Airtac DMSH Electronic Sensor DMSH-N100
The AirTAC Airtac DMSH Electronic Sensor DMSH-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 DMSH Electronic Sensor DMSH-N100
The DMSH-N100 is a solid-state electronic position switch from AirTAC's DMS family. The N in the code sets an NPN 3-wire output that sinks current into a PLC input, the H profile body clips into the matching sensor groove of an AirTAC cylinder, and 100 decodes to a 10 m flying lead. It runs on 5-30 V DC and the general-type housing is rated IP64.
A three-wire NPN switch carries its own supply reference, so the signal reaching the controller is cleaner than a two-wire unit wired in series with the load - a real advantage on a 10 m cable span like this one. Remember the switch reads nothing by itself: it must sit in the groove of a magnet-equipped AirTAC cylinder (the -S option), and the H profile has to match that cylinder's groove, so confirm the exact fit with us before ordering.

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 | DMSH · 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 DMSH Electronic Sensor DMSH-N100 Is Used
Long conveyor run end-of-stroke
On a distribution-centre belt with the control panel far from the stopper cylinder, the 10 m flying lead reaches the PLC cabinet without a junction box, and the NPN output drives a sourcing input card cleanly.
CNC fixture clamp confirmation
A clamping cylinder with the magnet option reports 'part gripped' to the machine controller; the solid-state contact tolerates the rapid clamp-unclamp cycles of a machining centre without contact bounce.
PLC I/O panel position feedback
Where an input module needs a defined sinking signal rather than a series-wired contact, the 3-wire NPN output gives the controller a crisp transition at each end of piston travel.
Is the Airtac DMSH Electronic Sensor DMSH-N100 the Right Switch?
Choose NPN (this model) when your PLC input card sources current, or pick the P variant if the card sinks. A flying lead keeps cost down and can be trimmed on site; if you would rather unplug the switch for service, step up to an M8 or M12 connector version. Washdown or cable-track duty calls for the -RW variant, which lifts protection to IP68. Whatever you pick, the profile letter is a groove-fit code - match it to your cylinder series, which we can confirm from the datasheet.
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 DMSH Electronic Sensor DMSH-N100 FAQ
It is a DMS electronic (solid-state) switch with an NPN 3-wire output. Supply voltage is 5-30 V DC, protection is IP64 for the general type, and the wiring is a 10 m flying lead. Switching current and other figures: confirm from the datasheet.
NPN sinks current to the PLC input; choose PNP if your input card is the sinking type. And yes - the switch detects the piston magnet only, so the cylinder must be ordered with the built-in magnet option and the H profile must seat correctly in its groove.
