The Allen Bradley 42CB-P2LNA-M4 is an 18 mm high-speed sensor designed for reliable object detection in fast-paced industrial environments. This compact, cylindrical sensor features a polarized retroreflective design with a visible red light, allowing for precise sensing even in challenging conditions. It offers manual adjustment to fine-tune performance, and supports NPN output with DC load or DC output selectable options for versatile integration. The sensor connects via a 4-pin micro quick disconnect, housed in a durable plastic body with an 18 mm mounting diameter. With a response time of just 0.5 milliseconds, it can detect objects as close as 3 mm, while effectively operating up to distances of 2800 to 3750 mm depending on the target. This sensor is available through BSP Automation, providing a dependable solution for automation systems requiring fast and accurate presence detection.
