Product Overview

– Sensor Heartbeat™ feature helps ensure excellent reliability operation
by indicating to the PLC if a sensor has lost connectivity due to sensor
failure or faulty wiring.
– Margin Low Alarm minimizes downtime by indicating when the
sensor is about to fail due to insufficient light being reflected.
– Signal Strength provides the raw measurement value of the amount of
light reflected from the target.
– Margin Levels displays the excess gain above the sensor threshold to
help reliably detect the target.
– Contrast Levels display the difference between the light signal levels
that the sensor read the last time that the output was ON versus the last
time the output was OFF. The IO-Link parameter contrast levels help
identify enough difference between the target and the background.
– Margin Low and High Indication Multipliers allow for specific
minimum margin levels when the local indication LED indicates
marginal conditions and stable conditions.
– Location Indication helps locate the sensors in large machines where
there are several units close to each other.
– Alignment Mode facilitates the alignment of the sensors in applications
where a transmitted beam receiver or a polarized retroreflective sensor
must be optimally aligned.
– Timers and Counters add additional sensor functionality by allowing
the operator to count the number of times a target has been detected.
– Timers and Counters add additional sensor functionality by allowing
the operator to count the number of times a target has been detected.
– Pin 2 Enable parameter allows continuous monitoring of the sensor
while providing access to a discrete output. Pin 2 Enable is ideal for
applications where high-speed sensor detection is critical to the
application.
– Process Data Maps allow for selection of the type of information that is
continuously sent to the PLC as a process data parameter.
– Temperature allows operators to visualize the internal temperature
value and to increase or decrease depending on the influence of the
ambient temperature on the internal sensor temperature.
