Metal-sheet Double-feed Detector GD

From Ultra-Thin Lead Frames To Iron Sheets

The GD Double-Feed Detector allows for the detection of various metallic sheets.

Panasonic offers three (3) types of heads:

Small Object
High Precision
Long Sensing Range

Some applications are detecting overlay of washers, detecting missing tablet package in a box and detecting seam of hoop material.

Instantly Detect Distance With Time of Flight (ToF) Camera Sensors

Panasonic Time of Flight (ToF) Cameras are compact, real-time, sensing cameras based on the ToF principle. Available in indoor and outdoor models, these cameras instantly detect distance between the camera and the targeted object with depth, infrared, and color (RGB) images. The GC1 indoor model produces RGB (640x480), depth map (320x240) (640x480) images. As well, engineers no longer need separate cameras for the depth, IR, and color images with 14/16/36 bit data formats. The HC4W outdoor model has a wide 90° FOV and is used in various applications such as security, autonomous vehicles and robotics.
