Airtac DMSHS Electronic Sensor DMSHS-P020
The AirTAC Airtac DMSHS Electronic Sensor DMSHS-P020 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 DMSHS Electronic Sensor DMSHS-P020
The DMSHS-P020 is a solid-state electronic position switch from AirTAC's DMS range. Clipped into the sensor groove of a magnet-equipped AirTAC cylinder, it signals a PNP 3-wire sourcing output when the piston reaches it. Supply is 5-30 V DC, the general-type housing is sealed to IP64, and power comes in on a 2 m flying lead, the shortest standard cable in the series.
Three wires, not two, are the point here: the switch feeds its own supply separately and hands the controller a clean, bounce-free signal instead of sitting in series with the load. The H profile letter is a fit code - it has to match the groove in your cylinder body, so confirm the pairing before you order. For washdown cells, the -RW build raises protection to IP68.

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-P020 Is Used
PLC end-of-stroke feedback
Gives a packaging clamp cylinder a discrete PNP input signal so the controller confirms full closure before releasing the next cycle.
Compact pick-and-place head
Mounted in the groove of a small-bore cylinder on a gantry, with the 2 m lead reaching a nearby junction box.
Diverter gate interlock
A short-stroke cylinder swings a sorting gate on a parcel line and the switch reports gate-home to the line PLC.
Is the Airtac DMSHS Electronic Sensor DMSHS-P020 the Right Switch?
Pick this PNP version when the PLC input card sources current; NPN sinks and the two are not interchangeable. The 2 m lead suits short runs and can be trimmed to length, while M8 or M12 connector codes cost a little more but unplug for fast sensor swaps during service. The S that follows the profile letter is a factory variant - ask us and we will check its exact meaning in the datasheet. Remember: no magnet piston, no signal.
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-P020 FAQ
It is an electronic solid-state switch with a PNP 3-wire output running on 5-30 V DC. Protection is IP64 in the general type, and connection is a 2 m flying lead. It only detects a piston that carries the factory magnet option.
A PNP output sources voltage into a sinking PLC input, so the signal stays clean with no series leakage, and the solid-state element never bounces or wears out. A CMS reed switch is simpler and runs on 5-240 V AC/DC, but its mechanical contact has a finite life. Match polarity to your input card.
