"MUT 7.030.01522 7.004.00306 DIFFERENTIAL WATER PRESSURE SWITCH SFS-105-M1 THREAD 1/4G MICRO BIPOLAR
10A 260V IP54
PN 10 BAR
PN DIFFERENTIAL MAXIMUM 5 BAR
MAIN FEATURES The SFS differential pressure switch closes, or deflects, an electrical contact when the differential
of pressure applied to the two outlets reaches the upper calibration value (intervention) and restores it when it
drops below the lower calibration value (release). It can be used in plumbing systems where control is necessary
that the pressure difference between two points does not exceed or fall below a certain value. A pair
of permanent magnets placed in mutual repulsion, one inside the body of the pressure switch and one external, replaces the classic one
solution with shaft and O-ring seal, allowing a notable increase in the reliability and life of the pressure switch."
