Airtac DMSG Electronic Sensor DMSG-N030
The AirTAC Airtac DMSG Electronic Sensor DMSG-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 DMSG Electronic Sensor DMSG-N030
The DMSG-N030 is a solid-state electronic magnetic position switch from AirTAC, built with a 3-wire NPN output. It clips into the sensor groove of an AirTAC cylinder fitted with the magnet option and signals the controller when the piston reaches it. This version comes on a 3 m flying lead, runs from a 5-30 V DC supply, and carries IP64 protection on the general housing.
Because the output stage is NPN, the switch sinks current into the PLC input, so your input card must be a sinking type - knowing that up front avoids rewiring at commissioning. The G in the code is a fit code that selects which cylinder groove the body seats in; check it against your cylinder and confirm the exact match 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 | DMSG · 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 DMSG Electronic Sensor DMSG-N030 Is Used
Pick-and-place confirmation
Clipped into the groove of a magnet-outfitted AirTAC cylinder on a small-parts picker, the NPN output tells the robot controller the gripper has fully retracted.
Diverter gate interlock
Confirms to the line PLC that a gate cylinder on a carton conveyor has reached full extension before the next box is released onto the belt.
Sinking PLC input wiring
Sinks current into a 24 V DC sinking input module, connecting directly to the controller with no interposing relay.
Is the Airtac DMSG Electronic Sensor DMSG-N030 the Right Switch?
Pick this electronic DMS over a CMS reed switch when the circuit is DC and you want switching with no contact bounce during fast cycling. A 3-wire NPN hookup hands the PLC a cleaner edge than a 2-wire series connection. The 3 m flying lead can be trimmed on site; if you plan to unplug the sensor during service, an M8 or M12 connector version is the better choice. Remember the cylinder must carry the built-in magnet option, and the G profile has to match its groove.
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 DMSG Electronic Sensor DMSG-N030 FAQ
It is a solid-state electronic switch with a 3-wire NPN output, powered from a 5-30 V DC supply, connected through a 3 m flying lead. The general housing is rated IP64.
An NPN 3-wire output sinks current, which suits PLC input cards wired for sinking signals and gives a clean switching edge. A 2-wire unit wires in series like a mechanical contact but passes a small leakage current. Match the output to your input card before ordering.
