Description
The 45CPD sensor is a Class 1 infrared laser sensor that provides
long distance sensing with both analog and discrete outputs. It is
set up using the Teach-In buttons on the top of the sensor and
can be programmed for several modes depending on the
application: object detection (single or dual output), object
position (analog output), object detection (background
suppression), or object detection (reflector mode).
This sensor utilizes the time of flight principle and has a relatively
small beam spot for applications typical for this sensing range (up
to 6 m). The sensor is completely self contained in an IP67
enclosure and does not require any external control devices
which add cost and require additional mounting space.
For convenience purposes, the 45CPD utilizes a visible red Class 2
laser for alignment purposes during the set up of the sensor in an
application. The Class 2 laser is automatically shut down when the
sensor is placed in normal operation and the Class 1 “eye safe”
laser is used.
The 45CPD can be easily set up by mounting the sensor such that
the target is within the operating range of the sensor, and
teaching in the appropriate set points required for the
application. The sensor can be set with any combination of 1 or 2
discrete PNP outputs and 4…20 mA analog output. The discrete
outputs can be set for Light Operate (L.O.) or Dark Operate (D.O.)
and the analog output is automatically scaled between the
taught set points with either a positive or negative slope.
The 45CPD is an excellent solution for long range detection and
measurement applications including: distance measurement,
verifying material position, stack level, thickness measurement,
roll diameter, web winding/unwinding, positioning fixtures, error
proofing, inspection, long standoff distance (hot or limited space),
level monitoring, and box width measurement.
