Industrial Laser Ranging Sensor RS232 Output

Short Description:

M92 series laser distance sensor was developed for fast and precise distance measuring, even in difficult measurement conditions, like Dust and fog, with poor reflect laser signal level. The laser sensor extremely small and lightweight make it suitable for size and weight limited applications, such as portable devices, industrial robot, medical system, etc.

Measuring Range: 0.03~40m

Accuracy: +/-1mm

Frequency: 3Hz

Communication Interface: RS232
