Airtac DMSG Electronic Sensor DMSG-P020
The AirTAC Airtac DMSG Electronic Sensor DMSG-P020 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 with a 2 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-P020
The DMSG-P020 is an AirTAC DMS electronic position switch - solid-state, no moving contact - that reads the piston magnet of a suitably equipped AirTAC cylinder and reports end-of-stroke electrically. Its P code gives a PNP 3-wire output for DC PLC inputs, the supply range is 5-30 V DC, the general housing carries IP64, and connection is a 2 m flying lead.
Because a three-wire PNP output drives the input card directly instead of sitting in series with the load, the signal a PLC sees is cleaner than from a two-wire switch - the reason many machine builders reserve the P and N versions for controller inputs. Profile G is a groove-fit code, not a grade: match it to your cylinder body before ordering, and confirm the exact seating with us.

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-P020 Is Used
CNC fixture clamp confirm
Fitted at full stroke of a clamping cylinder, the PNP output feeds a dedicated PLC input so the controller releases the spindle only after the workpiece is verifiably clamped.
Pick-and-place retract signal
On a vacuum gantry, the switch marks the fully retracted position of the vertical cylinder, preventing arm traverse while the gripper is still down on the part.
Pop-up stopper position
A pneumatic stopper on a parcel sorter reports its up state over the 2 m lead, letting the divert gate fire in time for each package.
Is the Airtac DMSG Electronic Sensor DMSG-P020 the Right Switch?
Pick this model when your circuit is DC and the input card expects a sourcing PNP signal. If your PLC uses sinking NPN inputs, choose the DMSG-N variant instead; if you need polarity-free AC or DC operation, the CMS reed range covers 5-240 V AC/DC with a mechanical contact. The 2 m flying lead suits fixed, cut-to-length wiring; M8 or M12 connector codes are there for frequent unplug-and-service access. The profile letter must seat in your cylinder's sensor groove, and the cylinder itself must carry the built-in magnet option - a bare switch senses nothing.
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-P020 FAQ
It is a solid-state electronic switch with a PNP 3-wire output, a 5-30 V DC supply range, IP64 protection in the general build and a 2 m flying lead. It signals only when mounted on a magnet-equipped cylinder.
PNP sources voltage toward the input; the DMSG-N code sinks it instead. Match the letter to your PLC input card - sourcing inputs want PNP, sinking inputs want NPN. Both detect the same piston magnet.
