Product Features
Dual-row LCD displays measured pressure and the selected setting, with configurable red/green backlighting.
Two switching outputs can each use easy, hysteresis or window-comparator operation, with normally open or normally closed selection.
Selectable pressure units, display refresh time and output response delay support different machine-control requirements.
The setting-lock and zero-adjustment functions are available from the front buttons.
The NPN version supports the catalog’s master/slave parameter-copy function.

Electrical Connections
Parameter
Details
Brown wire / positive supply
Connect to DC supply positive within the rated supply range.
Blue wire / negative supply
Connect to DC supply negative.
Black wire
Switching output 1.
White wire
Switching output 2.
Load connection
For NPN output, connect the load between positive supply and the output; the output sinks current.
Protection and restart
An output load above 100 mA activates short-circuit protection. Remove the fault and restart as directed in the catalog.

Basic menu
Hold SET for 2 seconds from measurement mode. Set the output mode, NO/NC behavior, response delay and backlight behavior.
Advanced menu
Hold SET for 4 seconds from measurement mode. Hold SET for 2 seconds to return to measurement mode.
Backlight selection
Red with output and green without output; green with output and red without output; always red; or always green.
Advanced display settings
Choose the lower-row setting value, blank display or unit; select display update time and hysteresis.
Advanced functions
Power-saving/backlight setting, backlight trigger OUT1/OUT2/AND/OR, copy setting where supported, and factory reset.
Zero adjustment
Press the up and down buttons together.
Setting lock
Up + SET locks the settings; down + SET unlocks them. LCK is displayed when a button is pressed while locked.
Switching Modes
Parameter
Details
EASY mode
A single setpoint is used with the selected hysteresis. In the normal output diagram the output switches on above the setpoint plus hysteresis and off below the setpoint.
HYS mode
Separate upper and lower thresholds set the switching band. In the normal output diagram the output turns on above the upper threshold and off below the lower threshold.
WCMP window-comparator mode
The normal output diagram is active within the selected lower/upper pressure window and inactive outside it, with hysteresis at the boundaries.
NO / NC selection
Each output can use normally open or normally closed behavior. The selected logic determines whether the indicated switching state is inverted.
NPN Parameter Copy
Only the NPN type supports the copy function. With power off, connect the master and slave as shown in the catalog’s dedicated copy diagram, including the master pin 2 to slave pin 3 connection. Select CP-M for the master and CP-S for the slave, then carry out the copy sequence. Check the completion display; if copying fails, repeat the sequence. Power off before disconnecting the copy wiring and restarting normal operation. Use the connection and pin labels in the diagrams; the ordinary operating circuit and temporary copy circuit serve different purposes. The published copy diagram and normal operating circuit use different negative-wire color labels. Confirm the temporary copy wiring for the supplied unit with AirTAC before making that connection; do not infer it from the wire color alone.
Mounting Accessories — Ordered Separately
Parameter
Details
F-DPSEB
Panel-mount adapter and front protective cover for terminal and prewired/grommet versions; panel-frame dimension 31 mm, tolerance +0/−0.5 mm, in both directions.
F-DPSLB
Mounting bracket for the DPS sensor; the 2025 drawing shows 29.6 mm upright width, 24 mm upright height, two Ø3.2 mm mounting holes and 1.6 mm plate thickness. The bracket is an installation accessory and is not included merely by ordering the sensor.
Assembly sequence
Assemble the front cover first, then the rear cover, as shown in the panel adapter drawing.
Installation and Operating Notes
Do not drop the sensor or subject it to impact.
Do not apply more than 60 N tension to the cable.
Tightening torque at the pressure connection must not exceed 7 N·m.
Do not use corrosive or flammable gases or liquids.
Keep pressure within the specified range.
Turn the power off before wiring.
Avoid oil and solvent splashes.
Separate signal wiring from high-voltage cables and conduits.
After an output fault or overload, correct the cause before restarting.
Where transient pressure produces an unwanted response, select an appropriate response delay.
Dimensions and Mounting
Dimensions are in millimeters. The D version’s bottom feature is its electrical connector; the pressure connection remains the threaded connection shown at the rear. Mounting accessories are ordered separately.

Estimated Weight
Approximate engineering estimate: 85 g, excluding packaging. The calculation uses 43 g for the sensor body, an effective four-core lead allowance of 21 g/m for 2 m, and 0 g for an additional M8 connector, which is not part of this option. The lead allowance comes from a published 85 g versus 43 g comparison for a 2 m lead assembly on a similarly sized pressure switch; it is an allocated reference including that lead assembly’s connector, not a published AirTAC cable density. These are cross-model weight estimates, not AirTAC catalog or measured weights. Housing, connector, cable and thread differences are not individually weighed. No compatibility or technical equivalence is implied. Brackets, separately ordered extension cables and packaging are excluded.
