Airtac DMSGS Electronic Sensor DMSGS-NC12
The AirTAC Airtac DMSGS Electronic Sensor DMSGS-NC12 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 nc12 connection code (confirm from datasheet). It only works on a cylinder that carries a piston magnet.

About the Airtac DMSGS Electronic Sensor DMSGS-NC12
DMSGS-NC12 belongs to AirTAC's DMS family of solid-state cylinder switches. Inside is an NPN 3-wire electronic circuit that draws its supply from 5-30 V DC and signals a sinking controller input whenever the magnet in the piston arrives at the sensing position. The NC12 entry is an undocumented connection code rather than a published lead length or M8/M12 termination; ask us and we will confirm its meaning straight from the datasheet. General-type protection is IP64.
A 3-wire NPN output produces no contact bounce because there is no contact at all - the switching element is a semiconductor, so high-cycle machines see a clean, stable signal. That advantage only pays off if the switch actually fits: the G profile must correspond to the groove on your cylinder body, which we will verify against your cylinder series.

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 DMSGS Electronic Sensor DMSGS-NC12 Is Used
High-cycle sorting gates
Divider cylinders on a parcel sorter stroke hundreds of times per hour; the bounce-free semiconductor output keeps false counts off the counter.
Sinking-input PLC cards
Retrofits onto older machines whose controller inputs sink current take this NPN switch directly, avoiding the relay interposing a series-wired hookup might need.
Press-feed part presence
Feed cylinders on a stamping press confirm part advance to the line controller so the ram only cycles when both position signals agree.
Is the Airtac DMSGS Electronic Sensor DMSGS-NC12 the Right Switch?
Choose this version when your PLC input is the sinking type that an NPN switch feeds. Three wires separate the signal from the supply, which keeps the logic level tidy compared with a 2-wire unit sharing the load path. Since NC12 is not a lead length or connector we can name, request datasheet confirmation of the connection before you plan the panel wiring. Remember the switch reads nothing on its own; the cylinder must be ordered with the magnet option and the G profile must suit that body.
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 DMSGS Electronic Sensor DMSGS-NC12 FAQ
Type: electronic (solid-state) magnetic position switch. Output: NPN, 3-wire. Supply: 5-30 V DC. Protection: IP64 as a general-type unit. Wiring: the code NC12, an undocumented connection entry we will verify from the datasheet. It detects the piston magnet of a magnet-equipped cylinder only.
The DMS family is solid-state: no moving contact, no bounce, and DC supply with a polarity rule - the NPN output must meet a sinking input. A reed switch such as the CMS range instead closes a mechanical contact, tolerates AC or DC across 5-240 V, but has a finite contact life. For panel planning, also confirm what NC12 actually is before cutting harnesses.
