产品优势
区别于传统机械开关，该产品采用全电子式工作原理，响应速度更快且无触点损耗。方形外壳设计支持多种安装方式，埋入式或非埋入式安装均不影响检测性能。产品提供明确的LED状态指示，便于现场调试和维护。简单的三线制接线方式（棕色接正极/蓝色接负极/黑色信号输出）降低了安装复杂度。71423
English Introduction
The LJ2L-15G-4/121 proximity switch (also labeled as LJ2L15G4121) is an eddy-current based non-contact sensor designed for metallic object detection. With a 15mm sensing range and compact rectangular housing, it provides reliable position sensing in automated systems without physical contact. The device operates on 6-36V DC power supply and delivers 400mA switching current for controlling external loads. 15
Featuring epoxy-encapsulated construction, this inductive sensor maintains stable performance in challenging environments (-20°C to 70°C) with resistance to water splash and dust. Its oscillation-based detection principle ensures fast response to metal targets while eliminating mechanical wear. The product s three-wire connection (brown+/blue-/black signal) and status LED simplify installation and troubleshooting processes. Typical applications include machine tool positioning, conveyor monitoring, and safety interlock systems across manufacturing industries. 71423
