Airtac DMSG Electronic Sensor DMSG-100-W
The AirTAC Airtac DMSG Electronic Sensor DMSG-100-W 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 10 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-100-W
The DMSG-100-W is an electronic, solid-state magnetic switch with a 2-wire output, built in the G profile whose shape seats it in the cylinder's sensor groove. Supply range is 10-28 V DC and the general-purpose housing is rated IP64. The wiring code gives you a 10 m flying lead, long enough to reach a control panel without splicing.
The trailing -W is a factory special variant that our catalogue data does not decode, so we confirm its exact meaning from the AirTAC datasheet on request; the stated IP64 protection applies as for the general type. Like every switch in this class it senses nothing by itself - the cylinder must be ordered with the built-in piston magnet.

2-wire versions run 10-28 V DC; NPN / PNP 3-wire versions run 5-30 V DC. IP64 as standard. Order the RW version where coolant, washdown or constant cable flexing is present. Switching distance, response time, current rating, voltage drop, LED behaviour, contact life, weight and dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: Airtac DMSG Electronic Sensor DMSG-100-W
| 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. |
| (blank) | Output: 2-wire. Blank is 2-wire, N is NPN 3-wire, P is PNP 3-wire. |
| 100 | 10 m flying lead. 020 / 030 / 050 / 100 are 2 / 3 / 5 / 10 m flying leads; M08 and M12 are M8 / M12 connector versions. |
| W | W - factory special code, confirm from datasheet. |
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-100-W Is Used
Timber mill hoist
Retract confirmation for the clamp cylinder of a log hoist, with the 10 m lead run back to the saw house panel.
Tray sealing machine
Verifies lid-press cylinder bottom position on a food tray sealer in a dry processing zone.
Dock leveller
Confirms full raise of a dock leveller ram, cabling from the pit back to the loading-bay control box.
Is the Airtac DMSG Electronic Sensor DMSG-100-W the Right Switch?
Order this code when you need the longest standard lead, 10 m, with solid-state switching on 10-28 V DC and the simplest series wiring. Do not assume -W adds washdown protection: only the -RW build is documented at IP68, so if water, oil or a moving cable track is involved, ask us to verify the -W scope or specify DMSG-100-RW instead. A 3-wire NPN or PNP version suits PLC inputs that want a clean dedicated signal. Whatever you pick, the G profile has to match your cylinder's groove - send the cylinder series and we will confirm the fit.
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-100-W FAQ
Electronic (solid-state) switch, 2-wire output, 10-28 V DC supply, IP64 protection, 10 m flying lead, G profile for the cylinder sensor groove, plus a -W special suffix. We confirm what -W stands for from the datasheet on request; no IP68 claim is made for it.
-RW is the documented waterproof, oil-resistant and flex-resistant build with IP68 protection. The scope of -W is not in our data, so for washdown or cable-track duty we recommend -RW unless the datasheet review shows otherwise.
