PF Relays

PF Relays Cautions for Use

1.Usage, transport and storage conditions

1.Temperature: –40 to +85°C –40 to +185°F

2.Humidity: 5 to 85% RH (Avoid freezing and condensation.)

The humidity range varies with the temperature. Use within the range indicated in the graph below.

3.Atmospheric pressure: 86 to 106 kPa

Temperature and humidity range for usage, transport, and storage

4.Condensation

Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of the relay insulation.

5.Freezing

Condensation or other moisture may freeze on the relay when the temperatures is lower than 0°C 32°F.
This causes problems such as sticking of movable parts or operational time lags.

6.Low temperature, low humidity environments

The plastic becomes brittle if the relay is exposed to a low temperature, low humidity environment for long periods of time.
