Bulletin 871P DC Inductive Proximity Can Motion Sensor
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Description
Bulletin 871P inductive proximity can motion sensors are self
contained solid state devices. These devices are designed
specifically for sensing motion of size 202 to 704 metal cans
without physical contact.
The 871P can sensor family combines rugged construction and
superior sensing capability to provide long lasting durability and
performance in hostile manufacturing and filling environments.
