Airtac DMSHS Electronic Sensor DMSHS-030
The AirTAC Airtac DMSHS Electronic Sensor DMSHS-030 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 DMSHS Electronic Sensor DMSHS-030
The DMSHS-030 belongs to AirTAC's electronic DMS sensor line: a solid-state switch that trips when the magnet in a suitably equipped piston passes its seat. It presents a 2-wire output, accepts 10-28 V DC, seals to IP64, and terminates in a 3 m flying lead - the longest standard bare cable in the range, handy when the nearest terminal rail is a frame-width away. The S directly behind the profile letter H is a factory variant; quote your cylinder series and we will confirm what it denotes from the datasheet.
Three metres of bare cable can be routed through a duct and cut flush at the terminal, avoiding connector blocks altogether. As with every 2-wire electronic switch it behaves like a contact in series with the load, so retrofitting into an existing DC circuit is straightforward. The profile H is a fit code for the cylinder groove, not a grade - and without the factory magnet option the sensor has nothing to read.

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 · 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 DMSHS Electronic Sensor DMSHS-030 Is Used
Test rig traverse carriage
A traverse carriage on an R&D test rig reports its end positions through sensors wired by 3 m leads straight to a bench terminal strip.
Sorter divert arm feedback
On a parcel sorter, each divert arm's cylinder carries a sensor whose long lead reaches the central control rack without any splicing.
Long-run duct routing
Where the cylinder sits two frames away from the panel, the 3 m bare lead is ducted the whole way and trimmed at the terminal - no connector in the vibration path.
Is the Airtac DMSHS Electronic Sensor DMSHS-030 the Right Switch?
Pick this DMS unit when the circuit is DC, the run is long, and a connector would just be cut off anyway. A 3-wire NPN or PNP DMS is the upgrade path for PLC cards that want a dedicated signal; a CMS reed switch is the answer where AC is present or the 5-240 V AC/DC span is needed. Washdown and oil-mist zones belong to the -RW build with its IP68 sealing, not this general type. Above all, the profile letter has to match the groove of your magnet-fitted cylinder - send the series for confirmation.
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 DMSHS Electronic Sensor DMSHS-030 FAQ
Electronic (solid-state) switch type, 2-wire output, 10-28 V DC supply, IP64 general protection, 3 m flying lead. Current, voltage drop and timing figures are not published here - confirm from the datasheet.
No. Lead length is a wiring choice, not an electrical one - the 3 m cable simply reaches a distant terminal point and can be trimmed. What matters electrically is matching the 10-28 V DC supply and, if you step to a 3-wire DMS, choosing NPN or PNP to suit your PLC input.
