The Applications
1. Precision Part Detection on Automated Conveyor Lines
In automated conveyor operations, consistent part detection is essential to avoid stoppages and process errors. This sensor is typically installed along conveyor paths to confirm the presence and movement of boxes, trays, or components. Its energetic infrared sensing allows objects to be detected directly, eliminating the need for reflectors and simplifying mechanical layouts. The narrow detection angle helps separate closely spaced items, while the fast response supports higher belt speeds. Combined with a sealed housing, it performs reliably in dusty, vibrating production areas common in logistics, packaging, and general manufacturing.
2. Accurate Position Verification in Assembly and Pick-and-Place Systems
Assembly lines and pick-and-place stations require precise confirmation that parts are correctly positioned before the next operation begins. This sensor is used to verify component placement, fixture alignment, or tool position without physical contact. Its infrared detection reduces wear compared to mechanical switches, ensuring long-term consistency. Flexible switching modes allow easy adaptation to different control logic. The compact M18 form factor supports installation near tooling or robotic arms, enabling reliable feedback even in tight spaces where accurate positioning is critical to product quality.
3. Product Presence Monitoring in High-Speed Packaging Machines
Packaging equipment depends on precise detection to ensure products are correctly filled, sealed, or labeled. This sensor is commonly applied at transfer points to confirm product presence before each packaging step. The focused sensing area minimizes false signals from machine structures or background surfaces. High switching frequency and quick response enable synchronization with fast machine cycles. Its durable enclosure and temperature tolerance support continuous operation in packaging environments where vibration, heat, and airborne particles are common, helping maintain consistent throughput and reduce rejects.
4. Non-Contact Detection in Automated Storage and Material Handling Systems
Automated storage and material handling systems rely on sensors to detect carriers, bins, or pallets as they move through transfer stations and storage lanes. This model provides reliable non-contact detection, reducing maintenance compared to mechanical limit switches. Infrared sensing performs consistently across different materials and surface finishes. Electrical protection and rugged construction enhance reliability in electrically noisy industrial settings. By delivering accurate position feedback to control systems, the sensor helps prevent misalignment, supports smooth material flow, and improves overall system efficiency.
