Product Description

The LJ18A3-8-Z/BY sensor, also known as the inductive proximity switch LJ18A3, is an 18mm-diameter DC 3-wire sensor designed for industrial automation, machinery, and assembly applications. Operating within a 10-30V DC range, it provides a single output channel with NPN/PNP configuration, directly interfacing with control modules without requiring additional interfaces. The device offers an 8mm detection range for metallic targets and functions reliably in temperatures from -25°C to +70°C. Its compact, rugged housing ensures resistance to vibration and environmental stress, while the absence of moving parts enhances durability. Though lacking built-in communication protocols, its simple wiring and high switching accuracy make it ideal for position sensing in conveyor systems or robotic arms. Limitations include restricted non-ferrous material detection and no onboard diagnostics.
