System Configuration and Functions
 Reference: Bidirectional Muting
Shown below is an example of bidirectional muting with 4 retro-reflective photoelectric sensors.
It can be used for applications of workpiece approaching from both directions.
Connect outer muting sensors A1 and A2 to the muting input 1 and inner muting sensors B1 and B2 to
the muting input 2.
1. Workpiece approaching from the left
2. Muting from an opposite direction is available as well
This arrangement example uses regressive reflection type E3Z-R series as a muting sensor.
Arrangement must take mutual interference into account.
Muting sensors must be installed so that a distance D3 between muting sensors A1 and A2 should be
smaller than workpiece length L.
As a muting sensor, a transmission or regressive reflection type photoelectric switch, proximity
switch(3-wire type), or limit switch can be used. Two-wire type muting sensor cannot be used.
