Bulletin 45CPD Analog Laser Sensor

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.

The 45CPD sensor is a Class 2 laser product. It utilizes a Class 2 visible red laser for alignment purposes during the set up. After the sensor has been set up and is placed in the normal operation mode, the Class 2 laser is shut down and a Class 1 Infrared laser operates the device.

There is a natural eye aversion when looking into the laser beam of a Class 2 laser. Do not look directly into the laser beam or suppress the reflex to close your eyes.

The 45CPD should be mounted such that it is not directed at people (head height) and the beam path is terminated at the end of its functional path.

The laser safety label on the 45CPD sensor should be visible after installation.

Wiring

The 45CPD photoelectric sensor is available with a micro quickdisconnect for ease of installation and maintenance. Rockwell Automation recommends the use of the 889 Series of cordsets and patchcords for quick disconnect model sensors. All external wiring should conform to the National Electric Code and all applicable local codes.

Mounting

Securely mount the sensor on a firm, stable surface or support for reliable operation. A mounting which is subjected to excessive vibration or shifting may cause intermittent operation. The 45CPD-BKT1 mounting bracket is available for installation convenience. Once securely mounted, the sensor can be wired per the attached wiring diagram.
