Control Pin
Normal Operation
For normal operation do not connect the control pin. Hold
and synchronize features can be used for special
applications.
Hold
To inhibit sensor operation and hold the output to its present
state connect the control pin (2) to 0V DC. The sensor will
not transmit or receive ultrasonic pulses until this voltage is
removed from the control pin. Switching output models will
be latched and analog output models will hold their value
during this period.
Synchronize
To synchronize the transmission of ultrasonic pulses
between several sensors connect the control pins together.
This feature reduces the potential for sensor crosstalk
between models that are mounted in close proximity to one
another.
