Airtac DMSGS Electronic Sensor DMSGS-N030
The AirTAC Airtac DMSGS Electronic Sensor DMSGS-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 2-wire output on 10-28 V DC. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSGS Electronic Sensor DMSGS-N030
This DMSGS-N030 belongs to AirTAC's electronic DMS family: a magnetic piston position switch with an NPN 3-wire output for PLC input cards. Supply is 5-30 V DC, sealing is IP64 as standard, and the code ends in a 3 m flying lead that you can trim to suit the cable route. It reads the piston magnet of an AirTAC cylinder that carries the -S magnet option.
Because the output is solid-state there is no reed contact to bounce or wear, which suits cylinders that index thousands of times per shift. Mounting depends on the profile letter: G here must match the sensor groove of your cylinder, and the trailing S is an undocumented code position - we verify it from the datasheet when you enquire.

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 | DMSG · 2-wire · 10-28 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 DMSGS Electronic Sensor DMSGS-N030 Is Used
Filling head raise check
On a bottling filler, the lift cylinder of each filling head signals top position so the controller only opens valves when heads are fully up.
Panel wiring at mid length
The 3 m lead spans a typical machine-to-panel route in a control cabinet retrofit, trimming neatly at the gland plate.
Sortation gate lock
Gate cylinders on a parcel sortation loop confirm their lock position to the sorter PLC through this NPN input.
Is the Airtac DMSGS Electronic Sensor DMSGS-N030 the Right Switch?
Choose NPN (this code) when the PLC input sinks; choose PNP where the input card expects a sourcing signal. Reed CMS switches stay the answer for AC or mixed 5-240 V supplies, while this electronic type needs clean DC and correct polarity. A 3 m flying lead is the mid-length compromise; connector versions trade a little cost for plug-and-leave maintenance swaps. Keep the general IP64 for dry, oiled machine frames, or step to -RW for IP68 washdown duty. Fit check: profile G against your cylinder groove, magnet option fitted.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (2-wire)
- ✓ Supply rail is 10-28 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 10-28 V DC.
- check Wire 2-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 DMSGS Electronic Sensor DMSGS-N030 FAQ
This is an electronic, solid-state switch with an NPN 3-wire output, powered from 5-30 V DC and sealed to IP64 as standard. Wiring is a 3 m flying lead. Supply, output and IP change if you move family: a reed CMS takes 5-240 V AC/DC, and a -RW build lifts protection to IP68.
The reed contact in a CMS switch tolerates AC or DC up to 240 V but is mechanical, so it has finite life and can bounce. This DMS body is solid-state: DC only, polarity-aware, and cleaner for fast PLC counting. Send your cylinder series and we will check the G profile fit.
