Airtac DMSE Electronic Sensor DMSE-N050-W
The AirTAC DMSE Electronic Sensor DMSE-N050-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 npn 3-wire output on 5-30 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-N050-W
The DMSE-N050-W is a solid-state electronic position switch from AirTAC's DMS range. It has no moving contact: a sensing element inside the body reads the magnet built into the piston of an AirTAC cylinder (the -S magnet option) and closes the circuit electronically when the piston arrives. This version is the NPN 3-wire type, so it sinks current into your controller input and is wired with a separate supply line, a ground line and one signal line. The N050 wiring is a 5 m flying lead cut to suit the route to your cabinet. Supply voltage is 5-30 V DC and the body carries IP64 protection.
Because it is three-wire NPN rather than a two-wire loop, the switch delivers a crisp, low-leakage signal to the PLC input card - useful where two-wire leakage current could be misread as a permanent ON. The trailing W in the code is a factory special variant; we will confirm its exact meaning from the AirTAC datasheet on request, and the general-type IP64 rating applies. Note that the E profile is a fit code for the cylinder's sensor groove, not a grade - it must match the groove of your cylinder series, so confirm the fit before ordering. A switch without a magnet-equipped cylinder detects nothing.

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 · NPN 3-wire · 5-30 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-N050-W Is Used
PLC end-of-stroke inputs
Wired to a sinking DC input card on an assembly machine, the NPN output gives the controller an unambiguous piston-position signal at each end of the stroke.
Clamp verification on fixtures
Fitted to magnet-equipped AirTAC clamp cylinders, the switch confirms the workpiece is fully clamped before the machining cycle is allowed to start.
Remote cabinet over long runs
The 5 m flying lead reaches a control panel mounted well away from the actuator, letting you route the cable through the machine spine and trim it to length on site.
Is the Airtac DMSE Electronic Sensor DMSE-N050-W the Right Switch?
Choose this DMSE-N050-W when your controller input card is a sinking (NPN) type and you want the cleanest possible signal - three-wire solid-state output beats a two-wire loop for leakage and signal quality on PLC inputs. The 5 m flying lead suits long or routed cable runs; if you need plug-and-leave service access, an M8 or M12 connector version can be swapped in minutes instead. Running a PNP input card? Pick the P variant of the same DMS switch instead - NPN and PNP are not interchangeable. Prefer AC supply or a mechanical contact? Move to the CMS reed family, which covers 5-240 V AC/DC. This unit stays IP64 as a general-type switch; only the -RW build raises DMS protection to IP68. Whatever you choose, the profile letter has to seat in your cylinder's groove and the cylinder must be the magnet-equipped version.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (NPN 3-wire)
- ✓ Supply rail is 5-30 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 5-30 V DC.
- check Wire npn 3-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-N050-W FAQ
It is an AirTAC DMS electronic (solid-state) position switch with NPN 3-wire output, supplied from 5-30 V DC and protected to IP64 as a general-type unit. The connection is a 5 m flying lead. The W suffix is a special code we confirm from the datasheet on request.
A 3-wire NPN output carries no load current except when signalling, so leakage stays low and the PLC input sees a clean edge - ideal for fast or closely spaced detection points. Two-wire switches sit in series like a mechanical contact and leak slightly in the off state. Just make sure your input card matches NPN (sinking); otherwise order the PNP variant. And remember the target cylinder needs the built-in magnet option.
