PHOTOSWITCH® Photoelectric sensors. The 45LMS family of long distance laser sensors is available in a variety of measuring ranges. The 8 m diffuse and 50 m retro-reflective 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 five-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 principle and has a relatively small beam spot even at 50 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 or dark operate 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 photo sensors. Eye safe class-1 or class-2 laser (by model). Sensing ranges of 8, 15 or 50 m, dependent on model. One discrete output (1 x NPN or PNP) and one analog output (1 x 4 to 20 mA). Easy setup of switch points or analog scaling using programming buttons IP65 enclosure. Self-contained sensor.
