Airtac DMSJ Electronic Sensor DMSJ-PC08
The AirTAC Airtac DMSJ Electronic Sensor DMSJ-PC08 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 pnp 3-wire output on 5-30 V DC. It only works on a cylinder that carries a piston magnet.

About the Airtac DMSJ Electronic Sensor DMSJ-PC08
DMSJ-PC08 belongs to AirTAC's DMS range of solid-state electronic switches and carries a PNP 3-wire output for a magnet-equipped AirTAC cylinder piston. The wiring position of the code reads C08, a factory connection variant whose exact termination is not defined in our catalogue data, so we confirm it from the datasheet on request. Supply span is 5-30 V DC and the housing is IP64.
Three-wire switching keeps the ON/OFF level clean at the PLC input because the sensor, not the load loop, defines the signal - a practical advantage over a series-wired 2-wire part on long runs. As always, the J profile is a groove-fit code: match it to your cylinder body and quote both part numbers so we can verify the C08 variant together.

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 | DMSJ · PNP 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 DMSJ Electronic Sensor DMSJ-PC08 Is Used
Press-feed part present
Verifying that a feed cylinder has fully advanced before the press stroke is enabled, with the PNP output driving a sourcing PLC input.
AGV lift-mast position
Lift-up signal on automated guided vehicle masts, where the C08 connection variant on this code will be checked against the vehicle's harness drawing.
Harness-built machine retrofits
Panels pre-terminated for special connection codes - we confirm exactly what this variant terminates in before your harness is fabricated.
Is the Airtac DMSJ Electronic Sensor DMSJ-PC08 the Right Switch?
This model makes sense where the controller demands a sourcing three-wire sensor; choose N instead of P for a sinking input card. Because C08 is a real catalogue code position with an unpublished meaning, treat the termination as unconfirmed until we check the datasheet - do not assume a lead length or connector style. General builds are IP64; for washdown or flexing cable tracks the -RW version raises that to IP68. The switch reads nothing unless the cylinder carries the factory magnet option, and the J profile has to seat in the matching groove.
Quick checklist
- ✓ Cylinder has a piston magnet
- ✓ Profile letter fits your cylinder groove
- ✓ Output matches the PLC input (PNP 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 pnp 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 DMSJ Electronic Sensor DMSJ-PC08 FAQ
Type: electronic solid-state. Output: PNP 3-wire. Supply: 5-30 V DC. Protection: IP64. Wiring: the C08 connection code, a factory variant whose termination we confirm from the datasheet rather than guess.
It does not. M8 connector codes are written M08, so C08 is a separate factory connection variant not described in our published data. Tell us the cylinder series and panel drawing and we will verify the termination and the J profile groove fit from the datasheet.
