Circuit Configuration and Ratings

Features and Specifications

  • Double-structured housing of Head & body, excellent stability to the high airtightness
  • Due to its high mechanical strength, it flexibly absorbs the unstable dog movement applied to the actuator and performs stable operation.
  • It has a structure that does not use adhesive or molding, and has high sealing properties and excellent stability.
  • Adopting a safe return system, exhibiting stable operating characteristics even after maintaining the switch on state for a long time.
  • Use highly corrosion-resistant stainless(sus) steel bolts and nuts.
  • Suitable for roof crane, large conveyor, industrial large-scale machine, outdoor plant etc,
  • Excellent in anti-corrosion and flame-retardant, excellent performance in environments such as petrochemical plants and gunpowder plants, power plants, oil tankers, LNG carriers, LNG carriers, offshore plants, chemical plants with corrosive acids and alkaline gases.
  • Exercise excellent operation characteristics in a state where the horizontal angle of the switch changes like the tip of the BOOM in a type that operates / returns the sensor when the load of the weight for the rope is released
