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
- Complete floodtight and gas resistance: Outstanding environmental immunity is assured by employing floodtight, corrosion-resistant construction and through use of hermetically 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.
Types with # such as PSKU-#R25A can vary depending upon the contact arrangement 2NO , 2NC , 1NO1NC
