PHOTOSWITCH Distance Measurement Sensor
Catalog Numbers 45DMS-B8LAT1-D4, 45DMS-B8LGT1-D5
Description
The PHOTOSWITCH® distance measurement photoelectric sensor is
a compact, time-of-flight sensor that is ideal for measurement
applications in material handling and packaging environments.
Background-suppression sensing modes are ideal for applications where
highly reflective backgrounds must be ignored while helping to provide
excellent reliability detection of targets within the specified range.
The distance measurement sensor also offers a background reflection
(also known as foreground suppression) sensing mode that enables
operators to use the surface of a background (for example, a conveyor) as
a reflector. The detection of a target occurs once an object blocks the
visual path between the sensor and the background (for example, a
conveyor).
Features
• 5 m (16.4 ft) sensing range to 90% white and 3 m (9.8 ft)
sensing range for 6% black target
• 1 mm (0.04 in.) resolution via IO-Link™ and 5 mm (0.2 in.)
resolution with 4…20 mA or 0…10V analog output
• ± 30 mm (1.18 in.) maximum linearity for distance
measurement applications
• Eye Safe Class 1 Laser for ease of alignment and installation
• Distance measurement, background suppression, and
background reflection sensing modes selectable using
IO-Link™
• Discrete only, 4…20 mA and 0…10 V on analog with adjustable
range using the push buttons
• Enhanced sensor diagnostics when using IO-Link 1.1 point-to-
point protocol helps customers minimize machine downtime
and increase productivity
• Additional virtual output when using IO-Link
• IP69K rated enclosure

provides indicator status in the RUN mode during sensor
operation. The sensor is always in run mode except when the teach
sequence is in process.
