Airtac DMSE Electronic Sensor DMSE-C12
The AirTAC Airtac DMSE Electronic Sensor DMSE-C12 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.

About the Airtac DMSE Electronic Sensor DMSE-C12
The DMSE-C12 belongs to AirTAC's DMS family of solid-state electronic position switches. It clips into the groove of a magnet-fitted AirTAC cylinder and reports piston position electrically - on its own it senses nothing. This code reads as the E profile, a 2-wire output, and the connection token C12 at the wiring position. That token is a factory variant AirTAC has not documented publicly; we read its definition straight from the datasheet once you enquire. Supply is 10-28 V DC with IP64 protection on the general type.
Solid-state switching means no mechanical contact to chatter or wear out, so the switch tolerates frequent duty cycles better than a reed alternative. Note that the E profile is a fit code: it has to sit correctly in your cylinder's sensor groove, so check the profile letter against your cylinder model before you 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 | DMSE · 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 DMSE Electronic Sensor DMSE-C12 Is Used
Fixture clamp confirmation
Signals full clamp closure on pneumatic fixtures in a machining cell, wired in series into a 24 V DC interlock loop.
Compact automation modules
End-of-stroke feedback inside tightly packed actuator modules, where a series-wired 2-wire switch keeps the wiring count down.
Sorter gate positioning
Confines gate cylinders on a parcel sorter to their retracted position so diverters fire only when the lane is clear.
Is the Airtac DMSE Electronic Sensor DMSE-C12 the Right Switch?
Decide by circuit first. This is the 2-wire version: it wires in series like a conventional contact, which keeps panel work simple. If your controller prefers a dedicated signal wire, look at the DMSE-N or DMSE-P 3-wire types instead. The C12 wiring entry is a code position we cannot decode from published data - quote it exactly as printed and we will pull its definition from the datasheet. The E profile must match the sensor groove of your cylinder, and that cylinder needs the built-in magnet option for anything to be detected.
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 DMSE Electronic Sensor DMSE-C12 FAQ
It is a solid-state electronic position switch with a 2-wire output, supplied from 10-28 V DC and rated IP64 in the general build. The wiring code C12 is a factory connection variant that is not described in our published data; we verify its meaning in the datasheet when you enquire.
Yes, two things. The cylinder must be ordered with the built-in magnet option, and the switch's E profile has to match the sensor groove on that cylinder so it seats correctly. Without the magnet piston the switch has nothing to detect.
