DXP-L21GSEB EMERSON TOPWORX PLC Programmable Logic Controller -20°C To 60°C
DXP-L21GSEB DescriptionThe Emerson DXP-L21GSEB is a highly reliable industrial-grade photoelectric sensor from the DXP series, designed for precise and stable object detection in challenging automation environments. Engineered for long-distance sensing, it features a modulated infrared LED light source paired with a PNP transistor output, providing excellent immunity to ambient light interference. The sensor's IP67-rated robust housing ensures reliable performance in applications exposed to dust, moisture, and oil, making it a trusted solution for positioning, counting, and presence detection in material handling, packaging, and assembly systems.DXP-L21GSEB Features
Long Sensing Distance: Provides a reliable, extended detection range, enabling flexible mounting in large-scale or hard-to-reach installations.
High Noise Immunity: Utilizes a modulated infrared light source and advanced signal processing to effectively reject interference from ambient light (e.g., sunlight, fluorescent lamps) for stable operation.
Robust Industrial Design: Features an IP67-rated enclosure, making it dust-tight and protected against temporary immersion, suitable for harsh industrial settings.
Easy Installation and Alignment: Equipped with a stable sensing indicator (red LED) for easy setup and alignment, reducing installation time and improving accuracy.
NPN/PNP Output Selection (Typically Configured): Models in this series often come in both NPN (sinking) and PNP (sourcing) output variants; the "B" in the part number typically denotes a PNP (sourcing) output, compatible with a wide range of PLCs and controllers.
Short-Circuit and Reverse Polarity Protection: Built-in protective circuits safeguard the sensor from accidental wiring errors and electrical faults, enhancing system durability.
DXP-L21GSEB Material & Application
Material: The sensor housing is constructed from high-grade, glass-reinforced polyamide (PA) or similar engineering plastic, offering high impact resistance and chemical stability. The sensing window is made of scratch-resistant, optically clear polycarbonate. Internal electronics are protected by potting compound for vibration and moisture resistance.
Primary Applications:
Conveyor line object detection and counting
Pallet presence and positioning in logistics
Bottle/can detection in bottling and packaging lines
Automated warehouse storage and retrieval systems
Machine guarding and access control
Roll diameter measurement in web processing
