| This article states the basic information about the electromagnetic relays, and also lists the principles of selecting them and cautions about applications.
Generally the parameters in the instructions in the catalogue are the measured initial values under the standard, which are as follows, unless otherwise stated.
1) temperature: 15℃ to 35℃
2) relative humidity: 25% to 75%
3) air pressure: 86kPa to 106kPa
Generally the drawings stated in the catalogue is the first quadrant projection way as shown in figure 1, unless otherwise stated.
