Airtac DMSH Electronic Sensor DMSH-N050
The AirTAC Airtac DMSH Electronic Sensor DMSH-N050 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 with a 5 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-N050
This DMSH-N050 pairs AirTAC's electronic switch family with a generous 5 m flying lead, letting you route the cable away from hot or moving machine sections back to the control cabinet. The NPN 3-wire output works from a 5-30 V DC supply and sinks into a PLC input card; the body is IP64.
Solid-state switching means no reed contact to wear out and no signal bounce on rapid cycling - a real advantage on palletisers and other high-rate machines. The sensor only sees anything once it is mounted on a cylinder with the built-in magnet option, and the H profile must seat in that cylinder's groove.

|---|---|
| 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. |

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-N050 Is Used
Palletiser arm check
On a palletising cell, the 5 m lead lets the switch sit deep in the machine frame while its NPN output reaches the cabinet, confirming the layer pusher is home.
High-rate press feed
A metal press feed with short strokes cycles the piston magnet hundreds of times a minute; the solid-state output answers without the bounce a reed contact would show.
Lab motion rig
A test-rig slide driven by an AirTAC cylinder uses the switch as an end-of-travel reference, with the long lead keeping electronics outside the moving envelope.
Is the Airtac DMSH Electronic Sensor DMSH-N050 the Right Switch?
Decide between families by circuit first: a CMS reed unit handles 5-240 V AC or DC simply, while this DMS electronic model is DC-only but bounce-free for fast cycling. On a 5-30 V DC system with a sinking PLC input, the NPN 3-wire output here is the clean choice. The 5 m lead suits runs that pass near moving parts or reach a distant cabinet; if you prefer tool-free swaps, look at the M8/M12 connector builds instead. Standard sealing is IP64; the -RW version lifts that to IP68. Whichever you pick, the H profile has to fit the cylinder groove and the piston must carry the factory magnet.
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-N050 FAQ
Type: electronic solid-state. Output: NPN 3-wire. Supply: 5-30 V DC. Wiring: 5 m flying lead. Protection: IP64 in the general build. It detects the piston magnet of an AirTAC cylinder fitted with the magnet option and nothing else.
It is ideal when the cable must route around moving sections or reach a distant cabinet, and you can trim it to length on site. If the sensor is unplugged often for service or replacement, an M8 or M12 connector version saves rewiring - both are legitimate specification choices.
