Airtac DMSHS Electronic Sensor DMSHS-N050
The AirTAC Airtac DMSHS Electronic Sensor DMSHS-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 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-N050
This DMSHS-N050 belongs to AirTAC's DMS range of solid-state cylinder sensors. The N code gives an NPN 3-wire output for a PLC or controller input, and the unit detects the magnet inside a piston of an AirTAC cylinder specified with the magnet option. It runs from a 5-30 V DC supply, is sealed to IP64, and the 050 suffix in the wiring position specifies a 5 m flying lead.
Where a reed switch closes a mechanical contact that can bounce and eventually wear out, this electronic design switches with no moving parts, so it suits machines that index many times a minute. Note that the H profile letter is a fit code for the cylinder's sensor groove, not a rating - verify the match against your cylinder drawing. The S after the profile is an undocumented code position; we will pull its exact detail from the datasheet once you ask.

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 · 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-N050 Is Used
CNC fixture clamping
Clamp cylinders on a CNC machining fixture must report closed position before cycle start; the NPN signal feeds the machine tool's checked input without an intermediate relay.
Palletizer pusher position
In a palletizing cell, pusher cylinders square each layer; the 5 m lead spans the run from the cylinder on the frame to the I/O rack in the control cabinet.
Gate cylinder on an access system
An automated industrial gate drive uses the switch to prove the cylinder is fully retracted before the controller releases the interlock.
Is the Airtac DMSHS Electronic Sensor DMSHS-N050 the Right Switch?
Choose between technologies by circuit: a reed CMS accepts 5-240 V AC or DC, while this electronic DMS needs a DC supply and the correct NPN or PNP polarity. Three-wire NPN hands your controller a dedicated signal rather than a series-wired 2-wire loop. A 5 m lead suits frames where the terminal box sits far from the cylinder; connector versions (M8/M12) are available for tool-free swaps. For wet or oily zones pick the -RW IP68 variant. Confirm the H profile seats in the cylinder groove and that the piston carries a magnet.
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-N050 FAQ
It is a solid-state electronic switch, not a reed. Output is NPN 3-wire, supply range is 5-30 V DC, the protection rating is IP64, and the 050 code supplies a 5 m flying lead. Match the H profile to your cylinder's groove before ordering.
Only on models built with the magnet option, and only where the profile letter matches the sensor groove - the H here is a fit code, not a grade. Send your cylinder series with the RFQ and we will confirm the correct profile, plus the meaning of the S variant position, from the datasheet.
