3 Sensor Configuration
• Expert™ 4-pin background suppression, retroreflective, and opposed mode receiver models are configurable using
either the sealed push button or the remote input wire.
• 3-pin fixed field and opposed mode emitter models require no user adjustments.
• The remote input wire (pin-2/white wire) is used to select light or dark operate or perform the desired TEACH
method. Pulse durations for the remote input wire correspond to the indicated press durations of the push button.
3.1 Remote Configuration – 4-Pin Models
The remote input wire (pin-2/white wire) is used to select light or dark operate, or perform the desired TEACH method.
Closing and opening times for the remote input wire correspond to the indicated press/hold durations of the push button.
3.2 Two-Point Static Background Suppression
Two-point TEACH sets a single switch point. The sensor sets the switch point between two taught target distances, relative
to the shifted origin location.
1. Present the target.

3.4 Dynamic Background Suppression
Dynamic TEACH sets a single switch point during machine run conditions. Dynamic TEACH is recommended for
applications where a machine or process may not be stopped for teaching. The sensor takes multiple samples and the
switch point is set just behind the farthest taught target distance, accounting for a static background.
1. Present the target.

Present the first target. The sensor-to-target
distance must be within the sensor's range.
