as WARNING and NOTE, will be followed by important safety
information that must be carefully reviewed.
Indicates a potentially hazardous situation
which could result in death or serious injury
if you do not follow instructions.
Specification
Safety Instructions (continue)
• Insert a noise filter (line noise filter, ferrite element or other element)
between the switching regulator and pressure switch when analog
output is used.
• Do not use with a corrosive or inflammable gas or liquid.
• Do not press the setting buttons with a sharp pointed object.
• Turn power on for 20 to 30 minutes before detecting fine pressure.
Initial drift of about ±1% occurs immediately after turning the power on.
• The direct-current power supply to combine should be a UL
authorization class 2 power supply based on UL1310, or a power
supply using a transformer which is class 2 based on UL1585.
• Only a pressure switch with UL mark on the body is UL approved.
• This pressure sensor is for use with air only. Please contact SMC if
the switch is to be used with other fluids.

• The Digital pressure switch with panel mount adapter
can be removed from panel by releasing the hooks at
the switch sides
as illustrated.
more than 24
Pressure switch
and Panel mount
adapter may be
damaged if not
released correctly.
• Make connection after turning the power off.
• Install the lead wire separately from the route for power cable or
high-voltage cable. Otherwise, malfunction may potentially result
due to noise.
• Be sure to ground Terminal FG when using a switching regulator
obtained on the commercial market. If the analog output is
connected to a switching regulator obtained on the market, switching
noise will be superimposed and product specification can no longer
be met. This can be prevented by inserting a noise filter, such as a
line noise filter and a ferrite element, between the switching regulator
and the pressure switch, or by using a seriespower supply instead of
a switching regulator.
Connector Connecting/Disconnecting
• When connecting the connector, insert it straight onto the pins and
lock the connector into the square groove in the housing unit
connector clicks.
• When disconnecting the connector, press the connector lever to
disengage the lever claw from the square groove. Then pull the
connector straight out.

Zero Clear Function
The displayed value can be adjusted to zero when pressure to be
measured is within ±70digits of the atmospheric pressure.
(The range of ±10% F.S.setting is different depending on the
individual product difference)
This function is useful because it enables the detection of pressure
fluctuations larger than a certain value without being influenced by
fluctuations of source pressure. Press continuously the
