Airtac DMSE Electronic Sensor DMSE-P020
The AirTAC Airtac DMSE Electronic Sensor DMSE-P020 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 pnp 3-wire output on 5-30 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-P020
This is the PNP version of AirTAC's DMS electronic switch family: the P code fixes a 3-wire sourcing output and 020 sets a 2 m flying lead that you dress to the machine's routing. The E-profile body sits in the cylinder's sensor groove and reads the piston magnet. Supply range is 5-30 V DC and the general housing holds an IP64 rating.
A PNP output sources current into the PLC input, the convention most European control platforms follow, so the signal lead feeds a positive logic level when the magnet arrives. Because the switching element is a transistor, there is no mechanical contact to bounce or wear out, which suits high-cycle automation. The E letter only defines the groove fit - send us the cylinder series and we will confirm the mechanical match.

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 · PNP 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-P020 Is Used
Press die clamps
Feeds a sourcing signal to a European-built press controller each time a die-clamp cylinder locks, blocking the stroke until all clamps confirm.
AS/RS lift tables
Reports the top and bottom positions of hoist cylinders on a storage-retrieval machine so the crane controller sequences lifts safely.
Torque-rig fixturing
On an assembly-line torque station, the switch proves the fixture cylinder has clamped the part before the nutrunner is enabled.
Is the Airtac DMSE Electronic Sensor DMSE-P020 the Right Switch?
Order the P version when the PLC input cards expect a sourcing signal, the standard on many European platforms; NPN machines take the N build instead. The 2 m flying lead suits direct termination on a terminal strip and gives free dress length in the panel; step up to an M8 or M12 connector build where switches must unplug during service. Protection is IP64 as standard, and the -RW option lifts that to IP68 for wet zones. Ordering also demands a piston with the factory magnet and a groove-matched E profile.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (PNP 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 pnp 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-P020 FAQ
Electronic (solid-state) type, PNP 3-wire sourcing output, 5-30 V DC supply, IP64 protection in the general build, terminated in a 2 m flying lead. It detects only the magnet of an AirTAC cylinder piston; load ratings are a datasheet matter, so confirm them with your RFQ.
Match the sensor to the input card: PNP sources current and is standard on many European controls, while NPN sinks and is common on Asian-platform machines. Both share the same DMS body and 5-30 V DC supply. Also check that the E profile fits your cylinder's groove, and treat a -W suffix as an undocumented special - we confirm it from the datasheet instead of assuming it matches -RW.
