Airtac DMSG Electronic Sensor DMSG-N100
The AirTAC Airtac DMSG Electronic Sensor DMSG-N100 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
The DMSG-N100 is a solid-state electronic position switch that reads the piston magnet of an AirTAC cylinder fitted with the magnet option. Output is NPN 3-wire, supplied from 5-30 V DC, with a 10 m flying lead for long cable runs back to the panel. General construction carries an IP64 rating.
Because the contact is electronic rather than mechanical, there is no contact bounce to worry about, which suits cylinders that index quickly and often. The G in the code sets the body shape that seats in the matching sensor groove of the cylinder - confirm the profile against your cylinder before ordering, and note the switch alone detects nothing without the magnet option.

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 Is Used
PLC input on a long run
NPN 3-wire signal over a 10 m lead reaches a remote control panel from a packaging machine cylinder without intermediate terminals.
High-cycle indexing
Solid-state switching with no mechanical contact suits an assembly station where a cylinder cycles hundreds of times per minute.
End-of-stroke proof
Confirms full extension of a clamping cylinder on a pressing line so the robot only advances when the part is secured.
Is the Airtac DMSG Electronic Sensor DMSG-N100 the Right Switch?
Pick this NPN version when your PLC input card sinks current - the 3-wire hook-up delivers a cleaner signal than a 2-wire switch wired in series. The 10 m flying lead covers distant cabinets without junction boxes; if you prefer plug-and-leave maintenance, an M8 or M12 connector variant lets crews unplug for service instead of cutting leads. The G profile must match the cylinder groove, and the cylinder itself needs the built-in magnet.
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 FAQ
It is an electronic (solid-state) switch with NPN 3-wire output, 5-30 V DC supply, IP64 protection and a 10 m flying lead. The G profile defines the mounting fit for the cylinder groove.
A 2-wire switch wires in series like a mechanical contact and carries a small leakage current; a 3-wire NPN switch gives the PLC input a cleaner, dedicated signal. Match NPN to a sinking input card - PNP versions exist for sourcing cards.
