LJ8A3-1-Z/AX電容式接近開關LJ8A31ZAX
產(chǎn)品概述
LJ8A3-1-Z/AX是一款高性能電容式接近開關，采用非接觸式檢測技術，適用于工業(yè)自動化領域的多種物體檢測需求。該產(chǎn)品通過電容感應原理工作，能夠可靠檢測金屬和非金屬物體，包括液體、塑料、玻璃等材料。其緊湊的圓柱形設計（直徑8mm）便于安裝，同時具備良好的環(huán)境適應性，可在粉塵、油污等復雜工況下穩(wěn)定運行。1312
工作原理
當被測物體接近傳感器感應面時，會改變原有電場的介電常數(shù)，從而觸發(fā)內部振蕩電路狀態(tài)變化。這種變化經(jīng)過信號處理后轉換為開關量輸出，實現(xiàn)無接觸檢測。產(chǎn)品采用高頻振蕩技術，響應速度快（最高500Hz），重復定位精度高，且不受目標物顏色、透明度或表面反光狀態(tài)影響。支持直流10-30V寬電壓供電，輸出模式可選NPN/PNP常開或常閉配置。1428
產(chǎn)品特點
該接近開關具有優(yōu)異的抗干擾性能和長期穩(wěn)定性，采用全封閉樹脂封裝結構，達到IP67防護等級，具備防水、防油和耐腐蝕特性。檢測距離為1-2mm（可調），工作溫度范圍-30℃至+65℃。特殊設計的感應面能有效抑制相鄰傳感器干擾，適用于高密度安裝場景。產(chǎn)品無機械磨損部件，使用壽命遠超傳統(tǒng)機械開關，且不會產(chǎn)生電火花，可安全用于防爆環(huán)境。3713
應用領域
廣泛應用于包裝機械、食品加工、紡織設備等行業(yè)的物料檢測、液位控制和位置定位。特別適合在化工、水泥等存在粉塵或蒸汽的惡劣環(huán)境中使用，可穩(wěn)定檢測傳送帶上的塑料瓶、紙箱或金屬部件。在自動化生產(chǎn)線中可用于計數(shù)、分揀和流程控制，也可集成到PLC系統(tǒng)實現(xiàn)智能化管理。91924
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
