    Overview

    High temperature coil spring limit switch has an automatic reset function and is available with spring top diameters of 6.5 mm or 1.2 mm. SUCH coil spring limit switch adopts a fully enclosed 1NO + 1NC contact design for reliable switching performance. The standard rated specification is 5A/220VAC, and other voltages such as AC 120V, AC 380V, DC 12V, and DC 48V can be customized. The switch is designed to operate in extreme environments with temperatures up to 350℃ (622℉) and can function reliably in high-humidity conditions with a tolerance of ≤95% RH.

    Feature

    • Suitable for use in high-temperature environments and provides reliable performance.
    • The coil spring limit switch has automatic reset function.
    • The fully enclosed contact structure maintains stable and durable performance even in high humidity environments.

    FAQ
    ❯

    A limit switch operates when a mechanical actuator is pressed or moved by an object, causing the internal contacts to open or close and send a signal to the control system.

    ❯

    Limit switches are widely used in industrial machinery, automation equipment, elevators, conveyor systems, and safety control applications.

    ❯

    When selecting a limit switch, factors such as operating environment, actuator type, mounting method, and application requirements should be considered.
