NPM8 Series Mental PushButton IP65/IP67 Industrial Control Circuit
Pushbutton Switch
Product Description:
The NPM8 series mental pushbuttons are suitable for use in
industrial control systems, instruments, household appliances, and
other applications where alternating current (AC) is 50 Hz (or 60
Hz), with a rated operating voltage of AC 220 V or less, or direct
current (DC) operating voltage of DC 110 V or less. They can be
used to control the electrical circuits of contactors, relays, and
other signaling devices. Pushbuttons with indicator lights are also
applicable for lighting signal indication purposes.
Meet the standard: GB/T14048.5,IEC 60947-5-1.

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 NPM8 series mental 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.
