Airtac DMSH Electronic Sensor DMSH-PC08
The AirTAC Airtac DMSH Electronic Sensor DMSH-PC08 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. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-PC08
This DMSH-PC08 is an AirTAC electronic cylinder switch with PNP 3-wire signalling, built to detect the magnet in a suitably equipped piston. Supply voltage is 5-30 V DC and the general-type housing carries IP64. Its C08 wiring token is a factory connection variant that our catalogue does not define; we will confirm precisely what C08 specifies from the datasheet.
Solid-state switching means no worn or bouncing contacts, which suits fast repetitive cycling - the trade-off is a DC-only supply and correct polarity, which the 3-wire PNP format enforces toward sourcing PLC inputs. As always, the H profile letter only describes the groove fit, never a quality level; verify it against your cylinder series.

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 · PNP 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-PC08 Is Used
Robotic weld-cell clamp
In a weld cell, the sensor confirms the fixture clamp is retracted so the robot arm can swing in without fouling.
Connector-style retrofit
With the C08 connection, this variant suits machines being rewired for pluggable sensor drops; confirm the exact C08 interface from the datasheet before matching it to your harness.
Laboratory actuator bench
On a materials-testing bench, it marks the start position of a loading cylinder so each test cycle begins from the same point.
Is the Airtac DMSH Electronic Sensor DMSH-PC08 the Right Switch?
Go with this unit if your control system is DC-based with sourcing (PNP) input cards; the C08 connection should be matched to your harness once we have confirmed it from the datasheet. For machines that get serviced often, a defined M8 or M12 connector may suit better, while flying-lead types win on cost and cut-to-length routing. If your panel runs on AC, a CMS reed switch spanning 5-240 V AC/DC is the alternative. Any DMS or CMS switch needs the cylinder's magnet option and a groove-matching profile.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (PNP 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 pnp 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-PC08 FAQ
This is a solid-state DMS switch with a PNP 3-wire output, fed from 5-30 V DC and sealed to IP64. Its C08 connection token is not defined in our data - we treat it as a factory variant and confirm the exact interface from the datasheet before you order.
Functionally yes on a DC circuit: the electronic output does not bounce and suits fast cycling, while a reed switch like the CMS runs on 5-240 V AC or DC with a mechanical contact. Match the PNP output to your PLC input card, and remember polarity matters here.
