LJ12A3-4-Z/BX NPN / LJ12A3-4-Z/BY PNP Inductive Proximity Sensor حساس معادن

The LJ12A3-4-Z/BX NPN / LJ12A3-4-Z/BY PNP Inductive Proximity Sensor حساس معادن is a compact, non-contact metal detection sensor designed for industrial automation and control applications. This family of sensors delivers reliable sensing of ferrous and non-ferrous metal targets without physical wear, offering long service life in repetitive switching tasks.Both NPN and PNP output variants are available, enabling compatibility with sinking or sourcing input circuits in PLCs, controllers, and relay logic. The sensors are intended for straightforward installation in constrained spaces and are suitable for position sensing, presence detection, end-of-travel monitoring, and part counting in assembly, packaging, and machine tool equipment.Constructed with a rugged housing and sealed sensing face, the sensors resist dust and incidental moisture commonly encountered on factory floors. Their simple electrical interface and standardized wire/color coding make integration into existing control systems efficient, while built-in switching behavior provides consistent, repeatable responses in automated sequences.When selecting between the LJ12A3-4-Z/BX (NPN) and the LJ12A3-4-Z/BY (PNP) models, match the output polarity to your system requirements and wiring conventions to ensure proper operation. The sensors are compatible with typical industrial power supplies and protective wiring practices, and they deliver dependable, low-maintenance metal detection for a wide range of industrial sensing tasks.
