Banner Engineering Corp.The PresencePlus is a pixel-counting sensor comprising a 512 x 384 CMOS pixel array, programmable microprocessor, controller, lens, lighting, mounting bracket and cable. Banner Engineering Corp.'s sensor captures a 256-level gray-scale image, converts the image to black-and-white pixels, and compares the designated-color pixel count with user-programmed upper and lower threshold values to render a pass or fail judgment of the target. The PresencePlus is available with a choice of three C-mount lenses, a base-mounting swivel or column-mounting bracket, and either a fluorescent ring lamp or a...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueCompact Proximity SensorThe RPR-0720 from ROHM Semiconductor is a compact 2.0 mm × 1.0 mm proximity sensor for applications requiring attachment, detachment, and proximity detection.
