ISG Mechanical Pressure Switch, AC/DC, IP44 Dripproof
ISG is a mechanical pressure switch for applications where an electronic switch is unsuitable, or when it is desirable to trigger an electrical device when the set point is reached. ISG offers excellent repeatability and adjustable hysteresis. The circuit can be wired normally open or closed, with either AC or DC voltage for a range of inductive or non-inductive loads. Choose bronze/brass or 316 stainless steel wetted parts to monitor vacuum for a range of gases and liquids. CE compliant option, with IP40 or IP44 enclosure rating. Model with indicator light also available.
- Mechanical pressure switch suitable for various gases and liquids
- 3 pressure ranges: 0.02-0.3, 0.05-0.7, 0.1-1.0 MPa
- CE-compliant rated voltage: 110 VDC/220 VAC or less
- Switch output is applied AC/DC circuit voltage for standard industrial loads
- Repeatability: ±0.006 to ±0.02 MPa (see pressure ranges) or ±2 kPa (vacuum option)
- Hysteresis adjustable by pressure range

1. Bellows assembly is available for mainte-
nance. When replacing other parts, please
contact SMC, since it cannot be repaired by
user.
Order Bellows assembly with the part number
as follows:

1. Never use in an environment, where
flammable fluids or gases are used. Since this
product is not explosion-proof and may trigger
an explosive disaster.
1. Select the model taking into consideration the
material suitable for the operating fluid. Type
of operating fluid is limited by the material of
wetted parts. Please contact SMC for materi-
als not specified.
1. Mounting is possible in either horizontal or
vertical orientations.
1. In the case of using switch in any liquid, install
a water hammer or surge reducer to prevent
the damage to switch caused by surges or
pulsation pressure.
1. Do not have the internal wiring attached to the
connection lever for switch operation. It may
malfunction.
1. Set the pressure by adjusting the setting
pressure adjusting bolt to the right to increase
and to the left to decrease.
2. Adjust the hysteresis with hysteresis adjusting
bolt. In case of switch with scale plate, adjust
the hysteresis with a flat head screwdriver
tightening the adjusting bolt in the thread cap.
Turn to the right to increase and to the left to
decrease.
3. Hysteresis must be within the specified range
in this catalog, operation may be unstable
when activated out of the specified range.
4. Scale plate is only for reference. Use the
gauge to get the correct pressure value.
5. Set pressure scale at the value of the pres-
sure increase.
Be sure to read before handling.
Refer to pages 16-14-3 to 16-14-4
for Safety Instructions and
Common Precautions on the
products mentioned in this catalog,
and refer to pages 16-1-11 to 16-1-
13 for Precautions on every series.
1. The grommet size of open type switch is ø17.
It is possible to connect the electric piping
1/2B without grommet.
2. Max. diameter of an electric cord usable for
bulb gland is shown as below.
