Airtac DMSE Electronic Sensor DMSE-050-W
The AirTAC Airtac DMSE Electronic Sensor DMSE-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 DMSE Electronic Sensor DMSE-050-W
This DMSE-050-W is the standard E-profile 2-wire electronic switch with a trailing -W special code. The switch reads the piston magnet of an AirTAC cylinder carrying the built-in magnet option, runs on 10-28 V DC and uses a 5 m flying lead. Housing protection remains IP64. AirTAC has not published what -W denotes in the code we hold, so we treat it as a factory variant and will confirm the exact feature from the datasheet on request.
Electrically it still behaves as the familiar 2-wire solid-state unit: the signal path closes when the magnetised piston reaches the switch, and the circuit sees it much like a sealed contact. Do not assume -W carries the IP68 sealing of the -RW option - if washdown or oil mist is your concern, ask us about the RW version too. Match the E profile to your cylinder's groove before you buy.

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 | DMSE · 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 DMSE Electronic Sensor DMSE-050-W Is Used
Carriage end-stop on a transfer line
Mounted in the groove of a magnet-fitted transfer cylinder, the switch flags full carriage extension to the line PLC. The 5 m lead spans the distance to the local I/O box.
Tool-slide position interlock
A sliding tool holder on a special-purpose machine proves retracted position through this switch before the next cycle step is released, wired in series at 10-28 V DC.
Multi-station lift table sensing
Lift cylinders on a modular assembly station each carry a DMSE-050-W, giving the cell controller discrete up/down confirmation over short cable runs cut from the 5 m lead.
Is the Airtac DMSE Electronic Sensor DMSE-050-W the Right Switch?
Order this part number only when your build sheet literally specifies -W; otherwise the plain DMSE-050 is the documented general type. The electrical core is unchanged: 2-wire connection, 10-28 V DC, 5 m lead. For harsh wet or oily locations the -RW variant is the version with published IP68 waterproof, oil-resistant and flex-resistant sealing. As with every DMS switch, a magnet-equipped cylinder is required and the profile letter must agree with that cylinder's sensor 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 DMSE Electronic Sensor DMSE-050-W FAQ
The -W position of the ordering code is a factory variant that is not explained in the catalogue data we hold. We keep the protection rating at the general IP64 value and will confirm precisely what -W adds from the datasheet if you send us an enquiry.
Not on the strength of the -W code alone. For washdown, splashing coolant or oil mist, the documented choice is the -RW version of the DMS family, which lifts sealing to IP68 with waterproof, oil-resistant and flex-resistant construction. Tell us your environment and we will quote the right option.
