Updated: 2 days ago

The SICK PLOC2D-631 is a 2D robot guidance sensor, listed from USD 6,100. This review covers its full specifications, design, integration, applications and price, so you can decide whether it fits your automation project.
Quick Verdict
The SICK PLOC2D-631S is a stand-alone 2D robot guidance sensor with a 1.3 MP imager (1,280 x 1,024 px) that locates parts by shape comparison with an accuracy of +/-0.5 px and +/-0.1 degrees. It finds the first part in under 0.5 s and each further part in under 100 ms, and sends the X and Y position and the rotation to the robot controller for pick and place tasks. It takes S-mount lenses with focal lengths from 9.6 mm to 25 mm and covers fields of view from about 100 x 80 mm to 1,200 x 960 mm. The housing measures 108 x 63 x 46 mm, weighs 430 g and is rated IP65 with the optics cover fitted. It runs on 12 to 24 V DC and communicates via TCP/IP, PROFINET and EtherNet/IP. It is listed from USD 6,100.
