The AirTAC Airtac DMS Electronic Cylinder Switches DMSE-PM08 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 m8 connector. It only works on a cylinder that carries a piston magnet.
AirTAC's DMSE-PM08 is a DMS-series electronic position switch with a PNP 3-wire solid-state output. It clips into the sensor groove of an AirTAC cylinder that carries the built-in piston magnet and signals end-of-stroke or mid-stroke position to your controls. This version ends in an M8 connector with a 0.5 m pigtail, so the sensor can be unplugged during service instead of cutting a flying lead. Supply is 5-30 V DC and the general-type body is rated IP64.
The M8 plug is the real advantage here: on machines where sensors are swapped or cables damaged, a connector swap takes seconds and needs no re-termination at the PLC side if you use a matching M8 cordset. Profile E is the fit code for the cylinder groove - check it against your cylinder series. A switch alone detects nothing; the piston magnet option is required.

2-wire versions run 10-28 V DC; NPN / PNP 3-wire versions run 5-30 V DC. IP64 as standard. Order the RW version where coolant, washdown or constant cable flexing is present. Switching distance, response time, current rating, voltage drop, LED behaviour, contact life, weight and dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

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.
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.

| Mounting parts | F-MQ (round body), F-ACT (tie-rod) |
The solid-state PNP output has no contacts to bounce, so the PLC receives a stable clamp-closed signal even at rapid cycling rates on rotary indexing tables.
With an M8 connector, technicians unplug and replace a damaged switch in seconds - no wire stripping, no terminal block rewiring, minimal line stoppage.
The 0.5 m pigtail keeps cabling short inside a compact machine base, with the M8 junction handled at the nearest distribution point.
Go with this model when you want a PNP sourcing signal for a PLC input plus the serviceability of an M8 connector on a short 0.5 m pigtail - ideal where the switch sits near a junction box. If your input card is sinking, order the NPN variant (code N). Flying-lead versions (2/3/5/10 m) cost less but must be cut and re-terminated; the connector pays off when cables get changed often. Confirm that profile E matches your cylinder's groove, and that the cylinder has the magnet option.
Quick checklist
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.
Family DMS, so it is an electronic solid-state switch. Output is PNP 3-wire, supply voltage 5-30 V DC, protection IP64 (general type), wiring an M8 connector with a 0.5 m lead. Profile E must seat in your cylinder's sensor groove - confirm the fit against your cylinder series.
Yes - that is what the M8 connector is for. Pair it with a mating M8 cordset of the length your installation needs, keeping the total wiring within the limits your PLC input card tolerates. The connector also lets you disconnect the sensor for service without cutting any wires.
