E3JM-R4N2 Photoelectric Switch Product Introduction (English)
The E3JM-R4N2 is an advanced photoelectric sensor engineered for object detection in industrial automation systems. Utilizing infrared beam transmission and reception technology, this non-contact sensing device provides reliable status monitoring for diverse operational scenarios. Its streamlined housing design combines functional durability with installation versatility, making it suitable for integration into various mechanical configurations.
Three key features define its technical advantages: The precision optical system ensures consistent detection accuracy across varying surface materials and colors, maintaining stable performance within its effective sensing range. Integrated ambient light immunity circuitry effectively eliminates interference from external light sources, guaranteeing operational stability under strong illumination or fluctuating light conditions. The modular construction allows multiple mounting orientations, enabling both horizontal fixation on equipment frames and vertical embedding in mechanical assemblies.
Notable environmental adaptability includes a hybrid plastic-metal housing with IP54 equivalent protection, capable of continuous operation in temperatures ranging from -25℃ to 55℃. The universal NPN/PNP output configuration ensures compatibility with mainstream industrial control systems. An accessible sensitivity adjustment dial facilitates on-site calibration, allowing technicians to optimize detection parameters according to specific application requirements.
This sensor demonstrates exceptional performance in material handling systems, production line monitoring, and equipment safety applications. Typical use cases include detecting package presence in wrapping machinery, tracking goods movement in automated warehouses, and component counting in assembly processes. The maintenance-free design minimizes lifecycle costs, while the sealed construction protects internal components from dust accumulation and liquid splashes.
Operational guidelines recommend verifying power supply compatibility, avoiding installation near strong electromagnetic sources, and maintaining optical window cleanliness. Professional mounting brackets are suggested for optimal beam alignment. When detecting reflective surfaces, field testing is advised to confirm appropriate installation distance and sensitivity settings. Regular functional checks are recommended to ensure sustained detection reliability.
