Airtac DMSG Electronic Sensor DMSG-C12
The AirTAC Airtac DMSG Electronic Sensor DMSG-C12 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 DMSG Electronic Sensor DMSG-C12
DMSG-C12 decodes to an electronic, solid-state position switch with 2-wire output, a 10-28 V DC supply and an IP64 housing, in the G profile that must seat in the matching cylinder's sensor groove. The trailing C12 is a connection code whose hardware form and length are not covered by our catalogue data, so we read it off the datasheet for you on request.
Solid-state switching means the contact never mechanically opens or closes: there is no bounce, so a PLC or relay input sees one clean transition per pass of the piston magnet. Confirm the cylinder is the magnet-equipped version, otherwise the switch has nothing to detect.

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 · 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 DMSG Electronic Sensor DMSG-C12 Is Used
Rotary indexing table
Detects clamp-cylinder lock on each station of a rotary indexing table, where frequent cycling suits a bounce-free solid-state output.
Lab test rig
Position confirmation for the actuator on a materials test rig, logged by a data acquisition input.
Sorting module
Verifies ejector-cylinder extend on a parcel sorting module wired back to the sortation PLC.
Is the Airtac DMSG Electronic Sensor DMSG-C12 the Right Switch?
This code suits a 2-wire, 10-28 V DC installation where you want solid-state reliability and will confirm the C12 connection detail from the datasheet. Series wiring keeps the cabinet work simple; a 3-wire NPN or PNP model is the choice when the input card demands a dedicated polarity-correct signal. For splashing oil, washdown zones or a flexing cable run, move to the -RW version with its IP68 rating. As with every sensor here, the G profile is a fit code, not a grade, and the piston magnet is mandatory.
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 DMSG Electronic Sensor DMSG-C12 FAQ
Electronic (solid-state) type, 2-wire output, powered from 10-28 V DC, protected to IP64, with connection code C12 - a variant we confirm from the datasheet. The G profile letter fixes the cylinder-groove fit.
The CMS reed switch closes a mechanical contact, accepts 5-240 V AC or DC and has no polarity, but the contact has a finite life and can bounce. This DMS electronic model is DC-only at 10-28 V, produces no bounce, and cycles faster - the trade-off is matching supply polarity and voltage.
