About the AirTAC S3
The AirTAC S3 is a 3/2-way valve with an aluminum body that takes 12 different heads. The basic plunger (B), vertical roller (V), roller lever (R) and one-way roller lever (L) heads are worked by a cam or dog on the machine, so the valve signals a position or the end of a stroke. The long handle (C), short handle (D), rocker lever (Y), mushroom push button (PM), extended push button (PP), flush push button (PF), turn-release latching button (PL) and selector switch (HS) heads make it a hand valve.
It is a poppet valve: it seals tightly and switches cleanly. No lubrication is needed and it mounts in several positions. The S3C/S3D/S3Y/S3R/S3L/S3V heads are metal for a long life. It works on air filtered to 40 µm from 0 to 1.0 MPa (0-145 psi), proof pressure 1.5 MPa, -20 to +70 °C.

Where the S3 Is Used
Position and limit detection
Plunger and roller heads are worked by a cam or dog and switch the air signal at the end of travel.
Manual control panels
Push buttons, selectors and levers start, stop or switch an air circuit by hand.
Air logic without electrics
Sends pilot signals to air-piloted valves and cylinders.
Choosing the Right S3 Configuration
Choose the head. Machine-operated: basic plunger (B), vertical roller (V), roller lever (R) and one-way roller lever (L). Hand-operated: long handle (C), short handle (D), rocker lever (Y), mushroom push button (PM), extended push button (PP), flush push button (PF), turn-release latching button (PL) and selector switch (HS).
Then the port: M5 Cv 0.14, 1/8" (06) Cv 0.45, 1/4" (08) Cv 0.67. A larger port passes more air.
Push-button and selector heads (PM, PP, PF, HS) need a color letter: R red, G green, B black. The PL latching button is red only and takes no letter. M5 ports have no thread code; on 1/8" and 1/4" ports PT is standard, G (BSPP) is marked G.

Machine-operated: basic plunger (B), vertical roller (V), roller lever (R) and one-way roller lever (L). Hand-operated: long handle (C), short handle (D), rocker lever (Y), mushroom push button (PM), extended push button (PP), flush push button (PF), turn-release latching button (PL) and selector switch (HS).
R red, G green, B black. Only the push-button and selector heads take one; the PL latching button is red and has no letter; the other heads have no color code.
