Airtac DMSG Electronic Sensor DMSG-NC08
The AirTAC Airtac DMSG Electronic Sensor DMSG-NC08 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. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-NC08
The DMSG-NC08 is an electronic solid-state switch for AirTAC cylinders with the piston magnet option. The N output letter means NPN 3-wire, powered from 5-30 V DC, and general protection is IP64. The trailing C08 token in the wiring position is a connection code that the standard catalogue does not spell out - we will confirm its exact termination from the datasheet on request.
What is fixed is the circuit behaviour: a solid-state contact that never bounces, wired with the polarity discipline that any 3-wire NPN device demands. The G profile letter is purely a fit code for the cylinder's sensor groove, so verify seating against your cylinder series, and fit the magnet-equipped piston or the switch has nothing to detect.

| DMS | Electronic cylinder switch — electronic (solid-state). |
|---|---|
| G | Profile letter: the mounting / groove type that fits a particular cylinder body. This family offers E, G, H, J. It is a fit code, not a performance grade. |
| N | Output: NPN 3-wire. Blank is 2-wire, N is NPN 3-wire, P is PNP 3-wire. |
| 08 | See datasheet. 020 / 030 / 050 / 100 are 2 / 3 / 5 / 10 m flying leads; M08 and M12 are M8 / M12 connector versions. |

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-NC08 Is Used
Fixture clamping status
Reports closed-and-clamped on a machining centre fixture cylinder so the control releases the spindle only when safe.
Compact cabinet routing
NPN 3-wire wiring suits tight electrical cabinets where separate signal and supply conductors simplify terminal layout.
Stroke verification in testing
Bench rigs use the switch to verify actuator travel on hydraulic test stands adapted with AirTAC pneumatic positions.
Is the Airtac DMSG Electronic Sensor DMSG-NC08 the Right Switch?
The NPN 3-wire output is the choice for PLC sinking inputs where signal quality matters more than wire count. Because the C08 termination is undocumented, ask us for the datasheet page before planning your panel side - we will not guess it for you. If you already know you want an M8 connector instead, the M08-coded siblings of this switch give a defined plug. The G profile must match the groove; the cylinder must carry the magnet.
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-NC08 FAQ
Electronic solid-state type, NPN 3-wire output, 5-30 V DC supply, IP64 protection. The wiring is coded C08, a connection code we will confirm from the datasheet rather than assume.
The G is a fit code for the cylinder's sensor groove, not a performance grade. The catalogue does not map G to specific series in our data, so confirm against your cylinder - and it must be the magnet-equipped version.
