The AirTAC Airtac DMSGS Electronic Sensor DMSGS-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 2-wire output on 10-28 V DC. It only works on a cylinder that carries a piston magnet.
The DMSGS-P020 is AirTAC's PNP 3-wire electronic switch for cylinder position feedback. It senses the magnet built into the piston of a suitable AirTAC cylinder and sources a positive signal to the controller. Power comes from a 5-30 V DC supply, the 020 wiring is a 2 m flying lead you can cut to length, and the general-type body carries IP64.
PNP (sourcing) outputs are the default expectation on most European PLC input cards, so this model usually wires straight into the input with no interposing relays. The G profile letter governs only one thing - whether the switch seats correctly in your cylinder's groove - so confirm the fit against your cylinder series rather than assuming any G-series match.

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.

Clamp cylinders around a machining fixture report closed position to the PNP inputs of the machine PLC so the cycle cannot start unclamped.
Pneumatic stoppers rising between conveyor rollers signal up and down positions, letting the line controller meter product flow.
On a timber-frame nailing line, press cylinders confirm full stroke before the nail magazine indexes to the next position.
Go 3-wire PNP when your input card sources current and you want a dedicated signal line instead of a 2-wire switch in series with the load. The 2 m flying lead is the simplest termination: strip, ferrule, and land it on a terminal block, trimming the tail if the run is short. If leads get replaced often or the sensor sits where service access is awkward, an M8 or M12 connector version may suit better. The cylinder must include the magnet option, and the G profile must agree with 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.
This is a solid-state electronic switch with a PNP 3-wire output for sourcing inputs. Supply voltage is 5-30 V DC; protection is IP64 for the general type; wiring is a 2 m flying lead (code 020). It only produces a signal on a cylinder fitted with the magnet option.
Match the switch to the PLC input card: sourcing inputs take PNP, sinking inputs take NPN. PNP switches the positive supply leg to the input, which is standard on European-style cards. If you also want washdown-grade sealing, the -RW variant lifts protection from IP64 to IP68 - this model itself is the general IP64 type.
