Airtac DMSH Electronic Sensor DMSH-P100
The AirTAC Airtac DMSH Electronic Sensor DMSH-P100 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 pnp 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-P100
DMSH-P100 is a solid-state DMS sensor from AirTAC that reads the piston magnet inside a magnet-option cylinder. The P stands for a PNP 3-wire output and 100 for a 10 m flying lead - the longest lead in the range, chosen when the control cabinet is far from the machine. It runs on 5-30 V DC and, as a general-type unit, is rated IP64.
A 10 m lead is a routing specification, not a shortcut: it lets you run wiring away from hot zones and moving parts without splices or extension joints. The profile letter H dictates which cylinder groove the body seats in, so match it to your series and confirm the exact fit with us.

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 · PNP 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-P100 Is Used
Divert gate on a sorting conveyor
A distribution centre's diverter arm needs a stroke-confirmation signal back to the WMS-linked PLC before the next parcel is released.
Stamping press feed
In a press shop, it reports that the sheet-feed cylinder has completed advance so the press can cycle safely.
Palletizer pusher
A palletizer's layer-push cylinder uses the sensor to confirm full extension, squaring each layer before the next is stacked.
Is the Airtac DMSH Electronic Sensor DMSH-P100 the Right Switch?
Choose DMS electronic types like this one when your circuit is DC and the input card expects PNP (sourcing) signals; a CMS reed switch suits AC or mixed-voltage panels instead, though its mechanical contact has a finite life. Compared with a 2-wire switch in series with the load, a 3-wire PNP output feeds the PLC input directly for a crisper signal. Ten metres of flying lead suits distant cabinets; an M8 or M12 connector version is better where sensors are swapped often. Fit requires the correct groove profile and a cylinder with the built-in magnet.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (PNP 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 pnp 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-P100 FAQ
Type: electronic (solid-state). Output: PNP 3-wire. Supply: 5-30 V DC. Wiring: 10 m flying lead. Protection: IP64 general type. All values come from the AirTAC catalogue; sensing distance and response time are not published there, so confirm any extra figures from the datasheet.
A long flying lead is cut to length and routed around hot zones or moving cable tracks without adding joints. If you need to unplug the sensor for fast service swaps, an M8 or M12 connector version is the better choice.
