Standards & Certifications
The NR01 Series rotaries have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.
General Specifications
Note: Values are determined by NKK's individual specification tests in a controlled environment, and do not certify that the product
supports simultaneous multiple conditions.
