External Product Sensors
The G20i supports NPN, PNP and Push-Pull sensor types. When
connected, the sensor will send a print trigger signal to the G20i when the
leading edge of a product passes the sensor.
When using an external product sensor, the product sensor type
(page 6-42), print delay (page 6-44) and print mode (page 6-46) must be
set.
NPN Product Sensor Connection
CAUTION: Turn off the G20i and disconnect the power before
making any wiring connections.
