    Banner’s Q4X versatile laser sensor is ideal for presence/absence detection even in challenging applications with small height changes such as confirming a small black target is present on a shiny metal part. The washers should be present in the cast aluminum engine block, and if the Q4X detects a slight height difference, even as small as 1 mm, it will send a signal to alert operators a rubber washer is missing or there are multiple washers present. The Q4X can detect duplicate rubber washers with its unique windowing capability while in foreground suppression mode.

  30. Error-Proofing Assembly Applications

    Banner’s K50 Series of single-point pick-to-light sensors are a simple, easy-to-use error-proofing solution in assembly applications. In this application, the job light is Green while the job input is active, indicating the correct bin for the next pick. The presence of the assembler’s hand initiates an output change of state, turning the job light red. The job light above the next pick location will then turn Green.

  31. Package Inspection Using Diffuse-Mode Laser Sensors

    A WORLD-BEAM QS18LD diffuse-mode laser sensor can be used to accurately inspect each package as it passes on a conveyor. The sensor emits a visible Class 1 laser sensing beam, focused on the piece of tape used to seal the package. When the top of the box is closed and sealed correctly, the tape will return the sensing beam back to the receiver.

  32. Incorrect Pick Signal

    The EZ-LIGHT K50 sensor lights above a bin to show the assembler which part to pick. If the assembler reaches into a different bin, that bin's EZ-LIGHT K50 sensor lights up in the designated warning color—in this example, red— to indicate the error.

  33. Part Pick Verification from a Wide Bin

    The EZ-LIGHT K50 sensor in retroreflective mode indicates that the next part in the assembly sequence is the sunroof. When the operator selects the sunroof from its wide bin, the K50 detects the pick.

  34. Part Pick Verification for Order Fulfillment

    In an order fulfillment operation for a candy distributor, bins are equipped with EZ-LIGHT K50 sensors connected to a process controller programmed with the order. Based on the order, the K50 illuminates to show which items to pick.
