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 LAY39 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.
●The cutout dimensions for the mounting panel: Φ22.3 0+0.4mm.
