Class 1 Invisible Laser Measuring Sensor For Process Automation

Short Description:

The customized laser ranging sensor S91-C1 uses a class of invisible laser, less than 0.4mW, safe for human eyes. One category refers to the output light power of the visible light laser is less than 0.4mW, which is generally considered safe for human eyes, and normal exposure to the beam of this laser will not cause permanent damage to the retina of the eye.

Internationally, there is a unified classification and unified safety warning signs for lasers. Lasers are divided into four categories (Class 1~Class 4). Class I lasers are safe for humans, Class II lasers cause minor harm to humans, and Class III and above lasers are safe for humans. Lasers can cause serious harm to people, so special attention should be paid when using them to avoid direct exposure to human eyes.

S91-C1 laser distance sensor has good performance in many special applications, such as medical treatment, monitoring system and so on.

Product Introduction

S91-C1 laser ranging sensor, the measuring range is 0.03~5m, the measuring accuracy is +/-1mm, the measuring time is 0.4-4s, the power supply voltage of the laser ranging module is 3.3V, and the protective shell is installed, which can The increased voltage is 5~32V, the working temperature is 0-40℃, and a class of invisible laser is used, 620~690nm, <0.4mW, which is safe for human eyes. It is anti-interference, and still has high measurement accuracy and reliability in outdoor environments. In addition, the application is simple, the power consumption is stable, and the power consumption is very small.

Seakeda laser distance sensor can transmit data through RS232, RS485, USB, TTL and other interfaces, and can also be connected to MCU, Raspberry Pi, Arduino, industrial computer, PLC and other equipment. Please contact us for connection diagrams.

Working Principle

The laser range tof sensor can quickly and accurately measure the distance to the target. It adopts the principle of phase measurement, which uses the frequency of the radio band to modulate the amplitude of the laser beam and measure the phase delay generated by the modulated light going back and forth to the measuring line once. Then, according to the wavelength of the modulated light, the distance represented by the phase delay is converted. That is, the indirect method is used to measure the time required for the light to go through the round trip.
