Displays the maximum pressure reached up to that moment.
The size of the port on the switch body with which a device can be connected.
The switch output that uses the PNP transistor for output.
The condition in which the display is turned off to reduce current consumption.
A pressure-detecting part of a pressure-detecting element.
The setting of pressure to determine the point at which the Pressure switch
turns on and off.
The pressure beyond which the Pressure switch will be damaged.
The pressure range in which the Pressure switch meets the specifications.
Values outside of this range can be set if they are within the set pressure range,
but cannot be guaranteed to meet the product specifications.
The value currently displayed.
For example, when the displayed value is 1.000,

is 5% of 1.000, while for a displayed value of 0.800 it will be 0.04.
Reproducibility of the displayed value for pressure and ON-OFF output
operating point when the pressure changes.
The difference between the ideal ON voltage and the actual voltage when the
switch output is on. It depends on present load current and ideally should be
"0".
Refer to "Indication resolution".
The elapsed time until the ON-OFF output begins operating, since the pressure
supplied to the Pressure switch has reached the set value. Generally, the
shorter the response time, the better the performance.
The switch output operation in which the switch is turned on when pressure
equal to or less than the set value is detected. In the (hysteresis mode) window
comparator mode, it indicates the operation in which a switch is turned on when
pressure is outside the switch output range (n1L to n1H or n2L to n2H).
(Refer to "List of output modes" on page 30.)
A type of chattering.
Refer to "Function selection mode".
The pressure range within which the switch output can be set.
A Pressure switch whose settings are copied to when using the copy function.
Alternatively called "ON-OFF output".
Function to change the unit in which the value of pressure is displayed. Only a
product with this function can change the unit. A product with Units selection
function cannot be purchased if it is used within Japan. Pressure is indicated
only by SI units in Japan.
The part of the Pressure switch which is in contact with the detected fluid, such
as a pressure sensor, seal, or fitting.
An output type which holds the output when the pressure is within a certain
range. (Refer to "List of output mode" on page 30.)
The ability to withstand a voltage applied between an electrical circuit and the
body. If more voltage is applied to the product, the product may be damaged.
(voltage mentioned here is not power voltage to activate the product).
The function which can adjust the displayed pressure value to "0".
