Airtac DMSH Electronic Sensor DMSH-C12
The AirTAC Airtac DMSH Electronic Sensor DMSH-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 DMSH Electronic Sensor DMSH-C12
This is an AirTAC DMS electronic position switch: a solid-state sensor, not a reed contact. Its 2-wire output reads the piston magnet of an AirTAC cylinder ordered with the built-in magnet option. Profile H sets the groove fit for the cylinder body. Supply voltage is 10-28 V DC and the general-type housing is rated IP64. The wiring token C12 is a factory connection variant that is not documented in our data; we will confirm its exact meaning from the datasheet on request, so no lead length or connector type is claimed here.
Wiring-wise, a 2-wire switch sits in series with the load, so it drops into an existing relay or PLC input the same way a mechanical limit switch would - handy when retrofitting an older machine. Switching current, voltage drop and sensing distance are not published here; confirm them from the datasheet. Before ordering, match the H profile letter against the sensor groove of your cylinder series, because a wrong profile will not seat.

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 | DMSH · 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 DMSH Electronic Sensor DMSH-C12 Is Used
Gripper homing on a pick-and-place arm
Fitted to the body of a compact gripper cylinder on a small-parts transfer arm, it confirms open and closed positions in a 24 V DC control loop.
Clamp confirmation on machining fixtures
Wired in series with the fixture interlock chain, the switch proves the clamp cylinder has reached its retracted seat before cycle start.
Lift-table lower limit
Mounted on the lift cylinder of a warehouse scissor table, it signals the full-down position to the pallet conveyor controls.
Is the Airtac DMSH Electronic Sensor DMSH-C12 the Right Switch?
Choose the DMS family when the control circuit is DC and you want contact-free, bounce-free switching; the reed-type CMS instead suits AC circuits or a wide 5-240 V supply. This unit is 2-wire - simplest to hook up - while NPN or PNP 3-wire DMS versions give a dedicated, cleaner signal to a PLC input card. Lead options elsewhere in the range run from 2 to 10 m flying leads or M8/M12 connectors; the C12 code on this model is undetermined, so verify it before purchase. The switch only works on a cylinder fitted with the 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 DMSH Electronic Sensor DMSH-C12 FAQ
Type: electronic (solid-state) position switch. Output: 2-wire. Supply: 10-28 V DC. Protection: IP64 general type. Wiring: code C12 is a factory connection variant we confirm from the datasheet; fit is set by the H profile groove code.
The H profile letter is a fit code that must match the sensor groove of your cylinder body - it is not a performance grade. And yes: the cylinder must carry the built-in magnet option. Without a magnetic piston there is no field to sense, so the switch will never change state.
