Product Feature:
•Design: The buttons feature a fully plastic housing with an attractive appearance and a well-designed structure.
•Protection: Equipped with rubber cable glands and waterproof seals, providing good dust and water resistance.
•Performance:
•Most buttons have automatic reset functionality, except for the "start", "general stop", circuit master switch "ON", and "self-locking" buttons.
•They include mechanical interlocking mechanisms for forward and reverse control, which simplifies the circuit and effectively protects the circuit and equipment during operation.
These buttons are designed for reliable operation in harsh outdoor environments and are equipped with protective features to ensure safe and effective control of equipment.
Operating Conditions and Environmental Suitability:
●Ambient temperature is -5℃~+40°C, the average temperature during 24 hours couldn't exceed +35°C.
●Altitude: ≤2000m.
●Atmosphere condition: Relative humidity of the atmosphere couldn't exceed 50% when the highest temperature is +40°C; much higher relative humidity is allowable under the condition of lower temperature, for example, when the temperature reaches +20°C, the relative humidity is up to 90%, taking into account the condensation that may occur on the product surfaces due to temperature changes.
●Pollution grade: 3.
●Installation category: II.
●The NP3 series pushbutton should be installed in an environment without significant shaking, impact, vibration, and without exposure to rain or snow.
●It should be installed in an environment without the risk of explosion and where the medium does not contain gases that could corrode metals or destroy insulation, nor excessive dust.
