Airtac DMSE Electronic Sensor DMSE-N030
The AirTAC Airtac DMSE Electronic Sensor DMSE-N030 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
AirTAC's DMSE-N030 is a solid-state electronic switch from the DMS range for cylinder position feedback. The code spells out an NPN 3-wire output, a 3 m flying lead and the standard build rated IP64; the supply window is 5-30 V DC. It detects the magnet built into the piston of an AirTAC cylinder fitted with the magnet option - without that magnet the switch stays silent.
The extra metre of lead over the 2 m version is a specification choice, not a delivery matter: it lets you route around guards and reach a distant junction box without joints or extensions. Because the output is transistor-based, cycling is chatter-free versus a reed contact - handy on high-cycle machinery. Check that the E profile seats in your cylinder's groove before ordering.

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 Is Used
Palletiser pusher arms
Confirms pusher arm extension on a palletising cell; the 3 m lead reaches the junction box on the machine frame without extensions.
Bottle diverter confirmation
Case diverter cylinders on a bottling hall conveyor report retracted position to the line PLC before bottles release.
Fatigue test rig travel
Marks end of travel on the actuator of a materials fatigue test rig, logged by the rig's data system.
Is the Airtac DMSE Electronic Sensor DMSE-N030 the Right Switch?
If your panel runs sinking inputs, this NPN 3-wire switch is the direct match; European-style sourcing inputs call for the P version instead. Compare lead options: 2 m suits short local runs, this 3 m lead clears guards and machine frames, and 5 m, 10 m or an M8/M12 connector exist for panel-mounted I/O. Electronic switching avoids the contact bounce of a reed type, which matters on rapid cycling. Fit check: the E profile must match the sensor groove on your cylinder, and the piston needs the factory magnet option.
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 FAQ
This is an electronic (solid-state) switch with an NPN 3-wire output, a 5-30 V DC supply and IP64 protection on the general build. The 030 in the code means a 3 m flying lead - a longer cable run straight out of the catalogue, with no joints needed.
DMS and EMS models are solid-state: DC powered, no contact bounce, and the 3-wire types offer a polarity-defined NPN or PNP output for PLC inputs. The CMS family is a reed switch: a mechanical contact, no polarity, and a very wide 5-240 V AC/DC range, but with finite contact life on fast cycling. Choose by your circuit voltage and input type.
