Product Overview
The Gongxin Sensor Proximity Switch LXJ8(3SG)-3202, manufactured by Shanghai No.2 Machine Tool Electrical Apparatus Factory, is a high-performance inductive proximity switch designed for industrial automation. Featuring a metal housing and non-contact detection technology, it is widely used in machinery manufacturing, textiles, papermaking, and metallurgy for positioning, counting, speed measurement, and safety protection. Its robust design ensures reliable operation in harsh industrial environments.113
Technical Features
Operating on high-frequency oscillation principles, the LXJ8(3SG)-3202 detects metal targets by generating eddy currents, converting signals into switch outputs. With built-in reverse polarity and surge protection, it supports a broad voltage range (DC10-30V), offers a sensing distance of 1.5-2mm, and responds at 500-1000Hz frequencies. The IP67-rated housing resists oil, dust, and moisture, while an LED indicator provides real-time status monitoring. Its wear-free design significantly reduces maintenance needs.11421
Applications
Ideal for CNC machines, conveyor systems, and packaging equipment, this switch replaces mechanical limit switches in high-precision or demanding conditions. For instance, in steel mills, it ensures continuous production by detecting metal components; in food processing, its sealed construction withstands washdown environments. Compatible with PLCs, it supports PNP/NPN output configurations for flexible integration.11622
Advantages
Optimized circuitry and materials enhance the LXJ8(3SG)-3202 s anti-interference capability, temperature stability (-25℃~+70℃), and ease of installation. Its compact M18 cylindrical design suits space-constrained applications, and a one-year warranty underscores quality commitment. Users can select normally open or closed models to match control requirements.11921
