1. Introduction 1.1 Operation principles The UTM-30LX-EW uses a laser source (λ=905nm) to scan a 270º semicircular field (Figure 1). It measures the distance for each angular step to objects in its range. The measurement data along with its angular step are transmitted via a communication channel. The laser safety is class 1. 2.

6. Interface 6.1 Robot Cable 4 Pin Color Brown Blue Green White Function +12 V 0V Synchronous Output COM Output (0V) Note: 0 V of the power supply (Blue) and COM Output (0V) (White) are not internally connected. Connect them, when it is necessary. 6.2 Ethernet Cable RJ-45 plug is attached to the cable. (Length: 300mm ) This sensor is compatible with SCIP2.2 communication protocol standard. 6.
7. Control Signal Synchronous Output (UTM-30LX) 1 pulse is approximately 1 ms. Output signal Synchronization timing chart is shown below (Figure 3).
8. Malfunction Output: 1. Laser malfunction: When the laser does not emit or exceeds safety class 1. 2. Motor malfunction: When the rotation speed differs from the default value (> 25 ms). Synchronous/Warning signal will be turned OFF when these malfunctions are detected. The motor and laser will also stop. The details of error can be obtained via communication. [ Error code] The cause of an error can be acquired from a "STAT" line of the "II" command response of the SCIP communications protocol.
10. Cautions The heat is generated as the internal circuit of the sensor runs at a very high speed. The generated heat is concentrated at the bottom of the sensor. Please mount a heat sink or any appropriate component to release the heat. An aluminum plate (200mm x 200mm x 2mm) is recommended as the heat sink. Mutual Interference could occur when two or more identical sensors are mounted at the same detection plane. This is because the sensor could not identify the origin of the received laser pulses.
