Airtac EMSG G-Type Electronic Sensor EMSG-C12
The AirTAC Airtac EMSG G-Type Electronic Sensor EMSG-C12 is a genuine EMS 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.

About the Airtac EMSG G-Type Electronic Sensor EMSG-C12
The EMSG-C12 is a mini electronic position switch from AirTAC's EMS range. Its solid-state, 2-wire body clips into a cylinder groove and reads the piston magnet of an AirTAC cylinder built with the magnet option. Supply is 10-28 V DC and the general housing carries IP64 protection. The wiring token C12 is a factory connection variant that is not defined in our catalogue data, so confirm its exact termination from the datasheet before ordering.
Because the output is 2-wire, it wires in series with the load much like a mechanical contact, which keeps panel wiring simple. One caution: the C12 code position is a factory variant we will confirm from the datasheet on request, and the G profile must match the sensor groove of your cylinder or the switch will not seat.

Every EMS is 2-wire on a 10-28 V DC supply; there is no NPN / PNP version. 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.
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 | EMSG · 2-wire · 10-28 V DC |
|---|---|
| Consider DMS | the full electronic range, including NPN / PNP 3-wire outputs |
| 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 EMSG G-Type Electronic Sensor EMSG-C12 Is Used
Cam timing on a packaging machine
Mount two EMSG-C12 switches in the grooves of a horizontal sealing cylinder to confirm open and closed positions before the film feed advances.
Fixture clamps in a machining cell
Interlock the spindle so it cannot start until every pneumatic clamp on the CNC fixture reports fully closed.
Compact slides in an electronics line
The mini body suits the narrow grooves of small-bore slides used to index PCB trays between test stations.
Is the Airtac EMSG G-Type Electronic Sensor EMSG-C12 the Right Switch?
Pick EMS when panel space or groove width demands the smallest body - it is solid-state and DC powered only, unlike a CMS reed switch that runs on 5-240 V AC or DC. The 2-wire output suits a simple series circuit; if your PLC input prefers a dedicated signal line, look at a 3-wire DMS NPN or PNP model instead. The G profile is a fit code, not a grade, so match it to your cylinder's groove, and remember the cylinder itself must carry the built-in magnet option.
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 EMSG G-Type Electronic Sensor EMSG-C12 FAQ
It is a solid-state electronic switch with a 2-wire output, supplied from 10-28 V DC and protected to IP64 as a general-type unit. The C12 wiring code is a connection variant not defined in our data - request the datasheet to confirm its termination.
Only M8 and M12 tokens are documented as connectors in this range. C08 and C12 are factory codes whose meaning is not published here, so we confirm them from the datasheet on request rather than guess. Note also that the switch senses nothing on its own - the cylinder must be ordered with the built-in magnet.
