The AirTAC Airtac DMS Electronic Cylinder Switches DMSG-PM12 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 m12 connector. It only works on a cylinder that carries a piston magnet.
This DMSG-PM12 is a solid-state AirTAC position switch with a 3-wire PNP output, made to read the piston magnet of a magnet-option AirTAC cylinder. It terminates in an M12 connector with a 0.5 m lead, ready for a standard M12 cordset. Operating voltage is 5-30 V DC and the general-type housing is IP64.
M12 is the larger industrial connector standard, mechanically tougher than M8 where cabling gets knocked on the machine frame. Being electronic, the output switches without the mechanical wear or bounce of a reed element, suiting repetitive machine cycles. Treat the G profile as a groove-fit code and confirm it against the cylinder you are fitting - we can check the exact match from the datasheet.

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.

Stroke confirmation on clamp cylinders across an automotive sub-assembly line, plugged straight into the line's existing M12 cabling.
Confirms part-ejector cylinder retraction in a stamping press before the next stroke is permitted.
Position feedback on a wafer-carrier slide cylinder in a cleanroom tool, where contactless solid-state switching avoids a wearing mechanical contact.
Specify this model when the PLC input is a sourcing (PNP) type on 5-30 V DC and the machine already runs M12 cordsets. Choose a flying-lead version instead if nothing will ever be unplugged, and the -RW build if washdown or cable tracks demand IP68. Before ordering, make sure the cylinder carries the piston magnet option and that the G profile seats in 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 type, PNP 3-wire output, 5-30 V DC supply, IP64 enclosure as standard, ending in an M12 connector fitted with a 0.5 m lead. The G profile must match your cylinder's groove; we confirm exact fit from the datasheet.
This model is M12; M8 suits tighter cordset routing. Neither runs on AC: DMS electronic switches are DC only, so if your circuit is 24 V AC or line voltage you need a CMS reed switch instead, which accepts 5-240 V AC/DC. A magnet-equipped cylinder is required either way.
