What is open collector output?
A transistor is used in the output. When the sensor detects
a person or object, the transistor turns on and current flows
from the collector to the emitter, outputting a signal.
When open collector output is used, the current flow
and voltage applied to the load connected to the
output can be set as desired. This enables wide
range of use in sequencers and other devices.
