New Products: Float switch

The MP3000 Switch Series, with a floater actuator, accurately determines when specified liquid levels are reached. The floater consists of a polypropylene ball mounted on a stainless-steel level actuator that can trigger a signal as an input for a PLC or directly switch power up to 6 A. The chemically resistant ball has a 2-in. diameter and a 210°F working temperature and can withstand 250°F for a short period. While the MP300 switches mount outside the liquid contents, they have a sealed, IP67 design. The switches can be wired as a changeover switch or with a simple NO or NC circuit, operate to 400°F under EN61058 or 200°F under UL 1054, depending on the type of cable used, and have a 250-Vac/6-A power rating under EN61058 and UL 1054.
