4 873P Ultrasonic Single & Dual Output Sensors
varies depending on the type(s) of sensors used (see below). The
target must be positioned at the same distance from each
synchronized sensor; the target position should overall be flat.
When mounted correctly, the synchronized sensors perform like a
single sensor with an extended detection angle.
Please note that sensor response times will increase
proportionally to the number of synchronized sensors.
How it Works:
Connect Pin 2 (white) to all sensors to be synchronized.
All sensors will trigger at the same time. Any eventual crosstalk
signal related to a longer sensing distance will be ignored. An
external synchronization pulse controls the sensors.
All minimum distances depend on target distance and material.
“T” is the pulse time period applied on the SYNC wire, and “Width”
refers to the pulse width.

ATTENTION
If a hazardous condition can result from
unintended operation of this device, access to the
sensing area should be guarded.
Solid-state devices can be susceptible to radio
frequency (RF) interference depending on the
power and the frequency of the transmitting
source. If RF transmitting equipment is to be used
in the vicinity of the solid-state devices, thorough
testing should be performed to assure that
transmitter operation is restricted to a safe
operating distance from the sensor equipment and
its wiring. IMPORTANT
