Airtac DMSE Electronic Sensor DMSE-020-W
The AirTAC Airtac DMSE Electronic Sensor DMSE-020-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 2 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSE Electronic Sensor DMSE-020-W
This DMSE-020-W keeps the standard DMS electronic format: a solid-state sensing head, a 2-wire output, a 2 m flying lead and a 10-28 V DC supply in an IP64 body. It mounts in the sensor groove of a magnet-equipped AirTAC cylinder and reports piston position to your control circuit.
The trailing W is a factory variant code whose meaning is not spelled out in our catalogue data; we will confirm exactly what it changes from the datasheet on request, and we keep the published IP64 rating for this model. Profile E decides which cylinder groove the clip suits, so match it to your cylinder series before ordering.

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-020-W Is Used
Rotary indexing table
Fitted to the clamp cylinders of an indexing dial, the switch confirms each station is locked before the table indexes, with the 2 m lead dressed along the machine frame.
Carton erecting machine
On the flap-fold cylinders of a case erector, the 2-wire output drops straight into the existing series circuit without adding PLC input channels.
Clamping fixture on a jig
Welded jigs use groove-mounted switches to prove clamps are closed; the solid-state output avoids the contact bounce that plagues reed switches on fast reject cycles.
Is the Airtac DMSE Electronic Sensor DMSE-020-W the Right Switch?
Specify the DMSE-020-W where your machine calls for this exact factory variant of the 2-wire DMS switch. If you only need the general type, the plain DMSE-020 shares the same 10-28 V DC supply and 2 m lead. For harsh washdown zones or moving cable tracks, the documented -RW version lifts protection to IP68 - ask us before assuming the W does the same. The E profile must match the cylinder's groove, and the cylinder itself must carry the built-in magnet for any signal to appear.
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-020-W FAQ
Electronic (solid-state) switch, 2-wire output, 10-28 V DC supply, IP64 protection, 2 m flying lead, profile E for the cylinder groove fit. The -W suffix is a factory variant we will confirm from the datasheet. Current and timing figures: confirm from the datasheet.
We do not assume so. The documented -RW option adds waterproof, oil-resistant and flex-resistant construction for IP68; the meaning of -W alone is not in our data, so we quote it at IP64 and will verify the variant from the datasheet before you order.
