Airtac CMSE Magnetic Reed Sensor CMSE-030
The AirTAC Airtac CMSE Magnetic Reed Sensor CMSE-030 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 with a 3 m flying lead. It only works on a cylinder that carries a piston magnet.

About the Airtac CMSE Magnetic Reed Sensor CMSE-030
This CMSE-030 is a reed-type position switch for AirTAC cylinders built with the magnet option. Its 2-wire reed contact signals piston position without any amplifier or polarity to worry about. The 030 wiring code means a 3 m flying lead, and the general-type housing is rated IP64 for 5-240 V AC or DC.
Three metres of lead buys routing freedom: you can reach a remote junction box or run the cable away from moving parts before it terminates. As with every CMS switch, the E profile letter selects the mounting shape that matches the cylinder groove - verify the pairing against your cylinder model or ask us.

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. |
| 030 | 3 m flying lead. 020 / 030 / 050 / 100 are 2 / 3 / 5 / 10 m flying leads; M08 and M12 are M8 / M12 connector versions. |

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?

- 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.

Where the Airtac CMSE Magnetic Reed Sensor CMSE-030 Is Used
Palletizer clamp verify
On a bag palletizer, the 3 m lead reaches the control cabinet from the clamp cylinder, and the reed contact proves the arms have gripped the layer.
Fill-head lift signal
A bottling line raises and lowers its filling heads between bottles; this switch confirms the head stack is fully up before crates advance.
Gantry axis end-stop
A CNC loading gantry uses the reed switch at each axis end; the extra lead length lets the cable route clear of the moving beam.
Is the Airtac CMSE Magnetic Reed Sensor CMSE-030 the Right Switch?
Pick this reed switch over an electronic DMS/EMS model when the control voltage is AC or you prefer a contact with no polarity to observe; for high-frequency DC counting on a PLC, a 3-wire NPN or PNP DMS switch signals more cleanly. The 3 m lead is the practical middle length - shorter than the 5 m and 10 m options but long enough to clear the machine frame. If the cable will flex continuously, compare with an IP68 -RW electronic switch. The cylinder needs its magnet option and an E-profile groove; confirm both.
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-030 FAQ
Sensor type: magnetic reed. Output: 2-wire, polarity-free. Supply voltage: 5-240 V AC or DC. Protection: IP64. Wiring: 3 m flying lead. Values not listed here, such as switching current, should be confirmed from the datasheet.
Flying leads are the simplest and most economical termination: cut to length and land on a terminal block. If you expect to unplug the switch for cylinder service or want to swap cables without rewiring, a CMS E-profile unit with an M8 or M12 connector is the better maintenance choice. Either way the piston needs the magnet option.
