Limit Switches

Specifications & Features


  • Complete flood tight and gas resistance:
    • Outstanding environmental immunity is assured by employing flood tight, corrosion-resistant construction and through use of heretically sealed contact
  • Long-term maintenance free:
    • This is achieved through the combination of the actuator exhibiting high mechanical strength as well as internal vane-action magnetic proximity switch featuring high electrical reliability, assuring long-term maintenance-free operation
  • Powerful contact:
    • Inductive load of 115VDC 0.3A can be directly controlled without using an amplifying relay or protective circuit
  • No contact chattering:
    • Since large actuator movement is considered in design, the switch is not ill affected by operational shock or vibration. Therefore, electrical circuit can be simplified
