Airtac DMSG Electronic Sensor DMSG-100
The AirTAC Airtac DMSG Electronic Sensor DMSG-100 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 10 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-100
An electronic, solid-state position switch in a body whose G profile is shaped to seat in the sensor groove of a matching AirTAC cylinder. Output is 2-wire, wired in series with your load like a conventional contact, on a supply of 10-28 V DC. The 100 wiring code means a 10 m flying lead, and the housing carries IP64 protection against dust and splashes.
Because this is a 10 m lead rather than a connector, you can route the cable back to a distant control cabinet and trim it to length at the terminal block. Solid-state switching gives a clean, bounce-free transition each time the piston passes. The switch only produces a signal when a magnet-equipped cylinder (the -S magnet option) reaches it; confirm the G profile against your cylinder's groove before ordering.

Which Family Do You Need?
- DMSElectronic, 2-wire / NPN / PNP, DC
- EMSMini electronic, 2-wire only, DC
- CMSReed contact, 2-wire, 5-240 V AC/DC
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.

| Consider EMS | the mini 2-wire electronic switch for tight installations |
| Consider CMS | the reed alternative for AC circuits and voltages up to 240 V |

Where the Airtac DMSG Electronic Sensor DMSG-100 Is Used
Bagging line, remote panel
A 10 m lead reaches the electrical cabinet at the far end of a fertilizer bagging line, letting the switch signal end-of-stroke to the PLC without junction boxes.
AS/RS crane mast
On a pallet AS/RS crane, the long lead runs down the mast to the base controller, flagging full retract of the clamp cylinder.
Bottle diverter gate
End-of-stroke check for a gate cylinder that diverts bottles between two lanes of a filling-plant conveyor.
Is the Airtac DMSG Electronic Sensor DMSG-100 the Right Switch?
Choose 2-wire when you want the simplest hookup: it drops in series with the load and suits relay logic or many PLC cards, accepting small leakage current in the off state. If the PLC input prefers a dedicated signal, the same G body exists as a 3-wire NPN (N) or PNP (P) version. A 10 m lead is the longest standard length, ideal when the cabinet sits far from the machine; M8 or M12 connector variants are better where you unplug during service. If the cable runs through washdown or a moving drag chain, the -RW build lifts protection to IP68. The G profile must match the cylinder groove - send the cylinder series to confirm.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (2-wire)
- ✓ Supply rail is 10-28 V DC
- ✓ Lead length or M8 / M12 connector
- ✓ Coolant or flexing? Use the RW version
Installation & Wiring Notes
- check The cylinder must carry a piston magnet — a plain cylinder cannot be sensed.
- check Slide the switch along the groove to the stop position, then lock it.
- check Keep the supply within 10-28 V DC.
- check Wire 2-wire to match the PLC input's polarity.
- check Keep the lead clear of moving parts; use the RW type where it must flex.
- check Rated IP64 — protect it beyond that rating.
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.
Airtac DMSG Electronic Sensor DMSG-100 FAQ
It is an electronic (solid-state) switch with 2-wire output, supplied from 10-28 V DC, protection rated IP64, and fitted with a 10 m flying lead. The G profile selects the body that matches the sensor groove of the cylinder.
A 2-wire model wires in series with the load just like a mechanical contact, so installation is simple, though a small leakage current flows when off. The 3-wire DMSG-N or -P types give the PLC input a cleaner switched signal, but you must match NPN or PNP to the input card.
