The AirTAC Airtac DMS Electronic Cylinder Switches DMSG-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.
The DMSG-PM08 is an AirTAC electronic magnetic position switch, PNP 3-wire, that detects the piston magnet inside a suitably equipped AirTAC cylinder. Its M8 connector comes fitted with a 0.5 m pigtail, so you plug in a matching M8 cordset of whatever length the machine needs. Supply is 5-30 V DC; the standard build is rated IP64.
The connector is the maintenance win: a technician can unplug the sensor at the machine for replacement without opening a junction box, while the cordset side is bought cut-to-length. Solid-state switching means no reed-style contact bounce during rapid cylinder cycling. The G profile is purely a groove-fit letter - confirm it seats in your cylinder before purchase.

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.

End-of-stroke signalling on gantry pick-and-place cylinders; the M8 plug lets a maintenance crew swap a failed sensor without rewiring.
Confirms ejector-cylinder return inside an injection mould set before the tool closes for the next shot.
Reports gripper-cylinder closure on a palletiser so the PLC times the layer push without a mechanical limit switch.
If your input card wants a sourcing PNP signal and you value tool-free sensor swaps, this M8 version fits: the 0.5 m pigtail reaches a nearby cordset entry. Fixed installations that never get serviced may be cheaper on a flying-lead build instead. For washdown areas or moving cable tracks, step up to the -RW variant, which lifts protection to IP68. Two prerequisites remain: a magnet-option cylinder, and a G profile that matches its groove.
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.
Electronic (solid-state) switch, PNP 3-wire output, 5-30 V DC supply, IP64 protection in the general type, terminating in an M8 connector with a 0.5 m lead. Pair it with a matching M8 cordset and confirm the G profile fits your cylinder groove.
A connector lets you unplug the switch for service or replacement and swap cordsets without rewiring - useful on tools and fixtures that are opened often. A flying lead is cheaper but hard-wired. Either way, a cylinder with the built-in magnet option is required, otherwise the switch never triggers.
