About the AirTAC CMSJ
The AirTAC CMSJ is a reed cylinder sensor in the J profile (L-shaped body): 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 ACQ/TACQ32-100, SDA12-100, TWQ32-50, QCK32-63, QDK20-40, TN10-32 and TWH/TWM20-80 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 CMSJ 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 CMSJ 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).
Wiring: 2-wire brown (+) and blue (-).
AirTAC CMSJ FAQ
AirTAC ACQ/TACQ32-100, SDA12-100, TWQ32-50, QCK32-63, QDK20-40, TN10-32 and TWH/TWM20-80 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.
