    High Temperature Limit Switch with Roller Plunger

    $148.15
    There are two types of roller plunger limit switch, the roller direction of the one is parallel to the mounting surface, and the other is perpendicular to the mounting surface. Roller plunger has automatic reset function. It is also high temperature limit switch with the fully enclosed 1NO + 1NC contact switches casting from high temperature resistant material. It can be used in the environment temperature 350℃ (622℉) and without being damaged by oxidation or pollution. The default rated current and voltage is 5A/220VAC. Other values are customizable, such as 3A/480VAC, 0.8A/120VDC, etc.

    Note:

    1. Power factor of inductive load is above 0.4 (AC). The time constant is below 7ms (DC).
    2. The inrush current of lamp load is 10 times that of steady state current, and the inrush current of motor load is 6 times that of steady state current.
