The “LJ12A3-4-Z/BX” is an inductive proximity sensor that detects metal objects within a 4mm range. It operates on a DC 6-36V power supply and has an NPN (Normally Open) digital output, meaning it completes a circuit to the signal line when it detects metal. These sensors are used in industrial automation for non-contact switching, control, and detection
MODULE compatible Arduino to control 4 motors DC or 2 stepper motors and have 2 connections for servomotors. This shield uses pins D3 to D12 for operation (direction, speed, etc).
