Airtac DMSH Electronic Sensor DMSH-050
The AirTAC Airtac DMSH Electronic Sensor DMSH-050 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 5 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-050
DMSH-050 is a solid-state electronic position switch from AirTAC's DMS range, set up as a 2-wire device that connects in series with your load and takes its 10-28 V DC across those same two conductors. The 5 m flying lead is the longest standard lead in the family, useful when the control panel is a good distance from the machine. IP64 is the enclosure rating. It signals when the piston of a magnet-equipped AirTAC cylinder passes its mounting point.
Because the 5 m run is already long, this version often saves a splice or junction box on larger frames. Check that profile H corresponds to the sensor groove of your cylinder - the letter is a mechanical fit code, not a performance grade, and the exact cylinder series it suits should be confirmed against your model before you buy.

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 DMSH Electronic Sensor DMSH-050 Is Used
High-bay lift position
On a vertical lift unit in a distribution warehouse, the 5 m lead drops from the cylinder down the mast to the drive panel without any joint.
Bottling filler cam timing
A rotary bottling filler uses the switch to verify filler-valve cylinders are home between cycles, the long lead reaching the control cabinet at the frame base.
Wafer transfer module
Inside a semiconductor wafer handling module, the contactless solid-state output confirms each transfer stroke cleanly, with the 5 m cable routed to the clean-side controller.
Is the Airtac DMSH Electronic Sensor DMSH-050 the Right Switch?
Take this 5 m version when distance, not signal conditioning, is the problem: the two-wire loop stays simple at 10-28 V DC and IP64. If the run grows beyond that, switch to an M8 or M12 connector type and use a longer pre-made cable; if a PLC needs NPN or PNP logic, choose the 3-wire DMS output instead. It must be paired with a cylinder carrying the built-in magnet, and profile H has to seat in that cylinder's groove.
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 DMSH Electronic Sensor DMSH-050 FAQ
It is an electronic (solid-state) switch, 2-wire output, 10-28 V DC supply, IP64 protection, supplied with a 5 m flying lead. It only produces a signal on an AirTAC cylinder that has the built-in piston magnet.
A flying lead is the simpler, cut-to-length option for one fixed installation. An M8 or M12 connector version is worth it when the switch may need unplugging for service or cable replacement. Profile H must fit the cylinder groove in both cases.
