Airtac DMSG Electronic Sensor DMSG-050
The AirTAC Airtac DMSG Electronic Sensor DMSG-050 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 5 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSG Electronic Sensor DMSG-050
This DMSG-050 is a solid-state magnetic position switch for AirTAC cylinders equipped with the built-in magnet option. Its 2-wire output connects in series with the load and switches on 10-28 V DC; sealing is IP64. Wiring comes as a 5 m flying lead, giving extra routing freedom between machine and cabinet on larger frames.
A long lead can save a junction box: run the cable straight back to the panel and cut it to length on installation. The G in the code is a mounting-fit code matched to the cylinder's sensor groove, never a performance grade, so check it against your cylinder series before committing to the order.

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.
| This switch | DMSG · 2-wire · 10-28 V DC |
|---|---|
| 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 |
| Mounting parts | F-MQ (round body), F-ACT (tie-rod) |
Where the Airtac DMSG Electronic Sensor DMSG-050 Is Used
High-cycle pick-and-place
Solid-state switching keeps up with the rapid extend-retract cycle of a pick-and-place cylinder on an electronics assembly gantry, with no contact bounce to filter.
Multi-station dial table
Two 5 m leads run cleanly from clamps on opposite sides of a rotary indexing table to a single central cabinet, with no junctions needed.
Test rig position feedback
Used on a leak-test rig where the 2-wire output lights a panel lamp once the clamping cylinder has sealed the part.
Is the Airtac DMSG Electronic Sensor DMSG-050 the Right Switch?
Decide by circuit first: solid-state DMS switching suits DC control systems with frequent cycling, since there is no reed contact to bounce or wear out, while a CMS reed switch is the pick for AC supplies or mixed 5-240 V circuits. With 2-wire wiring the switch sits in series with the load like a mechanical contact; 3-wire NPN/PNP models feed a PLC input with a cleaner signal. The 5 m tail removes splice boxes on big machines, but if sensors are unplugged at changeovers, a connector version is tidier. Need IP68 rather than IP64? Specify -RW. Above all, profile G must fit the groove of your magnet-equipped cylinder.
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-050 FAQ
The DMSG-050 is a solid-state electronic switch with a 2-wire output, it operates on 10-28 V DC, its general-type sealing is IP64, and the connection is a 5 m flying lead. Figures such as switching current, voltage drop and response time are not published here - confirm them from the datasheet.
Solid-state DMS and EMS switches handle DC loads without contact bounce or mechanical wear, which suits frequent cycling; a CMS reed switch instead offers a polarity-free mechanical contact that accepts 5-240 V AC or DC and suits simpler or legacy circuits. Both read the piston magnet the same way, so the real decision is your control circuit.
