Airtac DMSHS Electronic Sensor DMSHS-C12
The AirTAC Airtac DMSHS Electronic Sensor DMSHS-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 with a c12 connection code (confirm from datasheet). It only works on a cylinder that carries a piston magnet.

About the Airtac DMSHS Electronic Sensor DMSHS-C12
AirTAC's DMSHS-C12 is an electronic, solid-state cylinder switch with a 2-wire output that reads the piston magnet of a compatible AirTAC cylinder. It runs on 10-28 V DC and carries an IP64 housing. C12 is a factory connection code not decoded in our current data, so its exact definition will be confirmed from the datasheet on request.
Because there is no mechanical reed inside, the output stays stable through high-cycle duty and never suffers contact bounce. The profile letter governs only how the body seats in the cylinder's sensor groove; match it to your cylinder series before ordering.

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 | 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 DMSHS Electronic Sensor DMSHS-C12 Is Used
Multi-station rotary table
Around an eight-station rotary indexer, the switches confirm each clamp cylinder is down before the table is allowed to index.
AGV lift column
On an automated guided vehicle's lift cylinder, the 2-wire signal tells the onboard controller the mast is fully lowered before travel.
Assembly press jaw detect
Mounted on the jaw cylinder of a bench assembly press, it verifies the part is gripped before the operator can trigger the stroke.
Is the Airtac DMSHS Electronic Sensor DMSHS-C12 the Right Switch?
Stay with the electronic DMS line for DC panels and fast cycling; move to a CMS reed switch if the circuit is AC or you prefer a contact with no polarity. As a 2-wire part it connects in series with the load, keeping panel wiring minimal. Before designing the harness, let us verify what C12 specifies from the datasheet. Standard IP64 protection handles ordinary factory conditions - choose -RW for an IP68 washdown build. Remember: no magnet in the piston, no signal, and the profile has to seat correctly in the groove.
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 DMSHS Electronic Sensor DMSHS-C12 FAQ
It is a solid-state electronic switch, 2-wire output, 10-28 V DC supply, IP64 protected. The C12 connection detail is a factory code we will confirm from the datasheet on request.
A CMS reed switch has a mechanical contact and accepts 5-240 V AC or DC with no polarity. This DMS unit is electronic: DC only, no bounce, better suited to rapid cycling - but voltage and polarity must match your circuit.
