Airtac DMSH Electronic Sensor DMSH-050-W
The AirTAC Airtac DMSH Electronic Sensor DMSH-050-W 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-W
The DMSH-050-W is an AirTAC DMS electronic position switch, solid-state with a 2-wire output. It clips into the sensor groove of an AirTAC cylinder fitted with the built-in piston magnet and closes the circuit when the piston reaches it. Supply is 10-28 V DC, protection is IP64 as a general type, and wiring is a flying lead of 5 m. The trailing code W is a factory variant not defined in our catalogue data; send the datasheet request and we will confirm what it stands for.
Because the output is 2-wire, this switch sits in series with your load just like a mechanical contact, so integration is simple and there is no NPN or PNP polarity to check. The solid-state element has no moving parts, so it tolerates rapid cycling without the contact bounce a reed switch can show. The H profile letter defines how the body seats in the cylinder groove - match it to your cylinder series before ordering, and confirm the exact fit with us.

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-W Is Used
End-of-stroke check on a carton sealer
Mounted in the groove of a magnet-equipped AirTAC cylinder on a carton sealing head, the 5 m lead reaches the machine junction box without extensions, confirming the press stroke is complete before the taping cycle advances.
Slide table positioning in an assembly cell
A 2-wire series connection into the cell relay keeps wiring simple on a pneumatic slide table; the solid-state output handles frequent indexing between fixtures without contact wear.
Clamp verification on a fixture column
On a drilling fixture with clamping cylinders placed away from the control panel, the 5 m flying lead covers the distance and is trimmed to a tidy final length during install.
Is the Airtac DMSH Electronic Sensor DMSH-050-W the Right Switch?
Choose a 2-wire DMS when you want series wiring into a relay or PLC input without worrying about polarity. If your controller prefers a dedicated NPN or PNP signal, the 3-wire DMS variants are the alternative. A 5 m flying lead suits runs where an M8 or M12 connector is unnecessary; cut it to length on site. Note that -W on this model is an undocumented code position, distinct from the documented -RW waterproof IP68 version - confirm from the datasheet before assuming washdown suitability. The profile letter must match the sensor groove of your magnet-equipped AirTAC cylinder or the switch will not seat.
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-W FAQ
It is a DMS electronic (solid-state) position switch with a 2-wire output. Supply voltage is 10-28 V DC, protection is IP64 for the general type, and the wiring is a flying lead of 5 m. The W suffix is a factory variant we will confirm from the datasheet.
Yes. This switch reads the magnetic field of the piston, so the AirTAC cylinder must be ordered with the built-in magnet option. Without a magnet piston the switch never changes state. The H profile must also match the cylinder's sensor groove, so tell us the cylinder series and we will confirm the fit.
