Robotic gripper having proximity sensor with off-set sensor |
摘要 |
A proximity sensing assembly for sensing the proximity of a metallic workpiece to a work holding device includes Hall-effect sensor. The magnetic field generated by the magnet is altered when a metallic workpiece is in close proximity to a magnet. Due to an offset relationship between the sensor and the poles of the magnet, the polarity detected by the Hall-effect sensor is analogous to a reversal when a metallic workpiece is proximate the magnet rather than simply detecting a change in strength. Thus the polarity detected by the Hall-effect sensor sends an clearly defined signal indicating the presence or absence of a workpiece in the work holding device.
