About the AirTAC CMSE
The AirTAC CMSE is a reed cylinder sensor in the E 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 SE/BSE32-125, SAI/TSAI32-100, SAI125-200, ACE12-125 and JSI32-125 cylinders. 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 CMSE 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 CMSE 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, 3 m lead (M08030); M12 connector, 0.5 m lead (M12). 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 (-).
AirTAC CMSE FAQ
AirTAC SE/BSE32-125, SAI/TSAI32-100, SAI125-200, ACE12-125 and JSI32-125 cylinders.
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.
No. You can order a single piece. Orders are processed and handed to the carrier within 3-5 business days.
