The AirTAC Airtac DMS Electronic Cylinder Switches DMSG-M08 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 m8 connector. It only works on a cylinder that carries a piston magnet.
The DMSG-M08 is a solid-state electronic position switch from AirTAC's DMS range. It clamps into the sensor groove of a magnet-equipped AirTAC cylinder and signals each time the piston passes. Output is 2-wire, wiring is an M8 connector with a 0.5 m pigtail, supply is 10-28 V DC, and the general housing carries an IP64 rating.
Because it ends in a mating M8 plug rather than a bare lead, maintenance crews can detach the sensor for cylinder service and swap a damaged cord without rewiring terminals. Note that profile G is a fit code for the cylinder groove, not a performance grade - check it against your cylinder series before ordering.

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.

On a robotic pick-and-place cell, the M8 connector lets technicians detach the switch when the gripper is rebuilt between product changes.
Confirms gate-open positions on a bottling conveyor's pneumatic stop gates, plugging straight into M8 cordsets that run to the local I/O box.
Reports clamp-closed on a stamping press die clamp so the control will not cycle the press until the magnet has reached the switch.
Choose the electronic DMS family when your circuit is DC and you want bounce-free, fast cycling; a reed CMS switch suits wide 5-240 V AC/DC circuits instead. The 2-wire output wires in series like a mechanical contact, which keeps panel hookup simple. This M8 version wins where sensors are unplugged during changeovers - take a flying lead if you prefer cutting to length on site. The G profile must match your cylinder's groove, and the cylinder itself needs the built-in 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.
It is a solid-state electronic switch with a 2-wire output. Supply voltage is 10-28 V DC, protection is IP64 (general type), and the wiring is an M8 connector with a 0.5 m pigtail. The G profile must match the sensor groove of your cylinder.
A connector lets you detach the switch for cylinder maintenance and replace a damaged cord without opening the panel. A 2-wire electronic unit like this still wires in series like a mechanical contact, so hookup stays simple. The cylinder must have the built-in magnet option for any signal to appear.
