Airtac DMSE Electronic Sensor DMSE-050
The AirTAC Airtac DMSE Electronic Sensor DMSE-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 DMSE Electronic Sensor DMSE-050
The DMSE-050 is an AirTAC electronic position switch from the DMS range, built as a 2-wire solid-state unit with a 5 m flying lead. It senses the piston magnet inside an AirTAC cylinder fitted with the magnet option and closes the circuit when the piston passes the switch. Supply is 10-28 V DC and the general housing carries IP64 protection. Its E profile is a fit code, not a performance grade, so the letter only indicates the groove style it seats into.
Because the 2-wire design drops into the load path the way a mechanical contact would, you can treat it as a drop-in replacement for a dry-contact sensor with no polarity worry. The 5 m lead is generous enough to reach a cabinet or junction box on mid-size machines without an extension splice. Confirm the exact cylinder match for the E profile against your cylinder series before ordering.

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 |

Where the Airtac DMSE Electronic Sensor DMSE-050 Is Used
Clamp confirmation on a CNC fixture
Bolted into the groove of a magnet-fitted AirTAC clamping cylinder, the switch confirms the workpiece is clamped before the machining cycle starts. The 5 m lead reaches the machine control panel cleanly.
Gate position on a palletiser
A safety interlock gate driven by a magnet-equipped cylinder signals closed position via the DMSE-050. Wiring it in series with the guard circuit keeps the loop simple and low-voltage at 10-28 V DC.
Slot-in ejector feedback
On a packaging line eject station, the solid-state output signals end-of-stroke for each eject cylinder. No contact bounce means clean counting into the line controller.
Is the Airtac DMSE Electronic Sensor DMSE-050 the Right Switch?
Choose this 2-wire DMSE-050 when your circuit simply needs an on/off signal in series with a load - it behaves like a mechanical switch with no moving parts. If your PLC input card demands a dedicated NPN or PNP three-wire signal, step up to a DMSG-N or DMSG-P variant instead. The 5 m flying lead suits fixed installs where cutting the cable to length beats paying for a connector. Remember the switch is inert without a magnet-equipped cylinder, and the E profile must correspond to the sensor groove on that cylinder.
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 FAQ
It is a DMS electronic (solid-state) position switch with a 2-wire output, supplied at 10-28 V DC, protected to IP64 in the general version, and fitted with a 5 m flying lead. The E profile denotes the mounting fit for the cylinder groove.
A 2-wire switch sits in series with your load just like a mechanical contact, which keeps wiring minimal but leaves a small leakage current. A 3-wire DMS with an NPN or PNP output delivers a cleaner discrete signal straight into a PLC input, provided the output polarity matches the input card.
