Airtac DMSG Electronic Sensor DMSG-050-W
The AirTAC Airtac DMSG Electronic Sensor DMSG-050-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 5 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-050-W
The DMSG-050-W pairs a 2-wire electronic switching element with a 5 m flying lead, a 10-28 V DC supply range and IP64 sealing. Clipped into the groove of an AirTAC cylinder that carries the magnet option, it reports piston position to your controller with no moving contact of its own.
Its W suffix is a factory variant code whose definition is not in our published data. We quote it at the general IP64 specification and will look up the exact meaning of W from the datasheet for you. As with every model in this range, the profile letter G has to match the groove of the cylinder it is pushed into.

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-050-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. |
| 050 | 5 m flying lead. 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 · 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-050-W Is Used
Machine rebuild spares
Specified where an OEM drawing names the W code on rebuilt filler frames, with the variant's exact meaning verified against the datasheet before installation.
Service-friendly retrofit
Long 5 m tails let maintenance reroute piston sensing on an upgraded pallet wrapper without cutting new conduit.
Controller position inputs
Feeds clamp-cylinder position signals on a robot cell guard circuit back to the controller over a single series-connected pair.
Is the Airtac DMSG Electronic Sensor DMSG-050-W the Right Switch?
Treat the electrical side as a standard DMS part: solid-state electronic output, DC supply only, and 2-wire series connection unless you move to an N or P model. Reed-based CMS alternatives take 5-240 V AC/DC and can be wired either way round, which matters on legacy AC panels. Choose a plain flying lead when cost and cut-to-length routing matter; choose M8/M12 when the sensor must unplug at a manifold. Because W is unlisted, we keep the rating at the general IP64 level rather than assuming washdown IP68. Confirm the G groove fit and the cylinder's magnet option before you commit.
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-050-W FAQ
Type: electronic (solid-state) position switch. Output: 2-wire. Supply: 10-28 V DC. Protection: IP64 (general type). Wiring: 5 m flying lead. The W code position is not documented in our data, so we quote the general specification and confirm the exact variant from the datasheet.
Yes - the 2-wire output wires in series with the load much like a mechanical contact and can drive a PLC DC input, but note that a small leakage current flows even in the off state. If the input card needs a cleaner switched signal, a 3-wire NPN or PNP DMS model is the better match; check the card type before ordering.
