22mm 30mm NP2 Series IP40 IP65 Push Button Industrial Control Circuit Pushbutton Switch
22mm 30mm NP2 Series IP40 IP65 Push Button Industrial Control Circuit Pushbutton Switch
Product Description:
The NP2 series pushbuttons are designed for industrial control circuits operating at an alternating current (AC) frequency of 50 Hz or 60 Hz, with a nominal working voltage up to 415 V AC, and a direct current (DC) working voltage up to 250 V DC. These buttons are used to control electromagnetic starters, contactors, relays, and other electrical circuits. Buttons with indicator lights are also suitable for the light signal indication occasions.
Meet the standard: GB/T 14048.5.

Product Feature:
•Panel Installation: The series includes buttons with panel diameters of Φ22 and Φ30, along with button control boxes, suitable for different installation scenarios.
•Protection Rating: The standard protection rating is IP40. If customers need customized IP65, please contact the manufacturer.
•Modular Structure: The buttons feature a modular design, allowing for flexible and convenient installation and maintenance.
•Separate Contacts: Normally open (NO) and normally closed (NC) contacts are electrically isolated from each other.
•Terminal Screws: Terminal screws are M3.5 in size, with a recommended tightening torque of (0.8 to 1.2) N·m.
•Contact Group Limit: Longitudinal series connections should not exceed two contact groups, too many contact groups will cause the increase of the operating force. For special requirements, users should consult the manufacturer.
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 NP2 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.
•Installation Dimensions:
For Φ22 panel-mounted buttons:
•Installation hole diameter: Φ22.3 0+0.4 mm
•Metal head style: suitable for panels 1 mm to 6 mm thick
•Plastic head style: suitable for panels 1 mm to 4 mm thick
For Φ30 panel-mounted buttons:
•Installation hole diameter: Φ30.5 0+0.5 mm
•Suitable for panels: 1 mm to 3 mm thick
These buttons are designed for reliable operation in industrial control applications and provide flexibility in installation and customization options.
