About the AirTAC DS1-F
The AirTAC DS1-F is a solid-state cylinder switch for SI, SU, SC and other cylinders: its transistor output turns on when the piston magnet passes. With no moving contact it switches up to 1000 times per second and has reverse polarity and surge protection. A red LED shows when it is on.
It fits AirTAC SI, SU, SC, JSI, MI, MA50(63) cylinders. It is rated IP67 (NEMA 6) and works at -10 to +70 °C.

Where the DS1-F 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 or three wires.
Choosing the Right DS1-F Configuration
Choose the output: 2-wire; 3-wire NPN (N). The 2-wire type runs on 10 to 28 V DC at up to 50 mA and connects like a reed switch; the 3-wire NPN (sinking) and PNP (sourcing) types run on 5 to 30 V DC at up to 200 mA. Match NPN or PNP to your PLC input.
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.
AirTAC DS1-F FAQ
AirTAC SI, SU, SC, JSI, MI, MA50(63) cylinders.
2-wire: 10 to 28 V DC, up to 50 mA. 3-wire NPN or PNP: 5 to 30 V DC, up to 200 mA.
A 150 mm lead ending in an M8 (C08) or M12 (C12) 3-pin male connector. The female cable is ordered separately. 020, 030, 050 and 100 are fixed leads of 2, 3, 5 and 10 m.
The 2-wire type wires like a reed switch in series with the load. The 3-wire types need a separate supply and give an NPN (N) or PNP (P) transistor output with a lower voltage drop and higher current.
No. You can order a single piece. Orders are processed and handed to the carrier within 3-5 business days.
