precisely corresponds to the travelled distance.

    Real-time speed measurement – the encoder generates a pulse signal proportional to the movement speed, allowing the system to accurately determine the linear speed.

    Angle position detection – rotary technology allows determination of angular position or number of rotations.

    High-quality optical sensor – the optical operating principle ensures high accuracy and stable signal even in intensive industrial environments.

    ABZ phase signal – allows detection of rotation direction, accurate pulse counting, and positioning functions in automation systems.

    Wide resolution range – selectable from 100 to 5000 pulses per revolution, allowing the device to be used in both simple and high-precision systems.

    Applications

    In industry: cable and wire length measurement systems, packaging lines, textile and paper production, film and plastic manufacturing lines, metal strip processing equipment, transport conveyors.

    In automation and engineering: PLC-controlled length measurement systems, motion control solutions, production process monitoring, automated measurement stations.

    For electricians and technicians: automatic counter systems, speed sensor integration, machine modernization projects.

    For technical projects and developers: robotics projects, Arduino or other microcontroller projects, testing and prototype development.
