Airtac DMSH Electronic Sensor DMSH-PC12
The AirTAC Airtac DMSH Electronic Sensor DMSH-PC12 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. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-PC12
The DMSH-PC12 from AirTAC is a solid-state position sensor with a PNP 3-wire output for magnet-fitted cylinders. It operates from 5-30 V DC and carries IP64 in its general form. C12 is a connection code position that our data leaves undefined; treat it as a factory variant and we will verify the C12 interface from the datasheet on request.
Three-wire PNP gives the PLC a driven, bounce-free signal rather than the small leakage drop a 2-wire switch imposes in series with the load. The H profile again is purely a seating code for the cylinder groove - the catalogue does not map it to specific series, so check the fit with us first.

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-PC12 Is Used
High-cycle pick-and-place
A pick-and-place gantry uses the signal for the Z-axis down position, and the solid-state output handles rapid repetitive cycling without contact bounce.
Web-tension idler arm
On a converting line, it flags when the tension-arm cylinder reaches its correction limit so the drive can re-trim.
Serviceable machine retrofits
With a C12 connection code, this unit suits installations being converted to a pluggable wiring scheme; we confirm the C12 interface from the datasheet for you.
Is the Airtac DMSH Electronic Sensor DMSH-PC12 the Right Switch?
Settle on this switch when a sourcing PLC input is in play and the C12 connection suits your panel's wiring standard, pending datasheet confirmation from us. Against a 2-wire layout, the 3-wire PNP output keeps the input signal cleaner and unaffected by load leakage. Wet or oily locations call for the -RW IP68 variant of the DMS range; hot zones on other machines point to the CMS-H high-temperature reed switch. Do not forget the magnet-option cylinder and the groove-matched H profile.
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-PC12 FAQ
Electronic solid-state type, PNP 3-wire output, 5-30 V DC supply, IP64 protection in the general version, and a C12 connection code that is not documented in our data - we will verify what C12 specifies from the datasheet on request.
Yes. It only detects a piston that carries a magnet, so the cylinder must be ordered with the built-in magnet option, and the H profile must seat correctly in that cylinder's groove. Send us the cylinder series and we will check the fit.
