Namco Controls (Highland Heights, OH) has introduced the EP200 Series of photoelectric sensors for use in a variety of industrial applications. Surface-mount electronics make them suitable for presence/absence detection.
The SmartImage Sensor from DVT (Norcross, GA) inspects for presence/absence, orientation, position and size. FrameWork 1.2, a Windows®-based software user interface, allows subpixel measurement and math computation skills.
The LUT 3-8 luminescence sensor from SICK Optic-Electronic (Eden Prairie, MN) combines high switching frequency and a fast response time with the convenience of a semiconductor UV light source and a more compact design.
