Overview
The Allen-Bradley 42EF-E1EDZB-F5 is a transmitted-beam infrared photoelectric emitter engineered for reliable sensing and control in demanding industrial environments. Built on the proven RightSight platform, this sensor combines compact 18 mm cylindrical form factor with a 500 mm (20 in.) sensing distance, making it ideal for object detection, presence verification, and process control applications where long-distance, stable infrared transmission is required.
