Optical Sensors - Photoelectric, Industrial

Optical sensors, particularly photoelectric and industrial sensors, have been developed and used since the 1930s for various monitoring and detection tasks. A unique example of this technology is the 70156-3234, an advanced optical sensor known as a light curtain. This device is used in industrial applications as a safety measure to protect personnel against hazardous machinery. This article will provide a brief overview of the 70156-3234 application field and working principle.The 70156-3234 is an optoelectronic detector composed of several light sensing elements which work together to shield personnel from dangerous machinery. Optimally, the components of the device can detect both visible and invisible rays from a maximum distance of 7.6 meters (approximately 25 feet). Furthermore, the installation of the 70156-3234 is not limited to horizontal positioning and can be tailored according to the specific orientation of the workplace.This type of device is particularly well suited for use in areas where hazardous machinery is operated, such as factories, printing presses, and CNC machines. It is also used in other areas, such as laboratories, where experiments involving dangerous chemicals or particles are conducted. In all scenarios, the primary goal of the device is to provide personnel with secure protection by preventing entry into a hazardous area.The 70156-3234 relies on a light sensing principle to detect any movement within its designated safety zone. In operation, a "light curtain" is created by the device, which constantly monitors the area and blocks access if any unauthorized presence is detected. The “light curtain” is composed of a set of optical beams that stretch across the distance it can detect, and each set of sensors is composed of a receiver and an emitter. During the normal functioning of the device, an uninterrupted flow of light is established between the receiver and emitter. In the event that an unauthorized presence is detected, the light beams are interrupted and the device\'s automatic cut-off system is activated, preventing entry into the hazardous area.In summary, the 70156-3234 is an advanced optical sensor designed for industrial use, particularly for providing personnel with secure protection against hazardous machinery. It can detect both visible and invisible rays from a maximum distance of 7.6 meters and has the capability to generate a “light curtain” which blocks access to a hazardous area if any unauthorized presence is detected. In addition to these advantages, the device is easy to install and can be adapted to various orientations in the workplace.
