 Circuit Definition & Working Logic (3-port / 2-port)

   1. 3-port Type (VM13x, Most Popular)· Port 1(P): Air supply inlet

     -- Port 2(A): Control output

     -- Port 3(R): Exhaust port

     -- Normally Closed NC: Unactuated → P cut off from A, A connected to R

     -- Normally Open NO: Unactuated → P connected to A, A cut off from R

   2. 2-port Type (VM12x)

     -- Port 1(P): Fluid input

     -- Port 2(A): Control output

     -- Normally Closed logic: Air passage opens when pressed, cuts off after release

     -- VM130U / VM120U: Short 2.5mm stroke plunger

  2. Pushbutton Type (Manual Jog Operation)

     -- VM132 / VM122: Flat standard pushbutton

     -- VM132Y / VM122Y: Yellow mushroom head for emergency stop & high visibility

     -- VM132G / VM122G: Green indicator pushbutton

  3. Roller Lever Type (Stroke & Limit Detection)

     -- VM131 / VM121: Standard straight roller lever

     -- VM131U / VM121U: Short travel roller lever

     -- VM133 / VM123: One-way anti-rebound roller lever

  4. Optional Extra Actuators
