Airtac CMSE Magnetic Reed Sensor CMSE-C08
The AirTAC Airtac CMSE Magnetic Reed Sensor CMSE-C08 is a genuine CMS 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 5-240 V AC/DC. It only works on a cylinder that carries a piston magnet.

About the Airtac CMSE Magnetic Reed Sensor CMSE-C08
The CMSE-C08 is an AirTAC reed position switch whose connection code is C08. In the standard ordering code this position would carry a flying-lead length or an M8/M12 connector, but C08 is a factory variant whose exact meaning is not published in our data, so we confirm it from the datasheet on request before you order. What is certain: it is a 2-wire magnetic reed switch, a mechanical contact with no polarity, rated for 5-240 V AC or DC and sealed to IP64. It detects the piston magnet of an AirTAC cylinder built with the magnet option.
Because the contact is mechanical and isolated, the C08's connection detail does not change the electrical behaviour - the switch still closes cleanly into AC or DC circuits. The E profile letter sets the groove fit and must be matched to your cylinder series, so send us the cylinder model together with your enquiry and we will verify both the fit and the C08 definition.

A reed contact switches a wide window, 5-240 V AC or DC, which is why it suits AC circuits and relay logic. IP64. The CMS range has no RW / IP68 option - that belongs to DMS and EMS. Switching distance, response time, current rating, voltage drop, LED behaviour, contact life, weight and dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| E | 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. |
| 08 | See datasheet. 020 / 030 / 050 / 100 are 2 / 3 / 5 / 10 m flying leads; M08 and M12 are M8 / M12 connector versions. |
| (blank) | Standard version. On a CMS the suffix -H is the high-temperature version — do not confuse it with the H profile letter. |
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.

| Consider EMS | the mini 2-wire solid-state switch (DC only) |

Where the Airtac CMSE Magnetic Reed Sensor CMSE-C08 Is Used
OEM machine replacement parts
Servicing an imported machine whose BOM lists CMSE-C08 by exact code. Matching the original connection variant avoids re-terminating the customer's existing harness on the clamp cylinders.
Retrofit into legacy panel wiring
An older production machine with pre-terminated sensor drops needs a switch that plugs into the existing C08 connection arrangement, keeping the 110 V AC control circuit untouched.
Position check on a test rig
A leak-test fixture uses the reed contact to confirm the clamping cylinder is fully home before the test cycle starts; the wide 5-240 V range lets it drive the rig's existing relay logic.
Is the Airtac CMSE Magnetic Reed Sensor CMSE-C08 the Right Switch?
Specify the CMSE-C08 only when your drawing, OEM spec or existing installation calls for this exact code - the C08 connection is something we verify from the datasheet rather than interpret. Electrically it behaves like every CMS reed switch: 2-wire, 5-240 V AC/DC, IP64, mechanical contact. If you simply need a defined lead or connector, the CMSE with 020-100 leads or M8/M12 connectors are documented alternatives. As with all of these sensors, the cylinder must have the built-in piston magnet, and the E profile must seat in 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 5-240 V AC/DC
- ✓ Lead length or M8 / M12 connector
- ✓ High temperature? Use the -H 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 5-240 V AC/DC.
- check A reed contact suits AC or DC; observe the load limits on the datasheet.
- 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 CMSE Magnetic Reed Sensor CMSE-C08 FAQ
It is a reed (mechanical contact) position switch, 2-wire, rated 5-240 V AC or DC, protected to IP64, and polarity-free like all CMS reed switches. The C08 token sits in the connection position of the ordering code; its exact meaning is not in our published data, so we confirm the precise connection detail from the AirTAC datasheet on request.
No - M08 in the AirTAC code is the documented M8 connector option, while C08 is a separate connection code whose definition we do not assume. Never order it as a like-for-like M8 part without checking. As for the cylinder: it must carry the built-in piston magnet option, and the E profile must match that cylinder's sensor groove - send both model numbers and we will confirm the fit.
