About the AirTAC CM3
The AirTAC CM3 is a 3/2-way valve (the HD two-way selector is 5/3-way) with an aluminum body that takes 13 different heads. The basic plunger (B), roller lever (R), one-way roller lever (L) and vertical roller (V) heads are worked by a cam or dog on the machine, so the valve signals a position or the end of a stroke. The rocker lever (Y), turn-release latching button (PL), extended push button (PP), flush push button (PF), mushroom push button (PM), mushroom button with guard (PMS), large mushroom button with guard (PMX), selector switch (HS) and two-way selector switch (HD) 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 CM3L/CM3V/CM3R/CM3Y heads are metal for a long life. The PMS and PMX mushroom buttons have a metal guard so they are not pressed by accident. 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 CM3 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.
Guarded buttons
PMS and PMX have a metal guard round the mushroom button.
Choosing the Right CM3 Configuration
Choose the head. Machine-operated: basic plunger (B), roller lever (R), one-way roller lever (L) and vertical roller (V). Hand-operated: rocker lever (Y), turn-release latching button (PL), extended push button (PP), flush push button (PF), mushroom push button (PM), mushroom button with guard (PMS), large mushroom button with guard (PMX), selector switch (HS) and two-way selector switch (HD).
Then the port: M5 (05) Cv 0.11, 1/8" (06) Cv 0.14, 1/4" (08) Cv 0.84. A larger port passes more air.
Push-button and selector heads (PP, PF, PM, PMS, PMX, HS, HD) need a color letter: R red, G green, B black, Y yellow. 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.
