explosion proof type and stainless steel type Rotary Series limit switch
MLS300-S Rotary Series Limit Switch（Stainless Steel）
MLS Series Limit Switch is consistent with IP Protection standard, ISO5211 standard and Namur standard. The shell mainly include impact type, standard type, explosion proof type and stainless steel type; Mechanical switch, proximity switch are selectable for switch specification, which provide users with safety, high-quality and reliable automatic products.
MLS300-S series limit switch is used for indicating switch position locally and output of switch signal remotely of automatic valve. The shell material is SS316L. Designed with explosion-proof structure, suitable for ExdIICT6 standard, the products are widely used in petroleum, natural gas and other industries.
Characteristics
