    Product Description

    Explosion-proof limit switches of the DVG-MKV series are designed for switching electrical control and signaling circuits in explosive environments.
    Miniature switches are available in two designs:

    DVG-MKV switches are used in applications requiring reliable and accurate signal transmission, including for pumps and control systems. Switches must be installed in devices so that they are mechanically protected. The device is equipped with a 3-meter cable.

    The M-DVG-MKVK switch is designed for installation as an Ex component within equipment or a device. The end device requires additional certification. The M-DVG-MKVK switch is available in two versions: with and without an actuator, and comes with 5-meter cables.

    Advantages

    • Compact dimensions and weight for installation in hard-to-reach places.
    • Materials: body – impact-resistant plastic, contacts – silver, pusher/drive – stainless steel.
    • Reliable design.
    • Ensuring reliable signal delivery.
    • Easy to install and operate.
    • High degree of protection against moisture and dust IP66.
