Airtac DMSH Electronic Sensor DMSH-100-W
The AirTAC Airtac DMSH Electronic Sensor DMSH-100-W 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 with a 10 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSH Electronic Sensor DMSH-100-W
The DMSH-100-W pairs the AirTAC DMS electronic switch with the long 10 m flying lead and a trailing W code. Sensing is solid-state with a 2-wire output, powered at 10-28 V DC, and the body carries IP64 protection in this general configuration. It reports piston position by reading the magnet built into an AirTAC cylinder.
The W suffix is a code position our catalogue data does not define - it is not automatically the documented -RW waterproof IP68 upgrade, so treat the rating as IP64 until we confirm the variant from the datasheet. What is certain is the wiring: 10 m of lead for distant control points, trimmed to length during installation. The H profile governs how the switch seats in the cylinder groove and must be checked against your cylinder series before you order.

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 DMSH Electronic Sensor DMSH-100-W Is Used
Press-cylinder home signal
On a pneumatic press frame where the valve stand sits far from the actuators, the 10 m lead carries the end-of-stroke signal back to the panel; the 2-wire output drops straight into a relay input.
Test rig cylinder cycling
A durability test bench cycling magnet-fitted cylinders thousands of times benefits from the contactless solid-state element, which does not suffer the mechanical wear a reed contact eventually shows.
Multi-station fixture bank
Several clamp stations along a machining fixture each report clamped position; long 10 m leads run back to one terminal strip, keeping a single cable class across the whole fixture.
Is the Airtac DMSH Electronic Sensor DMSH-100-W the Right Switch?
This model makes sense when you need the 10 m reach and your AirTAC order or machine spec calls for the W code specifically. Everything else follows the standard 2-wire electronic recipe: series wiring into a load, no polarity to observe, 10-28 V DC. If your requirement is actually waterproofing for washdown, the correct documented option is the -RW version with IP68 - tell us and we will quote that instead. As with every switch in this class, the cylinder must have the piston magnet option and the profile letter must fit its sensor groove.
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 DMSH Electronic Sensor DMSH-100-W FAQ
Type: DMS electronic solid-state position switch. Output: 2-wire. Supply voltage: 10-28 V DC. Protection: IP64 (the W suffix is an undocumented variant we confirm from the datasheet, distinct from the -RW IP68 version). Wiring: 10 m flying lead.
We cannot confirm that from our catalogue data, so do not assume it. The documented waterproof option on DMS switches is -RW, which raises protection to IP68 for washdown and oil-mist environments. A bare -W is carried through as a factory variant and we will verify its meaning from the datasheet on request before you commit.
