1. General

1-1．Operation principle

The UST-05LN is a scanning laser range finder. The sensor emits pulsed laser beams within a

270° field of view. When the emitted laser beams are reflected back from an object, its distance is

measured by applying the Time-of-Flight (TOF) principle. The sensor has 541 measurement steps

with a 0.5° pitch.

The user can preset up to 31 area patterns in the sensor. Each area has 3 outputs; Output 1, Output 2 and Output

3 (see Figure 1). When the sensor detects an object in the area, corresponding outputs are switched to an OFF

state.

1-2. Area configuration

The user can configure areas in the sensor using application software provided by the manufacturer. Install the

software in a supported operating system and connect the sensor using a USB cable. See section 6 for details on

types of area configuration.

1-3．Area switching

The sensor has 5 external inputs for switching the area. Provide the correct signal states on these inputs (see Table

1) to switch the area.

1-4．Malfunction output

The sensor has a self-diagnostic function. It switches the malfunction output to an OFF state when errors are

detected in the internal components.

1-5．Synchronous operation

The sensor has a scanner synchronization function to avoid mutual interference between multiple sensors. To use

this function connect the Synchronous Output of one sensor (master) to the Synchronous Input of the other (slave).

The slave sensor adjusts its scanner position with a preset time lag from the master. The time lag can be specified

using the application software.
