3 71 PRESSURE SWITCHES & SENSORS For further information www.imi-precision.com 18D Electrical connection acc. to DIN EN 175301-803, form A - connector included in the scope of supply. The Ex approval refers to the pressure switch in combination with the supplied plug. *1) Setpoints should be ideally in the middle of the switching pressure range. Reference pressure = atmospheric pressure. Switching pressure must not exceed the indicated values. *2) Max. values.
