The AirTAC Airtac DMS Electronic Cylinder Switches DMSH-PM08010 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 pnp 3-wire output on 5-30 V DC with a m8 connector. It only works on a cylinder that carries a piston magnet.
AirTAC's DMSH-PM08010 is a solid-state magnetic position switch that reads the piston magnet of a magnet-fitted cylinder and switches a 2-wire DC output. The supply window is 10-28 V DC and the housing carries IP64 sealing. Its wiring code decodes to an M8 connector plus a 1 m lead - enough cable to reach a distant junction box while still letting maintenance unplug the sensor instead of cutting a loom.
A 1 m pigtail solves a classic panel problem: the switch sits mid-machine, the nearest I/O point is out of arm's reach, and a 0.5 m stub falls short. Being a 2-wire electronic unit, it drops into the circuit in series with the load, the way a mechanical contact would. Note that H sets the mounting profile, which has to suit the groove on your cylinder - we check the pairing against your series on request.

2-wire versions run 10-28 V DC; NPN / PNP 3-wire versions run 5-30 V DC. 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.

| 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. |
| P | Output: PNP 3-wire. Blank is 2-wire, N is NPN 3-wire, P is PNP 3-wire. |
| M08010 | M8 connector. 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.
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.

| 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) |
The 1 m M8 lead reaches the I/O node on a palletiser's gate cylinder, and the 2-wire output confirms full retract before the gate logic releases.
On a machining centre's pneumatic fixture clamp, the sensor reports clamp-complete to the PLC so the cycle cannot start with a loose workpiece.
A rinse-station lift cylinder on a bottling line signals home position through this switch, its series wiring keeping the retrofit panel simple.
Stay with this 2-wire electronic DMS when the control circuit is DC and the machine cycles hard - no contact bounce, no wearing reed blade. For a cleaner PLC signal choose the 3-wire NPN or PNP DMS variants instead, matched to your input card's polarity. If the panel runs AC, or you need the wide 5-240 V AC/DC span, the reed-type CMS family takes over. The extra metre of M8 cable here buys reach; the -RW code would buy IP68 waterproofing in oily or sprayed zones. Whatever you pick, the profile letter must seat correctly in the groove of a cylinder built with the magnet.
Quick checklist
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.
Electrical set: electronic solid-state type, 2-wire output, 10-28 V DC supply, IP64 protection, and an M8 connector fitted with a 1 m lead. Detailed limits such as switching current are in the datasheet - ask us for a copy.
The connector lets a technician unplug a faulty sensor and swap it without rewiring the cabinet, and spare cables can be stocked separately. On this model the pigtail is 1 m; 0.5 m, 2 m and 3 m M8 versions exist elsewhere in the DMS range.
