High Reliability Superior to That of Non-Contact Type by Employing Double and Triple Barriers. Best Suited for Heavy Duty Application due to Outstanding Environmental Immunity

Features
  1. Complete floodtight and gas resistance:Outstanding environmental immunity is assured by employing floodtight, corrosion-resistant construction and through use of hermetically sealed contact.
  2. 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.
  3. Powerful contact:Inductive load of 115VDC 0.3A can be directly controlled without using an amplifying relay or protective circuit.
  4. 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.
Typical Applications
  • Steel plant equipment
  • Large-size transportation machinery
  • Material handling equipment
  • Cement producing equipment
Types with # such as PSKU-#R25A can vary depending upon the contact arrangement 1NO [100], 1NC [010], 2NO [200], 2NC [020], 1NO1NC [110]
