LJ12A3-4-JLDZ PROXIMITY SWITCH 9-250V AC NO+NC

Description

The LJ12A3-4-J/LDZ is an inductive cylindrical proximity sensor (M12 type) designed for non-contact detection of metal objects in industrial automation systems. It operates on a wide AC voltage range (9–250V AC) and provides NO + NC output, making it suitable for flexible wiring in control circuits.

It is commonly used in conveyor systems, CNC machines, packaging equipment, robotics, and industrial control panels for reliable metal position sensing without physical contact.
