Digital, Miniature Pressure Switch with Display
PSW-1110
• Compact, 1" cube that fits
practically anywhere
• 8 selectable pressure units
• Two fully-programmable PNP
digital outputs
• Bright, multi-colored, 4-digit
display and LED indicators for
high readability
• Two pressure port locations one horizontal and one vertical
- for easy installation
These miniature pressure switches provide
PNP output switch control for non-corrosive
gasses. The PSW-1110 features a bright 4digit, 7-segment, programmable display that
makes it easy to see the current pressure.
The ultra-compact size and multiple pressure
port orientations make this unit easy to install
practically anywhere. There are both a
horizontally and vertically oriented pressure
ports.
The PNP outputs are fully programmable, and
the user can also select one of eight pressure
units: psi, bar, kg/cm2, KPa, MPa, inHg, cmHg,
and Atm. There are four options for output
modes. The main options are hysteresis and
window modes, and each of those have high
and low methods of actuation.
The PSW-1110 is also available with the
following options: additional pressure ranges,
NPN outputs, alternate pressure port thread
types, and with liquid media compatibility.
Contact us if you would like to learn more
about these options.

Digital, Miniature Pressure Switch with Display
PSW-1110
There are two main types of output modes for the digital output - hysteresis mode and windowed
mode.
Hysteresis mode has two types of actuations, active low and active high, as shown on the left side of
the Output Modes figure below.
Active Low: Turns the output off when the pressure has reached the high setpoint (green line). The
output remains off until the pressure has dropped below the low setpoint (blue line).
Active High: Turns the output on when the pressure has reached the high setpoint. The output remains
on until the pressure has dropped below the low setpoint.
Windowed mode also has two types of actuations, active low and active high, as shown on the right
side of the Output Modes figure below.
Active Low: Turns the output off when the pressure is between the high setpoint (green line) and the
pressure low setpoint (blue line).
Active High: Turns the output on when the pressure is between the high setpoint (green line) and the
pressure low setpoint (blue line).

Accessories
Our product accessories section contains a selection of mounting accessories.
Vertical or horizontal brackets are available, made for easy mounting to another
surface; the sensor has two threaded mounting holes on the back side that either
bracket screws into. Panel mounts are also offered and suitable for a wide range for
the panel cutout due to spring loaded clips molded into the housing.
The PSW-1110 is also available with the following options: additional pressure
ranges, NPN outputs, alternate pressure port thread types, and with liquid media
compatibility. If you would like to learn more about these options or require further
customization of this design, contact us using the chat function or by emailing us at
