@autologic.hub: I How to Control a Pneumatic Cylinder with a Proximity Sensor ⚡🔧 Step-by-step electropneumatic relay wiring: • PNP proximity switch powered via Brown (+24V) and Blue (0V) • Black signal wire triggers relay coil at Pin 14 (Pin 13 to 0V) • Bridge Pin 14 to Pin 12 (Common) • Pin 8 (NO Contact) powers the 24V solenoid valve • Solenoid valve return line connects to 0V • Metal detected extends cylinder; removing object retracts it automatically!
