45LMS Laser Measurement Sensor

Description

The 45LMS family of long distance laser sensors is available in a variety of measuring ranges. The 8 m diffuse and 50 m retroreflective models use a Class 1 visible red laser and the 15 m diffuse models use a Class 2 visible red laser. The discrete and analog outputs can be easily set using the 5-step rotary switch and the push button. Potential applications include object position (analog output) and object detection (background suppression with discrete output).

This sensor utilizes the Time of Flight (ToF) principle and has a relatively small beam spot even at 15 m away. The sensor is completely self-contained and does not require any external control devices which add cost and require additional mounting space.

The 45LMS is 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. All sensors in this family have one discrete output with one analog output. The discrete output can be wired for either Light Operate (L.O.) or Dark Operate (D.O.) and the analog output is automatically scaled between the selected set-points with either a positive or negative slope.

The 45LMS is an excellent solution for long range detection and measurement applications including: distance measurement, verifying material position, stack level, thickness measurement, roll diameter, positioning fixtures, error proofing inspection, long standoff distance, level monitoring, crane crash protection and other difficult applications that exceed the capabilities of standard diffuse or background suppression photosensors.

Features

• Eye Safe Class 1 or Class 2 laser (by model)

• 8 m (26 ft.), 15 m (49 ft.) or 50 m (164 ft.) sensing range, dependent on model

• One discrete output (1 x NPN/PNP) and one analog output (1 x 4…20 mA)

• Easy setup of switch points or analog scaling using programming buttons

• IP65 enclosure

• Self-contained sensor

This installation instruction should be read and understood before operating the sensor.

The 45LMS sensor should only be installed by qualified personnel.

The 45LMS is not a safety component as described by the EU machinery directives.

The 8 m & 50 m models of the 45LMS are Class 1 laser products. A Class 1 laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE) is impossible to exceed.

The 15 m models of the 45LMS are Class 2 laser products. A Class 2 laser is not safe to stare at continuously; however, the blink reflex of the human eye will prevent eye damage, unless the person deliberately stares into the beam for an extended period of time.

Wiring

NPN or PNP (Push-Pull)

The 45LMS 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.

The 45LMS features a Push-Pull discrete output. This means the outputs always drive either 24V or 0V and can therefore be wired like either an NPN or a PNP sensor.

Mounting

Securely mount the sensor on a firm, stable surface or support for reliable operation. A mounting subject to excessive vibration or shifting may cause intermittent operation. The 45LMS-BKT1 mounting bracket is available for installation convenience. Once securely mounted, the sensor can be wired per the wiring instructions in the next section.

Controls and indicators

Setting the sensor

The 45LMS is set up using the Rotary Switch and the SET button, and it displays feedback via the Yellow and Green LED indicators on the top of the sensor.

Upon completion of any set-point Teach, both LEDs flash simultaneously, followed by alternating flashing of the LEDs.

• A successful Teach is indicated by a slower alternating flashing (2.5 Hz).

• An unsuccessful Teach is indicated by a faster alternating flashing (8 Hz). After an unsuccessful Teach, the sensor continues to operate with the previous valid setting.
