Airtac DMSGS Electronic Sensor DMSGS-030
The AirTAC Airtac DMSGS Electronic Sensor DMSGS-030 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 with a 3 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSGS Electronic Sensor DMSGS-030
The DMSGS-030 is an AirTAC DMS electronic position switch, decoded as profile G with a 3 m flying lead. Like every DMS sensor it is solid-state rather than a reed contact, and it reports piston position by reading the magnet that is built into an AirTAC cylinder when the magnet option is ordered. The output is 2-wire on 10-28 V DC, with IP64 protection in the general type.
Electronic sensing means no contact bounce and a long service life under frequent stroking - a natural fit for palletizing or pick-and-place heads that actuate thousands of times per shift. The G letter is a groove-fit code, not a grade; the S that follows it is a factory variant we will confirm from the datasheet, and no cylinder-series mapping is implied.

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 DMSGS Electronic Sensor DMSGS-030 Is Used
Palletizer gripper check
Verifies full close of the gripper cylinder on a bag palletizer before the arm lifts; the 3 m lead spans from the gripper to the local junction box.
Pick-and-place Z-stroke signal
Tells the robot controller the vertical cylinder has reached the down position, with no contact bounce to false-trigger the cycle.
Press gate lock indication
Confirms the gate cylinder on a small pneumatic press line is fully locked before an operator can start a stroke.
Is the Airtac DMSGS Electronic Sensor DMSGS-030 the Right Switch?
A 2-wire solid-state switch joins your circuit in series, the way a mechanical contact would, and keeps panel wiring minimal. If the PLC input card demands NPN or PNP polarity, choose a 3-wire DMS in the same family. Three metres of lead covers machines where the sensor sits mid-frame and the cabinet is some distance away; beyond that, look at 5 m, 10 m, or an M8/M12 connector for easy later swaps. Check the G profile against your cylinder groove before ordering, and remember the cylinder itself needs the magnet option.
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 DMSGS Electronic Sensor DMSGS-030 FAQ
The DMSGS-030 is electronic (solid-state), output 2-wire, supply 10-28 V DC, IP64 as the general type, wired with a 3 m flying lead. Figures such as switching current and voltage drop are not published here - confirm from the datasheet.
The 2-wire version connects in series like a mechanical switch and carries a small leakage current. A 3-wire DMS (NPN or PNP) hands the PLC input a cleaner dedicated signal. Choose by what your input card expects.
