About the AirTAC CMSG

The AirTAC CMSG is a reed cylinder sensor in the G profile: its reed contact closes when the piston magnet passes. It switches 5 to 30 V AC/DC up to 100 mA (10 W max.) and needs no supply of its own. The standard type has an LED; the high-temperature type (-H) has none and works up to +125 °C.

It fits AirTAC SDA, ACQ/TACQ, SAU, TCL/TCM, TWQ, TWH/TWM, QCK, MD/MK, TR, STW, MCK, AQK/BAQK, HFZ, HFY, HFP, HFK, HFKL and HFKP cylinders in the slot (MCK with the F-MCK40G holder); PB/PBR, MI/TMI, MF, MG, MA/MAC, MBL, MCK and TWG cylinders with an F-MQ band; SC and SGC cylinders with an F-SC SH bracket; ACT cylinders with an F-ACT SH bracket. It has a high-flex cable and is rated IP64; it works at -10 to +70 °C (high-temperature type -10 to +125 °C).

Where the CMSG Is Used

End-of-stroke sensing

Signals when the piston reaches either end, so the next step can start.

Mid-stroke positions

Slide the sensor along the slot to detect any intermediate position.

PLC and relay inputs

Wires straight to a PLC input or relay with two wires.

Choosing the Right CMSG Configuration

Choose the type: standard (with LED, -10 to +70 °C) or high temperature (-H, no LED, -10 to +125 °C). The high-temperature type has no connector option.

Choose the connection: 2 m lead (020); 3 m lead (030); 5 m lead (050); 10 m lead (100); M8 connector, 0.5 m lead (M08). The M8 and M12 versions end in a male quick connector; the female cable (F-EC, for example F-ECM08B020 for M8, 2-core, 2 m) is ordered separately.

Wiring: 2-wire brown (+) and blue (-).

On round-barrel cylinders order the F-MQ band with the barrel code (for example F-MQA32 for an aluminum Ø32 barrel, F-MQS16 for a stainless Ø16 barrel); on SC and SGC tie-rod cylinders order the F-SC SH bracket for the bore (F-SC32SH for Ø32 and Ø40).

AirTAC CMSG FAQ

AirTAC SDA, ACQ/TACQ, SAU, TCL/TCM, TWQ, TWH/TWM, QCK, MD/MK, TR, STW, MCK, AQK/BAQK, HFZ, HFY, HFP, HFK, HFKL and HFKP cylinders in the slot (MCK with the F-MCK40G holder); PB/PBR, MI/TMI, MF, MG, MA/MAC, MBL, MCK and TWG cylinders with an F-MQ band; SC and SGC cylinders with an F-SC SH bracket; ACT cylinders with an F-ACT SH bracket.

5 to 30 V AC/DC, up to 100 mA and 10 W max.

020, 030, 050 and 100 are fixed leads of 2, 3, 5 and 10 m. M08 and M12 are an M8 or M12 male quick connector on a 0.5 m lead; M08010, M08020 and M08030 (M12010 to M12030) put it on a 1, 2 or 3 m lead. The female cable is ordered separately.

The CMS reed switch needs no supply, switches AC or DC and suits simple circuits. The DMS electronic sensor has no moving contact, switches up to 1000 Hz and offers NPN or PNP outputs.
