About the AirTAC CS1-E
The AirTAC CS1-E is a reed cylinder switch for SE cylinders: its normally open reed contact closes when the piston magnet passes. It switches 5 to 240 V AC/DC up to 100 mA (10 W max.), needs no supply of its own and has no leakage current. The standard version has a red LED; the X version has none.
It fits AirTAC SE cylinders. It is rated IP67 (NEMA 6) and works at -10 to +70 °C.

Where the CS1-E Is Used
End-of-stroke sensing
Signals when the piston reaches either end, so the next step can start.
Mid-stroke positions
Slide the switch along the barrel to detect any intermediate position.
PLC and relay inputs
Wires straight to a PLC input or relay with two wires.
Choosing the Right CS1-E Configuration
Choose the type: 2-wire, red LED; 2-wire, no LED (X).
Choose the connection: 2 m lead (020); 3 m lead (030); 5 m lead (050); 10 m lead (100); M8 connector, 150 mm lead (C08). The C08 version ends in a 3-pin male straight connector; the mating female cable is ordered separately.
