Upstream Photo Eyes

Also known as Choke Feed: two eyes which are mounted on the customer’s conveyor upstream of the machine to monitor product flow. These eyes automatically pause the machine in the absence of containers and restart it once product arrives at the machine. The eyes feature time delays for both on and off functions and for fine tuning the machine in relation to the line operation.
Benefit: prevents machine cycling when no product is present and insures non-round containers enter the machine without jamming.
