SA-3015LA接近开关/SA3015LA
产品概述
SA-3015LA是一款高性能的圆盘式接近开关，采用非接触式检测原理，适用于工业自动化场景中的位置检测和控制。该产品通过感应金属物体的接近实现开关动作，无需机械接触，有效减少磨损和故障率。其设计紧凑，安装便捷，可广泛用于机床、冶金、化工、纺织等行业的限位、计数、定位等应用场景。产品具有防水、防震特性，可在-25℃至+70℃环境下稳定工作。48
工作原理与特性
该接近开关基于电磁感应原理，内置振荡电路产生交变磁场，当金属目标进入感应区域时会产生涡流效应，从而触发开关状态变化。提供DC10-30V或AC90-250V两种供电版本可选，输出方式支持NPN/PNP常开/常闭配置。检测距离为15mm（±10%），响应频率达100Hz，能快速识别移动物体。外壳采用工程塑料材质，防护等级达IP67，可抵抗油污、粉尘等工业环境干扰。三线制接线设计（棕/蓝/黑线分别对应电源正/负/信号输出），接线方式简单明确。27
应用场景
SA-3015LA适用于自动化产线的物体存在检测、传送带速度监控、机械部件定位等场景。例如在包装设备中用于检测产品有无，在仓储系统中实现堆垛高度监测，或在流水线上完成精密计数。其圆盘式结构特别适合空间受限的安装环境，如电梯门控、液压缸位置反馈等场合。产品兼容PLC控制系统，可通过信号输出驱动继电器或指示灯，实现更复杂的逻辑控制功能。121
Technical Specifications
The SA-3015LA proximity sensor is a non-contact inductive switch with 15mm detection range (±10%). Operating on DC/AC power supply (10-30VDC or 90-250VAC), it features PBT housing with IP67 protection against water and dust ingress. The three-wire configuration (brown/blue/black for V+/V-/signal) supports both NPN and PNP output modes, enabling flexible integration with control systems. With 100Hz response frequency and -25°C to +70°C operating temperature range, this disc-type sensor ensures reliable metal object detection in industrial automation applications including positioning, counting and speed monitoring. The compact design facilitates installation in confined spaces while maintaining stable performance under vibration conditions.417
Functional Advantages
This sensor eliminates mechanical contact wear through electromagnetic field sensing technology, significantly extending service life compared to traditional limit switches. The optimized coil design provides consistent detection accuracy even with variations in target material composition. Standard M30 mounting threads allow for tool-free installation, while the LED status indicator simplifies troubleshooting. Typical applications include CNC machine tool limit protection, conveyor belt monitoring, and automated assembly line control where fast response and environmental resistance are critical. The product is compatible with most PLC input modules without requiring additional signal converters.1224
Typical Configurations
Multiple variants are available including different housing materials (plastic/metal), connection types (cable/pigtail/connector), and output configurations (2-wire/3-wire). The LA series specifically indicates 15mm sensing distance with AC/DC compatibility. For special requirements like high temperature or chemical exposure environments, customized solutions can be provided with modified housing materials and sealing designs. The product s modular construction enables quick replacement and maintenance in field applications. All versions share the same core detection technology ensuring consistent performance across the product family.615
