Airtac DMSG Electronic Sensor DMSG-N100-W
The AirTAC Airtac DMSG Electronic Sensor DMSG-N100-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 npn 3-wire output on 5-30 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-N100-W
This DMSG-N100-W is the solid-state electronic switch with the factory W variant code on the end. It still reads the piston magnet of a magnet-equipped AirTAC cylinder, still gives NPN 3-wire output on 5-30 V DC, and still carries the 10 m flying lead. As the W suffix is not defined in the standard catalogue, treat the rating as the general IP64 type.
The W position of the code is a factory variant we will confirm from the datasheet on request - do not assume it matches another suffix such as RW. The G profile remains a fit code for the cylinder's sensor groove, so check it against your cylinder and remember the piston needs the magnet option for detection to happen at all.

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-N100-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. |
| N | Output: NPN 3-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 · NPN 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-N100-W Is Used
OEM machine retrofit
Drop-in replacement where an equipment manual specifies DMSG-N100-W on a machine-tool fixture cylinder.
Leveler and dock controls
NPN 3-wire confirmation of a dock leveler cylinder's parked position, signalled over the long 10 m lead to the door controller.
Multi-position jig sensing
Bank of switches along a clamping jig reports each cylinder's state individually to the PLC via separate 3-wire NPN channels.
Is the Airtac DMSG Electronic Sensor DMSG-N100-W the Right Switch?
Order this code when your drawing or a previous shipment names the -W suffix exactly; otherwise the plain DMSG-N100 is the equivalent published part. Both are NPN 3-wire, 5-30 V DC, with a cut-to-length 10 m lead that suits panels mounted far from the machine bed. If washdown or oil mist is your real concern, ask us about the documented -RW IP68 version instead of relying on the W code.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (NPN 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 npn 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-N100-W FAQ
The W is a factory special code not defined in the published catalogue. We will confirm its exact meaning from the datasheet on request. Electrically the switch is NPN 3-wire, 5-30 V DC, IP64, with a 10 m flying lead.
This is solid-state: DC supply only, no mechanical contact, no bounce, better for fast cycling. A reed switch has a mechanical contact, no polarity, and runs on AC or DC - choose by your circuit voltage and cycle rate.
