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

About the Airtac DMSG Electronic Sensor DMSG-030-W
The DMSG-030-W is the general AirTAC electronic position switch in profile G, built with a 3 m flying lead and a 2-wire solid-state output rated 10-28 V DC at IP64. Like every switch in this class it senses nothing on its own - the piston of the target cylinder must be fitted with the factory magnet option.
The trailing W sits in an undocumented code position: AirTAC lists it in the catalogue, but its meaning is not published, so we treat the unit as the standard IP64 general type and will read exactly what W adds from the datasheet on request. Bear in mind too that G defines only the groove fit, which has to line up with your cylinder body.

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-030-W Is Used
Relay panel retrofit
Drops into a machine rebuild where the 2-wire output replaces a worn mechanical limit switch without rewiring the existing relay panel.
Gate cylinder on a press line
Signals that the safety-gate cylinder on a stamping press has fully withdrawn before the die area is released to the operator.
Fixed cabinet distance
The 3 m tail spans the distance to a control cabinet mounted beside the machine, keeping a bottling line's sensor wiring free of splice points.
Is the Airtac DMSG Electronic Sensor DMSG-030-W the Right Switch?
Order this code only if your drawing or the machine it replaces calls out the W variant; otherwise the standard DMSG-030 performs the same 2-wire, 10-28 V DC job. Electronic DMS and EMS switches are DC-only solid-state parts, whereas a CMS reed switch tolerates 5-240 V AC or DC and has no polarity to observe. Flying-lead wiring is the economical route and can be trimmed to length on site; choose an M8/M12 connector version if maintenance staff unplug sensors regularly. This is the general type, not the -RW IP68 build, and its G profile has to seat in the sensor groove of a magnet-fitted cylinder.
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-030-W FAQ
The core set is: electronic solid-state type, 2-wire output, 10-28 V DC supply, IP64 protection and a 3 m flying lead. We hold it at the general rating because the W suffix is undocumented; anything W adds beyond that will be read from the datasheet on request.
We do not know, and we will not guess: -RW is the documented waterproof, oil-resistant, flex-resistant build with IP68, while W on its own is a factory variant code not defined in our data. If washdown sealing is what you need, specify the -RW version instead; otherwise ask us to verify W before ordering.
