Airtac DMSG Electronic Sensor DMSG-PC12
The AirTAC Airtac DMSG Electronic Sensor DMSG-PC12 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 pnp 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-PC12
AirTAC's DMSG-PC12 is a solid-state magnetic position switch delivering a PNP 3-wire signal from a magnet-fitted cylinder piston. It runs on 5-30 V DC, meets IP64 as a general-type unit, and its wiring position carries the code C12 - an undocumented factory connection variant, so ask for the datasheet to confirm the exact termination.
Three-wire PNP suits controllers whose inputs sink current; the switch then presents a firm high level with none of the contact bounce a reed element produces. The G profile letter fixes how the body seats in the cylinder's switch groove - it is a fit code only, so verify it against your cylinder before ordering.

|---|---|
| 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. |
| P | Output: PNP 3-wire. Blank is 2-wire, N is NPN 3-wire, P is PNP 3-wire. |
| 12 | 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 · PNP 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-PC12 Is Used
Robotic grippers
Signals open and closed positions of a gripper cylinder on an electronics assembly robot, wired PNP straight into the cell controller.
Weld cell clamps
Verifies clamp-cylinder closure in an automotive spot-welding cell before the robot is cleared to fire the gun.
High-cycle press feed
Counts piston arrivals on a press-feed cylinder where a reed contact would bounce and eventually wear out.
Is the Airtac DMSG Electronic Sensor DMSG-PC12 the Right Switch?
Choose this switch when the control circuit calls for a sourcing PNP input on 5-30 V DC and you want the fast, wear-free cycling only solid-state sensing gives. Because C12 is not a decoded option in our data, treat the termination as confirm-from-datasheet; the flying-lead and M8/M12 connector versions are fully documented if you prefer certainty. As with every model here, order the cylinder with its built-in magnet and check that the G profile seats in the groove.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (PNP 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 pnp 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-PC12 FAQ
Electronic solid-state sensing, PNP 3-wire output, 5-30 V DC supply, IP64 general-type enclosure. The C12 wiring code is a factory connection variant we confirm from the datasheet on request.
Only on a cylinder fitted with the piston magnet (the built-in -S option), and only if the G profile seats in that cylinder's sensor groove. A plain cylinder gives no signal, and forcing a mismatched profile into the groove will not seat properly.
