Assembly Error-Proofing

To improve efficiency and accuracy in assembly applications, it is vital that parts are correct before continuing on in the process, as parts may be used to build upon each other down the line. Detecting problems as early as possible in the process prevents downtime and extra expenses. A reliable sensing solution that provides accurate feedback is needed to error-proof parts on the assembly line.


Banner’s Q4X analog sensor can give operators real-time measurement feedback to verify the part is present and correctly positioned before moving to the next operation. In this application it is crucial that both flanges around the weld nut are properly seated in order to fit correctly in the final assembly. The Q4X’s analog measurement can determine if both flanges are properly seated.

While two sensors measuring points so close together on a shiny surface may cause cross-talk and errant measurements for other sensors, a pair of Q4X sensors can be tied together in master/slave mode to automatically alternate measurement timing and completely avoid any cross-talk for reliable measurements of both flanges. The display of the Q4X gives readers immediate, real-time feedback in millimeters “mm,” ensuring that the process is running smoothly. The display could also be setup to display an analog readout in “V.”

The Q4X analog laser sensor reliably detects submillimeter distance changes and provides superior performance for continuous measurement of challenging targets from dark to reflective out to 300 mm. The easy-to-read, four-digit display helps minimize setup time and provides clear user feedback. The Q4X analog is a robust sensor, reliable in all types of industrial environments.

Q4X Versatile, Rugged Laser Distance Sensor

The versatile, rugged laser distance sensor has superior performance, detecting distance changes as small as 1 mm with a reliable sensing range of 25 to 300 mm.
