Airtac DMSE Electronic Sensor DMSE-N030-W
The AirTAC DMSE Electronic Sensor DMSE-N030-W is a genuine DMS magnetic position switch. It senses the magnet ring in a pneumatic cylinder's piston and signals when the piston reaches that point, giving a npn 3-wire output on 5-30 V DC with a 3 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSE Electronic Sensor DMSE-N030-W
The DMSE-N030-W is a solid-state electronic position switch from AirTAC's DMS range, built with an NPN 3-wire sinking output for direct connection to a PLC input card. It reads the piston magnet of an AirTAC cylinder fitted with the built-in magnet option and signals when the piston reaches the switch. The wiring code 030 gives a 3 m flying lead, the supply range is 5-30 V DC, and the general housing carries IP64 protection.
Because the output is 3-wire rather than 2-wire, the signal to the controller is cleaner - the switching element sits between the negative line and the output, so leakage into the input is minimal. The trailing -W on the model code is a factory variant we will confirm from the datasheet on request. The profile letter E sets the fit against the cylinder's sensor groove, so check it matches your cylinder body before ordering; exact seat confirmation is available from the datasheet.

We do not hold the full profile-to-cylinder-series table, so confirm the profile letter against your cylinder model before ordering — send us the cylinder part number and we will check the fit.
Which Family Do You Need?
- DMSElectronic, 2-wire / NPN / PNP, DC
- EMSMini electronic, 2-wire only, DC
- CMSReed contact, 2-wire, 5-240 V AC/DC
The split is electrical, not quality. Solid-state DMS and EMS are DC-only and suit modern PLC inputs; the reed-based CMS switches a much wider window, so it is the one for AC circuits, relay logic and older panels. The RW (IP68) option exists on DMS and EMS only.
| This switch | DMSE · NPN 3-wire · 5-30 V DC |
|---|---|
| Consider EMS | the mini 2-wire electronic switch for tight installations |
| Consider CMS | the reed alternative for AC circuits and voltages up to 240 V |
| Mounting parts | F-MQ (round body), F-ACT (tie-rod) |
Where the Airtac DMSE Electronic Sensor DMSE-N030-W Is Used
PLC end-of-stroke feedback
NPN 3-wire sinking output drops cleanly into a standard sinking PLC input card, giving unambiguous retract-position confirmation on automated assemblies without contact bounce to filter out.
Fixed-panel machine wiring
The 3 m flying lead reaches a control cabinet on a mid-size machine and can be trimmed in the panel, keeping the install tidy where an M8 connector stub would be unnecessary.
Pick-and-place station sensing
Mounted in the groove of a magnet-fitted AirTAC compact cylinder, the solid-state element tolerates the rapid, repeated clamping cycles of a pick-and-place head without mechanical contact wear.
Is the Airtac DMSE Electronic Sensor DMSE-N030-W the Right Switch?
Pick this model when your control system expects an NPN (sinking) input and you want the solid-state advantages: no contact bounce, fast repeated cycling and DC-only operation at 5-30 V. If your PLC input card is sourcing (PNP), step across to the -P variant instead; if you would rather wire it in series like a mechanical switch, the 2-wire DMS or the reed-type CMS is the simpler path. The 3 m flying lead is a cut-to-length specification choice - choose an M8 or M12 connector version instead if you need to unplug the switch for service. This unit needs a magnet-equipped cylinder (the -S magnet option) to sense anything. The E profile must match your cylinder's groove, so confirm the fit before you order.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (NPN 3-wire)
- ✓ Supply rail is 5-30 V DC
- ✓ Lead length or M8 / M12 connector
- ✓ Coolant or flexing? Use the RW version
Installation & Wiring Notes
- check The cylinder must carry a piston magnet — a plain cylinder cannot be sensed.
- check Slide the switch along the groove to the stop position, then lock it.
- check Keep the supply within 5-30 V DC.
- check Wire npn 3-wire to match the PLC input's polarity.
- check Keep the lead clear of moving parts; use the RW type where it must flex.
- check Rated IP64 — protect it beyond that rating.
Use the F-MQ bracket on round-body cylinders and F-ACT on tie-rod cylinders where there is no groove to seat the switch. Both are ordered separately from the switch. Switching distance and mounting dimensions come from the factory datasheet — ask us for the sheet that matches your cylinder.
Airtac DMSE Electronic Sensor DMSE-N030-W FAQ
It is an electronic (solid-state) DMS position switch with an NPN 3-wire sinking output. Supply voltage is 5-30 V DC, protection is IP64 (general type), and the wiring is a 3 m flying lead (code 030). The -W suffix is a factory special variant - confirm its exact meaning from the datasheet.
A 3-wire NPN output gives a cleaner signal to a PLC input than a 2-wire switch wired in series, because leakage into the input is smaller - but the input card must be a sinking (NPN) type. The E profile letter is a fit code that must match your cylinder's sensor groove, not a quality grade, so verify the seat against your specific cylinder series. The cylinder must also carry the built-in magnet option for the switch to detect the piston.
