The GDK-3 series photoelectric switches are industrial-grade detection devices that utilize advanced optical sensing technology. They use infrared light waves as the detection medium to achieve non-contact detection of the presence, position, or movement status of objects. This series of photoelectric switches includes various models, such as GDK-3-R6N2 and GDK-3-DS80M1, with a detection distance of generally 80cm, a working voltage of DC10-30V, and an NPN normally open output form. The switches are housed in robust ABS engineering plastic enclosures, which offer excellent impact resistance and corrosion resistance. They can operate stably within a temperature range of -25℃ to +55℃. Moreover, the GDK-3 series photoelectric switches have several advantages, including compact size, comprehensive functions, wire lead-out design, built-in power supply, relay high-power output capability, wide voltage range, and good anti-vibration performance. In terms of price, the cost varies depending on the model and configuration, and it is recommended to consult the relevant manufacturers for specific prices. The manufacturers of the GDK-3 series photoelectric switches include Shanghai Shuangxu Electronics Co., Ltd and Shanghai Wujiu Automation Equipment Co., Ltd. These manufacturers not only possess professional technical capabilities but also provide good after-sales service and high-quality solutions.
