Airtac DMSH Electronic Sensor DMSH-100
The AirTAC Airtac DMSH Electronic Sensor DMSH-100 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
DMSH-100 is an AirTAC DMS electronic position switch in the general type: solid-state sensing, a 2-wire output, IP64 protection and a 10 m flying lead. It detects the piston magnet inside a suitably equipped AirTAC cylinder and signals when the piston arrives at the switch position. Supply voltage is 10-28 V DC.
The 10 m lead is the key specification here - it is intended for runs to a control panel or cabinet located far from the actuator, and it can be shortened to the exact route length rather than joined or extended. As a 2-wire device it wires in series like a conventional limit switch, which keeps the panel side straightforward. The H in the code is the groove-fit profile: it must correspond to the sensor groove of your cylinder, so confirm the match against the cylinder series you are using.

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 Is Used
Gate confirmation on a long conveyor line
diverters and gates are often tens of metres from the electrical room; the 10 m lead on a magnet-fitted AirTAC cylinder reaches the panel run directly, with the excess trimmed along the cable tray.
Palletiser clamp signal
On a palletising cell, clamp cylinders signal grip-close position back to the PLC; the 2-wire series hookup into an interposing relay keeps the low-voltage side simple.
Sluice gate position on a treatment plant
A penstock or sluice driven by a long-stroke AirTAC cylinder uses the 10 m lead to report open or closed to a remote control kiosk, powered from a 10-28 V DC supply.
Is the Airtac DMSH Electronic Sensor DMSH-100 the Right Switch?
Pick the DMSH-100 when the distance between the cylinder and your control cabinet is too long for the 2 m or 5 m leads - 10 m of pre-attached cable avoids mid-run joints. It stays a 2-wire electronic unit, so there is no NPN/PNP decision; if you later want a cleaner dedicated PLC input signal, look at the 3-wire NPN or PNP DMS versions. This is the general type at IP64 - for washdown or moving cable tracks step up to the -RW IP68 variant. Ordering requires a magnet-equipped cylinder and a profile letter that matches its 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 FAQ
It is an electronic solid-state switch with a 2-wire output, wired in series with your load, and supplied at 10-28 V DC. Protection is IP64. Wiring is a 10 m flying lead that can be cut to your route length. No NPN or PNP polarity applies to this version.
A flying lead is a fixed specification choice: the 10 m version suits cylinders far from the panel and lets you cut to length without adding joints. An M8 or M12 connector variant is the better pick when you need to unplug the sensor for service. Both are the same sensing technology - it is a wiring-access decision, not a performance one.
