Torque limiter height limit switch

Limit Switch, IP65 anti-roll switch (also known as wire rope anti-roll switch) , is used for lifting machinery wire rope anti-roll limit of an electrical automatic protection switch. When it is used with a proper weight weight, the up and down operation of the hook can be used to prevent the wire rope from overwinding, and the hook can rise and fall in a certain height. The product is reasonable in design and advanced in performance. Compared with other products of the same kind, the failure rate tends to zero, the utility model has the advantages of compact structure, flexible switch shift, safety and reliability, long service life, convenient installation, etc. . Technical Parameters: Voltage Rating: 12-380VAC/DC; Current Rating: 5A; GJ-3 Switch Contact: Normally closed without weight; Contact Material: Precious metal; Weight of external weight hammer: ≥1.70 kg Housing Material: Engineering plastic; working principle: to rely on the weight of weight hammer to make the trigger device in the open or closed state, when the hook pick up the process, once it exceeds the preset height, it will hit the hammer and make the weight of the hammer acting on the trigger device disappear. Then the trigger device will work, the control circuit will be broken and the hoist will stop working, so as to protect the hook head. Compared with similar products, this product has the advantages of dynamic safety protection technology LING first, compact structure, flexible and durable, sealing and waterproof, easy installation, etc. . Widely used in different industries around the world, including automotive, electricity, food and beverage, petrochemical, metallurgy, tobacco, aerospace, machinery, textiles, paper, printing, packaging, rail transport, logistics, cement building materials, shipbuilding, wire and cable manufacturing, mining and municipal industries, become the preferred brand trusted by users.
