Airtac DMSH Electronic Sensor DMSH-NC08
The AirTAC Airtac DMSH Electronic Sensor DMSH-NC08 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 npn 3-wire output on 5-30 V DC. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-NC08
An electronic piston-position sensor in AirTAC's DMS series, the DMSH-NC08 uses a solid-state element rather than a mechanical reed. The letter N specifies an NPN 3-wire output for sinking PLC inputs, H is the groove-fit profile, and the C08 token is a factory connection code whose exact termination we will confirm from the datasheet on request. Supply span is 5-30 V DC; the standard housing carries IP64.
Because it is three-wire, the switch hands the controller a referenced signal instead of behaving like a contact in series with the load, which keeps the input state unambiguous. It still needs a partner: an AirTAC cylinder built with the magnet option, whose groove accepts the H profile. Confirm both the cylinder fit and the C08 detail before you wire it in.

|---|---|
| H | Profile letter: the mounting / groove type that fits a particular cylinder body. This family offers E, G, H, J. It is a fit code, not a performance grade. |
| N | Output: NPN 3-wire. Blank is 2-wire, N is NPN 3-wire, P is PNP 3-wire. |
| 08 | See datasheet. 020 / 030 / 050 / 100 are 2 / 3 / 5 / 10 m flying leads; M08 and M12 are M8 / M12 connector versions. |

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 · NPN 3-wire · 5-30 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-NC08 Is Used
Assembly cell slide verification
A transfer unit's slide cylinder, ordered with the magnet option, signals 'home' and 'extended' to the cell PLC; the solid-state output suits the frequent indexing of an assembly station.
Test rig actuator positioning
On an R&D test bench, the referenced three-wire signal lets engineers log each actuator end position precisely, with the C08 termination matched to the rig's interface once confirmed.
Controller input-card sensing
Panels built around sinking digital inputs take the NPN output directly - one wire to supply, one to the input, one common - keeping panel wiring tidy.
Is the Airtac DMSH Electronic Sensor DMSH-NC08 the Right Switch?
This code combines an NPN output with the C08 connection designation - a catalogue variant we do not document in detail, so ask us and we will pull the datasheet. If your panel prefers a sourcing input, the P version is the equivalent PNP part. Electronic switches of this class run on DC only and watch polarity; if your circuit swings between AC and DC or you want a contact-style switch instead, a CMS reed model covers 5-240 V AC/DC. The H profile must match the cylinder groove regardless of which family you choose.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (NPN 3-wire)
- ✓ Supply rail is 5-30 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 5-30 V DC.
- check Wire npn 3-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-NC08 FAQ
Yes: DMS electronic (solid-state) type, NPN 3-wire output, 5-30 V DC supply, IP64 protection, and the C08 connection code, which we will verify from the datasheet for you. Sensing distance and similar values are not published here - confirm from the datasheet.
It is a factory connection designation in the AirTAC catalogue; the meaning is not in our published data, so we do not guess. Send an RFQ and we will confirm the exact termination from the official datasheet before you order.
