Key Features & Benefits:

High Precision 5mm Slot: Ensures accurate detection of small objects, edges, or marks, minimizing false readings and improving system reliability.
Reliable Transmissive Sensing: Utilizes a stable infrared LED light source and receiver across a fixed gap for dependable object presence detection, unaffected by object color or surface finish.
Fast Response Time (0.5ms max): Enables high-speed counting, precise positioning, and rapid feedback in dynamic and time-critical applications.
NPN Open-Collector Output: Provides versatile compatibility and easy integration with a wide array of control systems, PLCs, and microcontrollers.
Dark-ON Operation: The output turns ON when the light beam is interrupted, making it intuitively suitable for object detection, counting, and jam prevention.
Wide Operating Voltage Range (5 to 24 VDC): Offers flexibility for integration into diverse power supply setups, simplifying system design and reducing component count.
Compact and Robust Design: Space-saving form factor with durable PBT casing and polycarbonate lens, ensuring long-term performance and resistance to industrial environments.
Integrated Operation Indicator LED: Provides clear visual confirmation of sensing status (lights when beam is interrupted), simplifying setup, alignment, and troubleshooting.
Non-Contact Detection: Reduces wear and tear on both the detected objects and the sensor itself, extending lifespan and maintaining product integrity.
Easy Installation: Features a pre-wired 1-meter cable, simplifying wiring and accelerating integration into new or existing automated systems.

Applications:

Object Counting and Batching: Accurately counts items on conveyor belts, production lines, or in packaging machinery for inventory control and throughput monitoring.
Position Sensing: Detects the precise position of components, tools, or moving parts in automated assembly lines and robotic applications.
Edge Detection: Ideal for sensing the leading or trailing edge of films, paper, labels, or other sheet materials in printing, packaging, and converting machinery.
Limit Sensing: Acts as a reliable limit switch for mechanical movements in robotics, automated gates, and other industrial equipment.
Automated Machinery: Integration into printers, copiers, vending machines, textile machinery, and medical devices for various precise sensing tasks.
Conveyor Systems: Ensures proper product flow, prevents jams, and controls material handling by accurately detecting object presence.
Robotics: Provides essential feedback for robotic arm movements, end-effector operations, and collision avoidance.
Material Handling: Used in feeders, sorters, and pick-and-place units for precise material control and automated dispensing.
