Introduction
The LJ8A3-1-Z/AX is a capacitive proximity sensor featuring non-contact detection technology for industrial automation applications. With an 8mm cylindrical housing, this sensor reliably detects both metallic and non-metallic objects including liquids, plastics, and glass through capacitance variation principles. Its compact design enables easy installation while maintaining stable performance in challenging environments with dust or oil contamination. 31220
Operation Principle
As a target approaches the sensing face, it alters the dielectric constant of the oscillating field, triggering state changes in the internal LC circuit. Processed by advanced signal conditioning circuitry, these changes generate switch outputs without physical contact. Operating at high frequency (up to 500Hz), the sensor demonstrates fast response and precise repeatability, unaffected by target color, transparency or surface reflectivity. Compatible with 10-30VDC power supply, offering configurable NPN/PNP NO/NC outputs. 4528
Key Features
Engineered for reliability, the sensor s fully encapsulated construction provides IP67-rated protection against water, oil and corrosive substances. Adjustable detection range of 1-2mm, operating temperature from -30°C to +65°C. The optimized sensing face design minimizes mutual interference in dense mounting arrangements. Without mechanical contacts, it achieves significantly longer service life than mechanical switches and operates spark-free for hazardous areas. 71317
Typical Applications
Ideal for material detection, level control and position monitoring in packaging machines, food processing and textile equipment. Particularly suitable for harsh environments like chemical plants or cement production where dust or steam exists. Performs reliably in counting, sorting and process control on automated lines, easily integrating with PLC systems for smart manufacturing solutions. 91924
