Optical Sensors - Photoelectric, Industrial

Optical sensors are a type of sensor used to detect measurements that use light energy to measure various parameters including position, displacement, color, temperature, distance, and speed. The 70156-2139 is an industrial optical sensor designed for high-precision applications in industrial and laboratory conditions.

Design and Features

The 70156-2139 optical sensor is made of a plastic enclosure with a rubber gasket seal to reduce the risk of moisture or dust infiltration. The device has a small circular lens located at the front of the device and a xenon checker tube located at the back. The lens is used to collect the light emitted by the LED checker tube. The detector can detect object distances of up to 10m and features an output signal that is proportional to the measured distance.

Application Field and Working Principle

The 70156-2139 is designed to be used in industrial applications where high precision measurements and accuracy are paramount. The device is designed for use in robotics, motion control systems, and automated assembly lines. The device works by transmitting a light signal from the LED checker tube and detecting the reflected signal with the lens. The device uses the time of flight (TOF) technique to calculate the travel time of the light and, in turn, the distance of the object.

Technical Specifications

The 70156-2139 features a highly accurate measurement system with a resolution of 0.5mm and an accuracy of ±2mm. The device operates in a wide temperature range of -20°C to +50°C and has an operating voltage range of 6.5V to 23V. The device includes two output modes, PWM (pulse width modulation) and analog, and the device has a maximum detection rate of 250Hz. Additionally the device includes an integrated LED and can operate in either normal or inverse output mode.

Conclusion

The 70156-2139 industrial optical sensor is a highly accurate and reliable device designed for industrial applications. The device features a wide range of technical specifications and features and is designed to provide accurate and reliable measurements in a variety of conditions. The device is ideal for robotics, motion control systems, and automated assembly lines.
