产品描述（英文）
The E3K51-R2N1 square-shaped relay-embedded photoelectric switch is an industrial-grade proximity sensor featuring built-in relay output. With compact dimensions of approximately 50×50×18mm (varies by model), this device utilizes infrared beam technology for non-contact object detection. The NPN normally-open output configuration supports DC 6-36V operating voltage, providing reliable switching for automation control systems. Its robust construction ensures stable performance in challenging environments including vibration-prone or temperature-fluctuating conditions. The product s modular design allows flexible installation via mounting brackets or direct panel fixation. 192127
技术优势（英文）
This photoelectric switch distinguishes itself with advanced optical filtration technology that minimizes ambient light interference. The integrated relay module delivers 0.1A contact capacity, eliminating need for external amplifiers in most applications. Self-diagnostic LEDs visually indicate power status and detection activity. Models are available with diffuse-reflective, retro-reflective or through-beam sensing modes to accommodate different detection requirements. The housing s reinforced corners and sealed joints provide mechanical protection in high-impact scenarios. These features make it particularly suitable for material handling systems, automated assembly lines and safety interlock applications. 222428
使用注意事项
建议在强电磁干扰环境加装金属屏蔽罩，避免与高频设备并行布线。安装时应确保检测面与被测物保持垂直，定期清洁光学窗口防止灰尘积聚影响灵敏度。对于反光率低的黑色物体检测，建议预留20%的检测距离余量。产品不支持酸碱腐蚀环境下的长期使用，特殊工况需选用耐化学腐蚀型号。141928
