    Overview

    Waterproof limit switch is rated at 5A (125VAC) and 3A (250VAC) and features an IP67 protection rating, making it suitable for harsh environments. SUCH limit switch operates at speeds ranging from 1 mm/s to 1 m/s with an electrical operating frequency of up to 30 operations per minute, and offers an electrical life exceeding 200,000 cycles. The contact resistance is ≤15mΩ (initial), and it is designed to operate reliably in temperatures from -10°C to +70°C (without icing) and in humidity levels below 95% RH.

    Feature

    • Fully sealed potting process with special encapsulation, providing IP67 waterproof, oil-resistant, and dustproof performance without foaming or delamination.
    • One-piece die-cast aluminum alloy housing ensures high strength, durability, and easy installation for versatile applications.
    • High-quality heat-resistant cable (approx. 1 meter, customizable) offers reliable and long-lasting performance.
    • Thickened silver contacts deliver excellent conductivity, low resistivity, and arc-free durability.

    Explanation of parameters:

    OF means operating force, the force that must be applied to the drive rod in order to move from the free position to the operation position.

    RF means release force, the force that must be applied to the drive rod in order to move from the total travel position to the return position.

    PT means pretravel, the distance the drive rod moves from the free position to the operation position.

    OT means overtravel, the moving distance or moving angle of the drive rod from the operation position to the full stroke position.

    MD means movement differential, the moving distance or moving angle of the drive rod from the operation position to the return position.

    OP means operating position, at which the external force is applied to the drive lever to make the movable contact just operating from the state of the free position.

    FAQ
    ❯

    The waterproof design helps protect internal components from moisture, dust, and contaminants, improving reliability and extending service life.

    ❯

    Ensure the switch is mounted securely in a stable position and aligned properly with the moving part so it can be actuated smoothly without excessive force.

    ❯

    Select a location where the switch can be triggered reliably, avoiding misalignment, vibration, or impact that could affect performance.
