Keyence Corporation (キーエンス, Kīensu) is a Japan-based direct sales organization that develops and manufactures equipment for factory automation, sensors, measuring instruments, vision systems, barcode readers, laser markers and digital microscopes.
An Automated Optical Inspection device. Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew).
The device usually acts as the interface of a sensor (such as a light curtain), designed to signal a safety-related event, typically when the light curtain beam's being "broken". OSSD signals are the outputs from the protective device (light curtain or scanner) to a safety relay .
These may be 2D or 3D cameras, although the vast majority of installations (2019) use machine vision 2D cameras offered by companies such as Keyence, Basler, Sick, Datalogic, COGNEX, and many others. Emerging players such as Leopard Imaging, Pickit3D, Zivid, and Photoneo are offering 3D cameras for stationary use. COGNEX recently acquired ...
User manuals and user guides for most non-trivial PC and browser software applications are book-like documents with contents similar to the above list. They may be distributed either in print or electronically. Some documents have a more fluid structure with many internal links. The Google Earth User Guide [4] is an example of this format.
Part 602 describes this type of non-contact profilometer, incorporating a single point white light chromatic confocal sensor. The operating principle is based upon the chromatic dispersion of the white light source along the optical axis, via a confocal device, and the detection of the wavelength that is focused on the surface by a spectrometer .
Remote photoelectric sensors used for remote sensing contain only the optical components of a sensor. The circuitry for power input, amplification, and output switching is located elsewhere, typically in a control panel. This allows the sensor, itself, to be very small. Also, the controls for the sensor are more accessible, since they may be ...
A SMU integrates a highly stable DC power source, as a constant current source or as a constant voltage source, and a high precision multimeter.. It typically has four terminals, two for source and measurement and two more for kelvin, or remote sense, connection.
